As China Races to Build Chips, Chipmakers Face ‘Serious Brain Drain
After graduating from one of China’s best universities
with a degree in microelectronics, Adam got a job as an engineer on one of
China’s most advanced chipmaking lines in Shanghai.
Every day, he woke up at 7 a.m. or 2 p.m., changed into a brightly colored
full-body suit, put his phone in a locker, and started a nearly 10-hour shift.
Adam was pretty much the ideal young person for China’s
economic planners: As China seeks to break free from its reliance on imported
chips, it’s counting on trained specialists like him to master the
sophisticated techniques needed to build up its homegrown semiconductor supply
chain.
But after years of hard work, he turned down an in-house
promotion and switched to a nearby chip design company last winter. His new
employer offered him a large raise, and he could say farewell to the assembly
line and the night shift and sit back in a swivel chair like a typical
white-collar worker. “Now I am a little junior in the office after changing my
career path, but I do not regret it,” said Adam, who can use his phone any time
he wants. He spoke to Sixth Tone anonymously because he is not authorized to
speak to the press.
In the past two years, it has become increasingly obvious
that chip manufacturing engineers are leaving fabs
and pouring into IC design houses.

He’s one of many. As China doubles down on its pursuit of
domestic chipmaking, the industry is losing
experienced specialists like Adam, according to industry experts and
executives.
Chips are hard
If you’re reading this story on an Apple or Huawei
product, the chip powering it was designed by the company itself. It’s a
challenging task mostly performed by specialized companies, or in-house by a
few of the world’s largest electronics makers.
But it pales in comparison to running an advanced
semiconductor fabrication plant, often called a “foundry” or “fab.” For years,
the components on chips have been getting smaller, allowing companies to print
more in a smaller space and creating computers that work faster.
The sizes of key components on advanced integrated
circuits (IC) have gone below 10 nanometers — only about 100 times the size of
an atom. Only a few companies in the world — the Taiwan Semiconductor
Manufacturing Company (TSMC), the U.S.’s Intel, and Korea’s Samsung — are able
to manufacture chips close to the cutting edge. Generations of chip technology
are named after their approximate sizes — 22 nanometer dates to 2012, 14
nanometer to 2014, and the current, 5 nanometer, was first made commercially by
TSMC in 2020.
While China has hundreds of competitive chip design
companies, including units at phone makers Huawei and Oppo
and internet giant Tencent, it has only a few major
semiconductor makers, most notably Shanghai’s Semiconductor Manufacturing
International Corporation (SMIC) and Huahong. They’re
several generations behind TSMC and Intel.

China’s leaders have worried about the country’s reliance
on imported semiconductors for years, but the issue spiked in priority in 2019,
when the United States banned sales to Huawei, one of China’s leading
technology companies. The company has struggled to find key components in the
wake of the ban, expecting its 2021 revenue to decrease by 28.9% compared with
a year ago, as U.S. sanctions continue to hit the company.
In response, China has accelerated efforts to develop
domestic capacity. Over the past 20 years, Beijing has subsidized China’s
chipmakers about $50 billion, according to the Semiconductor Industry
Association. In addition, from 2020, China will waive income taxes for chip
manufacturers with process technology under 28 nanometers for 10 years, and
allow chipmakers to import equipment and materials tax-free until 2030. China’s
national semiconductor investment fund, established in 2014, has raised an
overall $56 billion to date. The “Big Fund,” as it’s called, has invested $39
billion, of which nearly 70% has gone into the IC manufacturing sector,
according to research by the Semiconductor Industry Association.
‘Serious brain drain’
Chip manufacturing workers were listed in the top 100
occupations most in demand by the Ministry of Human Resources and Social
Security in 2021. But companies are having more trouble holding on to their
trained engineers.
“Though building domestic production lines has become
China’s priority, manufacturers, especially foundries, are facing a serious
brain drain now,” said a foundry executive, who spoke anonymously as he was not
authorized to speak to the media.
As the IC industry expands rapidly, semiconductor talent
is also in increasingly short supply. As corporations crave semiconductor
backgrounds and experienced talents, it’s easy to hop from manufacturing to a
better-paid, less arduous job in design.
Many colleagues of mine also cannot refuse such a
tempting salary increase. We put aside our passion and the mission to break
through the chokehold sanctions of the U.S. We are all just normal people.
- Adam, former foundry engineer
A survey by MooreElite,
an IC design service provider, found that for every 100 people employed by
chipmakers at the start of 2021, 14 quit their jobs in the first half of the
year. Furthermore, China will still face a talent shortage of over 200,000
semiconductor professionals in 2023, according to a white paper on “Talent in the Integrated Circuit Industry 2020-2021”
released by a group of industry associations.
Even China’s biggest chip manufacturer, SMIC, faces high
staff turnover. In 2020, SMIC lost 17% of its employees. Among those who quit
from SMIC, almost 70% were from the company’s Shanghai headquarters and Beijing
offices, according to its 2021 corporate social responsibility report. Most of SMIC’s fabs are
located in Shanghai and Beijing, including its three most advanced plants.
“In the past two years, it has become increasingly
obvious that chip manufacturing engineers are leaving fabs
and pouring into IC design houses,” said Wen Ge, a chip professional who is
active on the question-and-answer website Zhihu. He
told Sixth Tone that he has received hundreds of messages seeking career advice
on Zhihu from students and experienced chip
engineers. Most of them are interested in finding a better offer in IC design.
Where the money is
They’re often changing jobs to earn more money. Adam’s
career pivot from fab to IC design house, was worth almost an 80% salary rise.
As a newlywed keen to settle down in Shanghai, he found the offer irresistible.
Despite strong support from central and local
governments, China’s foundries are working with very constrained budgets.
They’re facilities that require enormous up-front investment, and take years to
recover costs. Some projects have failed. The most famous example is Hongxin Semiconductor Manufacturing in Wuhan, which
still owes contractors and investors billions of yuan.
A semiconductor fund manager told Sixth Tone that apart
from the government and state-owned enterprises, almost no one is capable and
willing to invest in foundries. Largely dependent on state funding, fabs operate frugally. This means spending on equipment and
materials to run and expand production lines, while scrimping on human
resources.
The pay gap between engineers at fabs
and other chip companies keeps widening. A survey of
leading semiconductor companies by recruitment platform 51job.com in 2021 shows
that earnings growth for manufacturing employees is almost half that of
different semiconductor sectors, at 10% to 15% every year.
“Many colleagues of mine also cannot refuse such a
tempting salary increase,” said Adam, “we put aside our passion and the mission
to break through the chokehold sanctions of the U.S. We are all just normal
people.”
The different working environments of fabs
and design companies also simplified talents’ decision-making. Fabs usually operate around the clock on three shifts,
surrounded by noisy machines and stifling air, but Adam’s new job has him
working a regular 10 a.m. to 6 p.m. shift in a bright and comfortable office.
Block on the road
The talent shortage is a big obstacle on China’s road to
a self-reliant chip supply chain.
In a meeting in Shanghai last November, Richard Chang Rugin, founder and former chief executive of SMIC, said
that “capital and policy support is not the problem” anymore, but the
industry’s lack of talent. Staffing is the most significant, and trickiest,
issue for China to increase semiconductor self-sufficiency, he said.
Talent “was simply not a topic … until China turned more
vocal to drive chip industry self-sufficiency from mid-2010s,” said Szeho Ng, head of Semiconductor Research at financial firm
China Renaissance, who added that China already fell short of achieving its
goal of 40% chip self-sufficiency in 2020. IC Insights, a research firm, predicted that chips produced in China will only account for
19% of its semiconductor market in 2025, far from Beijing’s goal of 70%.
Sandy, an engineer who works on advanced Chinese chipmaking lines, said it could be shortsighted to spend
budgets mostly on machines. With imports of advanced machines limited, she
says, they’re working on techniques to use machines designed for 28-nanometer
processes to make more advanced chips. Devising techniques like this will take
committed and talented engineers, she said. She spoke anonymously since she was
not authorized to speak to the press.
Where is the next generation?
The shortage of manufacturing talent is not likely to
abate soon. Wen said that college students avoid working fabs
when seeking internships and post-graduation jobs. In addition, the high costs
of experimental sites and equipment prevent many universities from providing
teaching manufacturing lines. Wen, who often receives career inquiries from
students, said that engineering students either keep away from professionals
who specialize in manufacturing or prepare to switch into IC design or coding
for internet companies by self-study and taking training courses before
graduating.
Increasing benefits for individuals in the chipmaking industry could alleviate the problem, “such as
offering hukou and reducing or exempting
employees’ taxes,” according to the foundry executives mentioned above. Hukou is a household registration system that gives
access to regional social services and other benefits.
Neil Shah, a technology analyst at research firm
Counterpoint, suggested that countries with semiconductor manufacturing
ambitions must formulate a holistic strategy to upskill the existing talent
pool, including moves like investing in higher education PhD programs and
forming cooperation, partnership, and exchange programs with industry-leading
companies and global universities. “It is going to be a marathon and not a
sprint.”
Many engineers in the fabs are
pinning their hopes on leading companies to reinvent the field. Huawei is
currently working with IC manufacturer Huarong
to build at least one fab. Sandy hopes the major company’s backing will allow
it to offer competitive salaries.
“When I heard that Huawei would start working on chip
manufacturing, I was excited. Huawei's employees suffer, but they get a
considerable sum of money,” said Sandy. “If the company provides wages and
incentives like that, the smartest brains will quickly gather around.”
