China’s Chip Industry Is Doomed

Monday, September 19th, 2022

This is a story that’s been bubbling on for a while, but it looks like the U.S. government is about to slam down export restrictions on chipmaking equipment.

The administration of US President Joe Biden next month is to broaden curbs on US exports to China of semiconductors used for artificial intelligence and chipmaking tools, several people familiar with the matter said.

The US Department of Commerce intends to publish new regulations based on restrictions communicated in letters earlier this year to three US companies — KLA Corp, Lam Research Corp and Applied Materials Inc, the people said, speaking on the condition of anonymity.

Every wafer fabrication plant in the world uses equipment from one of those three companies. Applied Materials and LAM Research (along with Tokyo Electron) have their fingers in almost all areas of chipmaking equipment (PVD, CVD, Etch, etc.), while KLA (formerly KLA-Tencor) dominates the wafer inspection equipment segment. Add ASML in the Netherlands, and those five absolutely dominate the semiconductor equipment market.

The letters, which the companies publicly acknowledged, forbade them from exporting chipmaking equipment to Chinese factories that produce advanced semiconductors with sub-14 nanometer processes unless the sellers obtain commerce department licenses.

This is where things get tricky. SMIC claims they can do 7nm, but everyone outside China doubts they can do it reliably, repeatably and profitably. SMIC announced they’re about to start manufacturing 14nm, and that they can probably do. Practically, they’re the only semiconductor manufacturer in China that can do sub-14nm, as just about everyone at the top of the next biggest semiconductor manufacturer, Tsinghua Unigroup, just got arrested in July.

There’s even talk that they’re actually zeroing in on FinFET technology specifically, though they may also ban sales of older chipmaking equipment as well.

Without a continued stream of machines, spare parts and technical know-how from those five semiconductor giants, China’s semiconductor industry is doomed. China’s domestic semiconductor equipment industry is essentially garbage, and they’re so far behind in so many areas that they can’t even steal their way to parity. The knowledge gulf is just too vast.

Min-Hua Chiang at the Heritage Foundation notes just how badly China’s domestic semiconductor industry is screwed.

According to World Trade Organization statistics, China’s trade deficit in integrated circuits and electronic components (including Hong Kong’s trade deficit) has almost doubled from the equivalent of $135 billion in 2010 to $240 billion in 2020.

The growing trade deficit in integrated circuits reveals one crucial fact: Achieving technological self-reliance is still a faraway Chinese dream. To keep its exports growing, China has no other way but to keep importing advanced chips to assemble into consumer goods with high-tech intensity (e.g., smartphones, tablets, and the like).

Although China (including Hong Kong) is also the largest exporter of semiconductor chips in the world, less than 7% of chips produced in China were made by Chinese semiconductor companies in 2021.

More than 90% of chips produced in China are made by foreign firms. In other words, China’s exports of semiconductor chips are overwhelmingly dominated by foreign companies.

Its inferior level of technology is the main reason for China’s chip reliance on foreign firms. While Chinese firms are stuck with advancing toward 7nm chips, the Taiwan Semiconductor Manufacturing Co. and Samsung are progressing towards mass production of 3nm chips this year. Intel plans to take over TSMC’s leading role in semiconductor technology by 2025.

The competition among a few tech giants in the U.S., Taiwan, and South Korea is clear, and the Chinese firms are not likely to jump into the global technology competition in the semiconductor industry anytime soon.

The U.S. restrictions on exporting chipmaking equipment to China’s largest semiconductor firm, Semiconductor Manufacturing International Corp., have not only deterred China’s technological advancement, but also exposed the fundamental mismanagement problems inside China’s semiconductor industry.

Xi might not have noticed his industry’s poor performance had China been able to continue to produce chips with foreign equipment.

Some parts about the Tsinghua scandal snipped.

Several Taiwanese executives leaving China’s semiconductor industry last year is another major setback in the development of China’s semiconductor industry.

China not only spent tremendously on building chip plants and purchasing expansive equipment, but also on recruiting talent from overseas. Over the past few years, China recruited more than 3,000 skilled workers from Taiwan to work in China’s semiconductor industry.

China amassed enormous capital, talent, and foreign equipment, but the problem is with governance. Xi’s absolute authority encouraged a rush into China’s semiconductor industry. Moreover, the extraordinary integration of the public and private sectors in China has twisted industrial development toward short-term profit-making, instead of long-term accumulation of manufacturing strength and technological improvement.

Xi’s “wolf warrior” diplomacy has further overshadowed the outlook of its semiconductor industry. China’s success relies on close partnerships with various suppliers and customers in different countries across the globe. Alienating them on the geopolitical front only undermines those relationships.

The U.S. ban on exporting chipmaking machines to China was the straw that broke the Chinese semiconductor industry’s back.

On top of that, the CHIPS and Science Act just signed into law bans semiconductor companies receiving U.S. government subsidies from investing in China for the next 10 years. There are major loopholes in that prohibition, but if Congress can manage to keep the administration’s feet to the fire—including by tightening the legal restrictions—it could have a major impact on China’s tech development.

In addition, the U.S. has extended the export restriction to 14 nm chipmaking machines to the Semiconductor Manufacturing International Corp. and other foreign chipmakers in China. A specific electronics design automation software for making advanced chips is also banned from exportation to China.

Without foreign investment and inputs, China is only likely to deepen its reliance on importing advanced chips from overseas.

Peter Zeihan notes (correctly) that China’s semiconductor industry has been singularly unable to fab advanced chips on their own.

Not to mention that fraud still abounds. Chinese CPU semiconductor startup Quillion Technology closed up shop three months after raising $89 million.

$89 million is probably enough to get you to tape-out for a fabless semiconductor house designing a smaller chip (or maybe even a low-power ARM-based CPUs for embedded markets), but it’s a woefully small sum for a real cutting-edge CPU company, and laughable if they intended to be an integrated design manufacturer fabbing their own chips, where building even a trailing edge fab starts in the billions.

Takeaways:

  • “Money seems to have a strong corruptive power over CCP officials that they can’t resist. Like China’s real estate industry, China’s semiconductor industry is also plagued with corruption, over-construction, and highly leveraged capital maneuvers.”
  • She goes over the history of the Chinese “Big Fund” for semiconductors I covered here, and later talks about the indictments.
  • “The state-run Semiconductor Investment Fund was used more as an instrument to speculate in stocks than an institution for conducting basic R&D. The government-backed fund, aka the “Big Fund,” has investments in 2,793 entities within three layers of ownership.” Very few of them have the word “semiconductor” in their names. (Like I said before, shell games all the way down.)

  • From 1984 to 1990, the Ministry of Electronics Industry delegated the management of the vast majority of state-owned electronics enterprises to local provincial and municipal governments. While these state-owned enterprises (SOEs) obtained more autonomy, something strange happened. These companies imported outdated integrated circuit production lines that had no commercial value. The wasteful projects cost money, but people used the opportunities to take foreign trips, receive kickbacks, and send their children abroad. And this happened on a large scale.

    Pretty much classic ChiCom behavior.

  • China’s high-tech industry, like its financial industry, is dominated by powerful CCP families, and the Jiang Zemin family is one of them. In 1999, Jiang Zemin gave his oldest son, Jiang Mianheng, the reins of China’s “autonomous chip development.” As vice president of the Chinese Academy of Sciences (CAS) and president of the Shanghai branch for many years, the junior Jiang has long held the turf of China’s science and technology sector. He is also personally involved in the semiconductor business. His Shanghai Lianhe investment has holdings of Shanghai Zhaoxin Semiconductor Company.

  • Classic story:

    Chen Jin, a former junior test engineer at Motorola, joined Shanghai Jiaotong University in 2001 after returning to China.
    He was given the responsibility to develop the “Hanxin” chip, an important part of the state-run high-tech development program known as the “863 Program.” In just three years, Chen obtained 100 million in R&D funding and applied for 12 national patents. On Feb. 26, 2003, Chen’s team officially released the “Hanxin 1” chip. The Shanghai Municipal Government, the Ministry of Information Industry, and the Chinese Academy of Sciences all backed his work. The expert panel declared the “Hanxin 1” and its related design and application development platform as being the first of its kind in China and achieving an important milestone in the history of China’s chip development. Subsequently, Hanxin 2, 3, 4 and 5 chips were launched, all of which were claimed to have reached an advanced level globally. The Hanxin series of chips even entered the General Equipment Procurement Department of the Chinese military. However, 3 years later, on Jan. 17, 2006, “Hanxin 1” was revealed to be completely fake. Chen downloaded a Motorola chip source code through a former Motorola colleague. Then he secretly bought a batch of Motorola dsp56800 series chips, paid a peasant to scrape the original Motorola logo with sandpaper, and asked a local Shanghai print shop to print the “Hanxin” logo on it.

    • China correctly identified semiconductors and semiconductor equipment as key technologies for truly becoming the world’s preeminent technological manufacturing giant. Unfortunately for them (and fortunately for us), the CCP’s endemic culture of corruption and their top-down command economy are antithetical to the onrush of capitalist technological innovation that powers Moore’s Law.

    A Good Explanation of the Semiconductor Shortage

    Tuesday, April 6th, 2021

    A semiconductor shortage has been plaguing the automobile industry for several months, and this piece explains why:

    To understand why the $450 billion semiconductor industry has lurched into crisis, a helpful place to start is a one-dollar part called a display driver.

    Correction: The semiconductor industry itself isn’t in crisis, it’s making money hand-over-fist right now. It’s certain industries relying on semiconductors that have the problem.

    Hundreds of different kinds of chips make up the global silicon industry, with the flashiest ones from Qualcomm Inc. and Intel Corp. going for $100 apiece to more than $1,000. Those run powerful computers or the shiny smartphone in your pocket. A display driver is mundane by contrast: Its sole purpose is to convey basic instructions for illuminating the screen on your phone, monitor or navigation system.

    The trouble for the chip industry — and increasingly companies beyond tech, like automakers — is that there aren’t enough display drivers to go around. Firms that make them can’t keep up with surging demand so prices are spiking. That’s contributing to short supplies and increasing costs for liquid crystal display panels, essential components for making televisions and laptops, as well as cars, airplanes and high-end refrigerators.

    “It’s not like you can just make do. If you have everything else, but you don’t have a display driver, then you can’t build your product,” says Stacy Rasgon, who covers the semiconductor industry for Sanford C. Bernstein.

    Now the crunch in a handful of such seemingly insignificant parts — power management chips are also in short supply, for example — is cascading through the global economy. Automakers like Ford Motor Co., Nissan Motor Co. and Volkswagen AG have already scaled back production, leading to estimates for more than $60 billion in lost revenue for the industry this year.

    A bit of background here: Back in the dim mists of time, some major car manufacturers used to have their own captive wafer fabrication plants for automotive components. They were more art-of-the-state than state-of-the-art, as well as heavily unionized. (Your etch machine broke? Better figure out whether you need the union plumber or the union electrician to fix it…) GM shut down their last semiconductor plan in Kokomo, Indiana (which I think was running a 500 nanomemter process, which was beyond old even then) in 2017.

    The situation is likely to get worse before it gets better. A rare winter storm in Texas knocked out swaths of U.S. production. A fire at a key Japan factory will shut the facility for a month. Samsung Electronics Co. warned of a “serious imbalance” in the industry, while Taiwan Semiconductor Manufacturing Co. said it can’t keep up with demand despite running factories at more than 100% of capacity.

    “I have never seen anything like this in the past 20 years since our company’s founding,” said Jordan Wu, co-founder and chief executive officer of Himax Technologies Co., a leading supplier of display drivers. “Every application is short of chips.”

    The chip crunch was born out of an understandable miscalculation as the coronavirus pandemic hit last year. When Covid-19 began spreading from China to the rest of the world, many companies anticipated people would cut back as times got tough.

    “I slashed all my projections. I was using the financial crisis as the model,” says Rasgon. “But demand was just really resilient.”

    People stuck at home started buying technology — and then kept buying. They purchased better computers and bigger displays so they could work remotely. They got their kids new laptops for distance learning. They scooped up 4K televisions, game consoles, milk frothers, air fryers and immersion blenders to make life under quarantine more palatable. The pandemic turned into an extended Black Friday onlinepalooza.

    Automakers were blindsided. They shut factories during the lockdown while demand crashed because no one could get to showrooms. They told suppliers to stop shipping components, including the chips that are increasingly essential for cars.

    Then late last year, demand began to pick up. People wanted to get out and they didn’t want to use public transportation. Automakers reopened factories and went hat in hand to chipmakers like TSMC and Samsung. Their response? Back of the line. They couldn’t make chips fast enough for their still-loyal customers.

    Here’s the crux of the problem:

    Wu explained that he can’t make more display drivers by pushing his workforce harder. Himax designs display drivers and then has them manufactured at a foundry like TSMC or United Microelectronics Corp. His chips are made on what’s artfully called “mature node” technology, equipment at least a couple generations behind the cutting-edge processes. These machines etch lines in silicon at a width of 16 nanometers or more, compared with 5 nanometers for high-end chips.​

    ​The bottleneck is that these mature chip-making lines are running flat out. Wu says the pandemic drove such strong demand that manufacturing partners can’t make enough display drivers for all the panels that go into computers, televisions and game consoles — plus all the new products that companies are putting screens into, like refrigerators, smart thermometers and car-entertainment systems.

    There’s been a particular squeeze in driver ICs for automotive systems because they’re usually made on 8-inch silicon wafers, rather than more advanced 12-inch wafers. Sumco Corp., one of the leading wafer manufacturers, reported production capacity for 8-inch equipment lines was about 5,000 wafers a month in 2020 — less than it was in 2017.

    Hell, there are people still running some four inch fab lines out there, though usually it’s for something funky like gallium arsenide, old analog signal processes, etc.

    The problem is, no one is building any new capacity in those old geometries because fabs are too expensive to build and need 2-3 years of lead time to get up and running. Moore’s second law states that the cost of a new, cutting edge semiconductor plant doubles every four years. You can’t just take an existing building and turn it into a fab, it has to be specially built from the ground up with exacting standards for cleanroom air filtering, concrete slab level uniformity, etc. And equipment manufacturers like Applied Materials and LAM Research aren’t going to sell you old technology machines to build older geometry chips because they’re not making them anymore. And if you have to pay full price for the equipment, you might as well fab higher-value chips in current geometries anyway.

    TSMC is already spending $100 billion for expanded manufacturing capacity over the next three years, and Intel another $20 billion. That spiraling fab cost is why so many former integrated device manufacturers went to a fabless model, designing chips but letting the manufacturing be handled by foundries like TSMC, UMC and Global Foundries. (And Intel is expanding their own foundry business at the same time they’re paying TSMC to fab some of their top-end chips. You can’t tell the players without a scorecard…)

    The other problem is the extremely cyclical nature of the semiconductor industry. In booms, fabs make money hand over fist. During busts, some segments (like RAM) barely break even. The foundry model has smoothed the spikes out somewhat, but as the current shortage shows, not entirely.

    Just-In-Time delivery was one of the great disruptive business innovations. Leaner, more tightly-coupled computerized inventory lead to decreases in unused parts and faster times to market. But when there’s a hiccup in the supply chain, it makes it more immediately disruptive. It’s hard to obtain additional semiconductor parts if everyone’s fab is already at full capacity, so expect shortages to extend into the year.
