Russia Sanctions: Taiwan's TSMC Joins Western Ban on Technology For Moscow

[Riaz Haq]

Taiwan Semiconductor Manufacturing Company (TSMC) will no longer fabricate computer chips for Russia, according to media reports. The ban will particularly affect Russia's Elbrus and Baikal processors, unless China agrees to step in to manufacture these chips, and risk additional US sanctions itself. Both Russian processors use mature 28 nm technology. The world's most advanced TSMC fabrication technology today is 5 nanometers. The best US-based Intel can do today is 7nm technology. China's SMIC (Semiconductor Manufacturing International Corporation) has the capability to produce chips using 14 nm technology.  Semiconductor chips form the core of all modern systems from automobiles to airplanes to smartphones, computers, home appliances, toys, telecommunications and advanced weapons systems.

China is the world's biggest producer of semiconductor chips, according to data from the United Nations. The electronics value chain, which includes consumer electronics and ICT, has been regionalized over the years, and China has become a major global production center for microelectronics, according to a report in Opportimes. Other major producers include South Korea, Singapore, Malaysia, the United States, Japan, Germany, the Philippines, the Netherlands, and Thailand. In particular, the statistics for China add up the production of Hong Kong and Macao.

While China is the  biggest volume producer of semiconductor components in the world,  the Chinese design centers and fabs rely on tools and equipment supplied by the West to deliver products. Western companies dominate all the key steps in this critical and highly complex industry, from chip design (led by U.S.-based Nvidia, Intel, Qualcomm and AMD and Britain’s ARM) to the fabrication of advanced chips (led by Intel, Taiwan’s TSMC and South Korea’s Samsung ) and the sophisticated machines that etch chip designs onto wafers (produced by Applied Materials and Lam Research in the U.S., the Netherlands’ ASML Holding and Japan’s Tokyo Electron ), according to the Wall Street Journal.

There is no question that the current western technology sanctions can seriously squeeze Russia. However, overusing such sanctions could backfire in the long run if the US rivals, particularly China and Russia, decide to invest billions of dollars to build their own capacity. This would seriously erode western technology domination and result in major market share losses for the US tech companies, particularly those in Silicon Valley.

TSMC says Nanjing wafer fab expansion plans on track as second quarter revenue surges 28 per cent

https://www.scmp.com/tech/tech-trends/article/3141240/tsmc-says-nan...

Volume production of 28-nm wafers in Nanjing will begin in the second half of 2022, reaching 40,000 wafers per month by mid-2023, said TSMC
Apart from Nanjing, the Taiwan foundry said its new plant in Arizona is proceeding and it is also in talks to build a new fab in Japan

Taiwan Semiconductor Manufacturing Co (TSMC), the world’s largest contract producer of advanced chips, said on Thursday it will press ahead with its 28-nanometre fab expansion in Nanjing, defying speculation that the project could be affected by US-China tech rivalry.
“We are further expanding our presence in Nanjing with 28-nm technology to support our customers’ urgent needs,” Mark Liu, chairman of TSMC, said during a conference call with analysts on Thursday. “The volume production will begin in the second half of 2022, reaching 40,000 wafers per month capacity by mid-2023.”
Liu said the 28-nm line will be “the sweet spot for our embedded memory applications” and he expects structural demand for 28-nm to be strong.

Economic Weapons of Mass Destruction

https://www.project-syndicate.org/commentary/economic-wmds-and-the-...

By RAGHURAM G. RAJAN


Because Russia's war against Ukraine could not go unpunished, the use of painful, sweeping economic sanctions is clearly justified. In the future, though, these powerful new tools will need to be subject to proper controls; otherwise, they could trigger a reversal of globalization – and of the prosperity that it has made possible.

CHICAGO – War is horrific, no matter how it is waged. Nevertheless, Russia’s unprovoked attack on Ukraine, with its scenes of Ukrainian civilians being murdered or driven from their homes, undoubtedly had to be opposed. In addition to supplying Ukraine with military weapons, governments around the world have deployed economic weapons against Russia. While Russia, an economic midget relative to its military power, may still lash out by expanding the range of military weapons it uses and the territories it targets, it is a risk the world had to take.

Compared to Russia’s indiscriminate bombing, economic weapons will not kill people as quickly, create as much visible destruction, or inspire as much fear. Nonetheless, the unprecedented economic weapons that have been deployed against Russia will be unquestionably painful.

The strictures on Russia’s central bank have already contributed to the ruble’s collapse, and new limitations on cross-border payments and financing have had an immediate impact, weakening confidence in Russian banks. Though trade sanctions (restricting exports of key inputs such as airplane parts to Russia, as well as purchases from Russia) and the exodus of multinational corporations from Russia will have a less immediate effect, they will reduce economic growth and increase unemployment significantly over time. If these measures are not reversed, they will eventually translate into lower living standards, poorer health, and more deaths in Russia.

That we have come to this point reflects a widespread political breakdown. Too many powerful countries are now being led by authoritarian rulers whose reliance on nationalism makes them less willing to compromise internationally and who face few domestic constraints on their behavior. If Russian President Vladimir Putin’s aggression were to go unpunished, more international provocations like his war in Ukraine would become inevitable.

Equally problematic is the breakdown of the international order. The United Nations Security Council cannot legitimately act against any of its permanent veto-wielding members (China, France, Russia, the United Kingdom, and the United States). The organization’s impotence translates into impunity for strongmen who flout international norms. Moreover, even if the UN could approve a military response, the will to confront a determined nuclear power militarily would probably be lacking.

Economic weapons, made possible by global integration, offer a way to bypass a paralyzed global governance system. They allow other powers an effective (that is, painful) but civilized way to respond to aggression and barbarity.



But the risks that these weapons can create must not be underplayed. When fully unleashed, sanctions, too, are weapons of mass destruction. They may not topple buildings or collapse bridges, but they destroy firms, financial institutions, livelihoods, and even lives. Like military WMDs, they inflict pain indiscriminately, striking both the culpable and the innocent. And if they are used too widely, they could reverse the process of globalization that has allowed the modern world to prosper.

By VIR SANGHVI


Even while the war in Ukraine rages, however, we should be asking ourselves deeper questions. A few days ago, at the ABP Ideas of India Summit in Mumbai, I interviewed Fareed Zakaria. Fareed’s view was that over the last decade or so, India has become so inward-looking and obsessed with its own issues and divisions that it has not spent enough time thinking about its place in the world, going forward.

While we have been obsessed with headscarves and caste arithmetic, the world has rearranged itself. No matter what happens in Ukraine, Russia will come out of the war damaged. If it makes peace, then some of the sanctions imposed on it by the West may be moderated but it seems unlikely that Putin’s Russia will become a full-fledged member of the global economy for a long time.

In that case, it will have no choice but to move into the Chinese sphere of influence. One scenario sees Russia as a classic vassal state of the Chinese, supplying energy and raw materials to feed the Chinese military machine and its industrial complex. Pakistan and China are longstanding allies, so we will probably see the emergence of a Russia-China-Pakistan alliance.

India will then have two choices. Either we agree to accept China’s suzerainty over the East. Or we look for other options.

Should we choose the second path (and I imagine we will have to), then there really is nowhere to go but the West. At present, the West understands how India is constrained by its dependence on Russian weaponry. But in the long run, it will expect a greater measure of alignment. Is that something we have considered? Or are we too blinded by the rhetoric about anti-Hindu America and hypocritical Washington?

Sooner, rather than later, we will have to rescue reality from the rhetoric.

Chinese Views of the US and Russia After the Russian Invasion of Ukraine
A new survey taken after the Russian invasion of Ukraine finds that the Chinese are very negative about the U.S., very positive about Russia – and very confident about China.



By Richard Q. Turcsanyi
May 14, 2022
https://thediplomat.com/2022/05/chinese-views-of-the-us-and-russia-...



Among the 25 countries respondents were asked about (Figure 1), Russia was the most positively perceived country with 80 percent of respondents saying they viewed Russia in a positive light while only 12 percent held negative views. The United States, on the other hand, was the most negatively viewed country in China with slightly more than 60 percent of respondents perceiving it negatively and 31 percent holding positive attitudes.

The other very positively perceived countries among Chinese respondents were Pakistan (73 percent), Singapore (66 percent), North Korea (62 percent), and Germany (61 percent). In turn, other very negatively perceived countries included India (56 percent), Japan (54 percent), Vietnam (48 percent), South Korea (47 percent), and Ukraine (46 percent).

-------------------

To get a more nuanced picture of the perceptions of the United States and Russia, we asked two open-ended questions in which the respondents provided their first associations with the respective country, and also a reason for why their image of the U.S. or Russia got better or worse.

In terms of the U.S. (see Figure 2), the most common association was “hegemon,” while other frequent expressions were “advanced,” “developed,” and “powerful,” but also “bossy,” “war,” “bandit,” and “sowing discord.”

----------------------

In the Russian case, the most common association was “warrior nation,” followed by words such as “Putin,” “vodka,” “vast,” “bears,” “powerful,” “war with Ukraine,” and “Sino-Russian friendship.”

------------

The picture we are getting is that both the United States and Russia are seen as powerful, but American power is seen mostly in negative terms, while Russia’s is almost exclusively positive. It may be noteworthy, however, that perceptions of Russia among the Chinese seem to be somewhat stereotypical and linked to the current leader, and might be lacking deeper social roots. Hence, these perceptions may be easily open to change.

When asked about how positively or negatively the respondents assess the foreign policy of major powers (Figure 4), only Russia (besides China) was seen positively, while the U.S. topped the negative ranking, ahead of India, Japan, and the European Union.



------------

Another major finding of the survey is Chinese people’s confidence in China. When asked about how militarily and economically powerful they perceive relevant major powers, China was seen as the most powerful one, while China’s culture was also perceived as the most attractive and Chinese universities were the most recommended ones.

We also asked how willing the respondents would be to get a COVID-19 vaccine produced by various countries. Again, Chinese vaccines were far more trusted than any other. This seems to be a result of two-plus years of propaganda painting the Western response to the pandemic in negative colors, presenting Western vaccines as ineffective, and even suggesting theories about the virus originating as a U.S. bioweapon. This may be a problem now, however, as Chinese vaccines don’t seem to be working as efficiently against the newer variants of COVID-19 as some Western ones.

India exercises strategic autonomy, worried at Russia’s ‘no limit’ China tilt
India News
Published on Aug 19, 2022 08:14 AM IST
National Security Advisor Ajit Doval made it clear to his Russian counterpart that India only takes decisions based on its national interests and questioned Russia’s “no limits” partnership with China as this directly impacted New Delhi’s security concerns.

https://www.hindustantimes.com/india-news/india-exercises-strategic...

National Security Advisor Ajit Doval had a heart-to-heart conversation with his Russian counterpart Nikolai Patrushev in Moscow this week with both sides discussing developments in Indo-Pacific, Ukraine and addressing each other’s concerns in the unfolding security scenario in Asia. Doval also met the newly appointed Russian Deputy Prime Minister in-charge of weapon industries Denis Manturov.

During his Moscow visit, NSA Doval dispelled any Russian notion that India had distanced itself from its strategic partner of the past and moved closer to the western camp. He made it clear to his interlocutors that India only takes decisions based on its self-interests and national security concerns and is not bound to any camp.

However, NSA Doval also conveyed that India was concerned about Russia leaning toward China, which had a long-standing boundary dispute with India and had recently flared up by PLA’s unilateral actions in the East Ladakh sector in May 2020. He said to date the boundary issue has been hanging fire with China still to restore April 2020 status quo ante in the East Ladakh sector.

The two sides discussed the Chinese power projection post House Speaker Nancy Pelosi's August 2 Taiwan visit with Russia expressing concern over the rapid militarization of the Indo-Pacific. With Russian energy exports from Vladivostok being impacted by the growing China-US tussle in the Indo-Pacific, Moscow is concerned about the military response by Japan, Taiwan and US over the Chinese missile firing around Taiwan post Pelosi’s visit.

While the two NSAs exchanged notes over the developments in the Ukraine war, it is quite evident that the western sanctions have hit the Russian military industrial complex as key spare parts from Europe can no longer be sourced due to American sanctions. In this context, Russia will increasingly become dependent on China for outsourcing hardware manufacturing and in turn weapon supplies to India will be hit. The Ukraine war is now into its sixth month with neither the Russian nor the Ukrainian forces being able to make a decisive move towards its objectives and the conflict bleeding both the economies.

At the NSA level dialogue, the two sides discussed cooperation in atomic energy, space, trade, and investment with both countries worried about the developments in Afghanistan. Despite the Taliban being in power for an year, Afghanistan continues to be restive with no space for minorities, women and children. The Central Asian Republics are seeing increasing economic penetration by Beijing much to the chagrin of Russia with countries bordering restive Xinjiang already in the Chinese debt trap through the enticing Belt Road Initiative (BRI).

Russia’s long-time chips failure coming home to roost
Russia will never be a first-rate power without a capable, innovative and commercially-oriented semiconductor industry

https://asiatimes.com/2022/08/russias-chips-failure-coming-home-to-...

In 1962, two Americans who spied for Russia and defected, Alfred Sarant and Joel Barr, proposed to turn the new Russian city of Zelenograd (“green city”) into a microelectronics and computer development and manufacturing center.

Zelenograd thus became the heart and soul of Russia’s effort to build modern electronics for its military. But it soon failed in its mission and the legacy of failure continues to this day.

Sarant and Barr, engineers who worked on classified US defense projects, mainly involving radar, had been part of the Rosenberg spy ring in the United States. Someone tipped them off that the arrests of Julius and Ethel Rosenberg were imminent.

Around the same time, British scientist and spy Klaus Fuchs was arrested in the United Kingdom. During World War II, he played a major scientific role at the US nuclear bomb-making site in Los Alamos.

Nikita Khrushchev took up Sarant and Barr’s proposal and turned Zelenograd into the heart of Soviet efforts to catch up with the US in electronics, including small computers and integrated circuits. Barr, who was a brilliant engineer, designed the first digital computers for Russia’s nuclear submarines and spearheaded the drive to build integrated circuits.

During the 1980s, the US launched a program of export controls and law enforcement efforts against Russian-backed “techno-bandits” who were supplying Russia with sophisticated equipment for their new electronics industry. Russian spying also went into high gear, going after US semiconductor designs needed to make Russian weapons more capable and “smart.”

There is a huge contrast in how the US dealt with Russia and its other emerging strategic rival, China. Russian development was stymied by strong controls while the US openly aided China in developing its now huge electronics industry.

One of the reasons Russian equipment destroyed in the Ukraine war is chock full of microchips made in the US, Europe and Asia is the plain fact that Russia cannot make them on its own. The export controls of the 1980s set the stage for Russia’s great microelectronics failure, which continues to afflict Zelenograd even today.

Russia’s two important semiconductor companies, Mikron and Angstrem, are located in Zelenograd. Angstrem was last reported in bankruptcy and there are also legal claims against former directors of its Angstrem-T division concerning “missing” equipment.

Mikron, the last great semiconductor hope for Russia, is working to develop technology that is already more than 2o years old, perhaps as out of date as 30 years. But the company is promising, not delivering.

It badly needs investments for a new foundry and for etching and laser equipment. Whether it will get the needed funding, or even if it could develop the requisite skill base, are open questions.

Bottom line: Russia cannot be a first-rate power without a capable electronics sector.

A good example is the lack of modern equipment in its aircraft and ground equipment. Russian tanks are operating without active protection systems, making them vulnerable to relatively cheap anti-tank weapons in Ukraine. Russian aircraft are flying without GPS mapping systems and some of them even lack ground targeting systems.

To be sure, these shortcomings do not mean that Russia will lose its war in Ukraine. However, Russia’s indigenous deficiencies in advanced electronics certainly does mean that it is suffering huge losses in equipment and manpower.

Russia’s high-tech industry is mostly focused on military requirements. That is far different from the US, China, South Korea, Japan, Taiwan or European producers, all of which have strong commercial sectors.

In the 1980s, the Pentagon wanted very high-speed integrated circuits. The Department of Defense thus started the Very High-Speed Integrated Circuit program (VHSIC) and invested in excess of $2 billion in the effort (about $5.5 billion in 2022 dollars).

It never succeeded in making any VHSIC integrated circuits, mostly because commercial processors far outperformed what the Pentagon aimed at producing. However, it did manage to subsidize US semiconductor equipment manufacturing, stimulating an industry that shipped much of its product abroad, mainly to Asia.

The VHSIC program illustrated, if a demonstration was needed, that a competitive commercial sector is vital to progress in electronics, as it is in many other industries.

The Russian approach, on the other hand, was to do everything in secret. During the Cold War, Zelenograd was a closed city and its work was classified.

Zelenograd increasingly fell into bad habits, mainly stealing others’ designs rather than developing them indigenously. A prominent example was the “Texas chip,” an important medium-scale integrated circuit the US was using in its aircraft radars and other hardware in the 1980s.

When Zelenograd’s engineers pushed for the development of their own home design, they were told by their superiors to copy the Texas chip and drop any independent design work.


Early on, a second disease infected Zelenograd. Joel Barr was Jewish and he was able to attract a lot of Jewish scientific and engineering talent to Zelenograd, even though it was a classified area where Jews in the USSR had trouble finding employment.

That was fine with Khrushchev but he was pushed out in 1964, two years after Zelenograd got started. Barr and the Jews were purged by Khrushchev’s successor Leonid Brezhnev, who considered all Jews agents of the West and unreliable. Similar anti-Jewish purges took place in all Russian defense industries and in universities and research organizations.

This was the period where the Soviet Jewry movement gained momentum in Russia, and where Jews and dissidents were demanding, among other things, the right to emigrate. The loss of a large component of Zelenograd’s creative sector, and its leader Barr, represented a significant setback for Moscow’s microelectronics program.

In the 1980s, the US had initially estimated that Russia was within a few years of catching up with it. But as a result of Russian secrecy, purges and a lack of access to Western know-how, Russia slipped irretrievably backward and behind.

By the late 1980s, Russia was seven to 10 years behind the US. Russia’s electronics technology slide was not reversed by the end of the Cold War – in fact, things got considerably worse.

The implications for Russian military power have been huge. Without advanced semiconductors, Russia will lose out on the next generation of smart weapons that will rely on very high-speed intelligent systems powered by artificial intelligence (AI).

AI requires specialized processors built to exacting specifications. China, for example, has just announced it now has a new advanced chip (a MinerVA Bitcoin mining chip) that can potentially compete with even better ones made by the world’s top chip maker, Taiwan Semiconductor Manufacturing Company (TSMC).

AI requires specialized processors built to exacting specifications. China, for example, has just announced it now has a new advanced chip (a MinerVA Bitcoin mining chip) that can potentially compete with even better ones made by the world’s top chip maker, Taiwan Semiconductor Manufacturing Company (TSMC).

While the Chinese chip is designed for Bitcoin applications, China is working toward advanced AI chips that can process massive amounts of information. China still has a way to go and lacks crucial extreme ultraviolet laser etching equipment, which it is being blocked access to by the US.

Russia may already be turning to China at least for lower-grade chips, but there is no evidence China is yet sharing any manufacturing know-how with Zelenograd. China has little to gain in helping Russia since supporting it would potentially result in broader sanctions against China’s electronics industry.

Today, Russia still lacks a credible and relevant domestic commercial electronics industry and is unlikely under current conditions to grow one in the near future. That would require significant foreign investment and access to the global electronics industry. Russia has shut itself out and what it hasn’t done to self-inflict harm, Western sanctions have done the rest.

Back in 1985, Mikhail Gorbachev visited Paris and met with then-president Francois Mitterand. Seeking a relaxation of the Cold War and better relations with the West, Gorbachev told Mitterand that Russia was merely a third-world country with nuclear weapons. Nearly 40 years later, that blunt assessment still rings true.

China chipmaker SMIC to build $7.5bn plant in Tianjin
Key producer ramps up capacity as Beijing pushes for stronger semiconductor industry


https://asia.nikkei.com/Business/Tech/Semiconductors/China-chipmake...

CHENGDU, China -- Semiconductor Manufacturing International Corp. will invest $7.5 billion to construct a new factory in the city of Tianjin, the Chinese chipmaker announced Friday, as China and the U.S. race to bolster their domestic chip supplies.

SMIC, China's largest contract chipmaker, has reached an agreement to set up a new subsidiary based in an economic development zone in Tianjin. It will have the capacity to produce 100,000 12-inch wafers a month, though SMIC did not say when operations are expected to begin.

The facility will specialize in production processes of 28 nanometers or larger. U.S. authorities appear to be restricting companies there from supplying SMIC with chipmaking equipment capable of handling 10 nm or more advanced process tech, which are required for cutting-edge semiconductors.

Amid tensions with the U.S., Chinese President Xi Jinping has been working to strengthen domestic industries in order to minimize the impact of American sanctions. The semiconductor industry has been at the heart of this push. SMIC, which counts a Chinese state-owned fund among its investors, plans to double its output from 2021 levels by 2025.

In Washington, U.S. President Joe Biden signed Thursday an executive order to create an interagency council to coordinate the implementation of the recently signed CHIPS and Science Act. He aims to swiftly distribute $52.7 billion in subsidies to the industry and to rebuild domestic supply chains.

SMIC has faced headwinds recently as cooling demand for smartphones and appliances squeeze the chip market. Combined with lockdowns and other strict restrictions under China's zero-COVID policy, the company logged its first year-on-year decline in net profit in three years last quarter.

SMIC has received financing from government funds and investment companies to build plants in Shanghai and elsewhere. It could receive similar assistance this time around.

#US Orders #Nvidia to Halt Sales of Top #AI Chips to #China. Nvidea says ban on its A100 & H100 chips designed to speed up machine learning could interfere with completion of developing the H100, its flagship chip it announced this year. #geopolitics

https://www.usnews.com/news/technology/articles/2022-08-31/nvidia-s...


By Stephen Nellis and Jane Lanhee Lee

(Reuters) -Chip designer Nvidia Corp said on Wednesday that U.S. officials told it to stop exporting two top computing chips for artificial intelligence work to China, a move that could cripple Chinese firms' ability to carry out advanced work like image recognition and hamper Nvidia's business in the country.

The announcement signals a major escalation of the U.S. crackdown on China's technological capabilities as tensions bubble over the fate of Taiwan, where chips for Nvidia and almost every other major chip firm are manufactured.

Nvidia shares fell 6.6% after hours. The company said the ban, which affects its A100 and H100 chips designed to speed up machine learning tasks, could interfere with completion of developing the H100, the flagship chip it announced this year.

Shares of rival Advanced Micro Devices Inc fell 3.7% after hours. An AMD spokesman told Reuters it had received new license requirements that will stop its MI250 artificial intelligence chips from being exported to China but it believes its MI100 chips will not be affected. AMD said it does not believe the new rules will have a material impact on its business.

Nvidia said U.S. officials told it the new rule "will address the risk that products may be used in, or diverted to, a 'military end use' or 'military end user' in China."

The U.S. Department of Commerce would not say what new criteria it has laid out for AI chips that can no longer be shipped to China but said it is reviewing its China-related policies and practices to "keep advanced technologies out of the wrong hands.

"While we are not in a position to outline specific policy changes at this time, we are taking a comprehensive approach to implement additional actions necessary related to technologies, end-uses, and end-users to protect U.S. national security and foreign policy interests," a spokesperson told Reuters.

The Chinese foreign ministry responded on Thursday by accusing the United States of attempting to impose a "tech blockade" on China, while its commerce ministry said such actions would undermine the stability of global supply chains.

"The U.S. continues to abuse export control measures to restrict exports of semiconductor-related items to China, which China firmly opposes," commerce ministry spokesperson Shu Jieting said at a news conference.

This is not the first time the U.S. has moved to choke off Chinese firms' supply of chips. In 2020, former president Donald Trump's administration banned suppliers from selling chips made using U.S. technology to tech giant Huawei without a special license.

Without American chips from companies like Nvidia and AMD, Chinese organizations will be unable to cost-effectively carry out the kind of advanced computing used for image and speech recognition, among many other tasks.

Image recognition and natural language processing are common in consumer applications like smartphones that can answer queries and tag photos. They also have military uses such as scouring satellite imagery for weapons or bases and filtering digital communications for intelligence-gathering purposes.

Nvidia said it had booked $400 million in sales of the affected chips this quarter to China that could be lost if firms decide not to buy alternative Nvidia products. It said it plans to apply for exemptions to the rule.

Stacy Rasgon, a financial analyst with Bernstein, said the disclosure signaled that about 10% of Nvidia's data center sales were coming from China and that the hit to sales was likely "manageable" for Nvidia.
