"President
Joe Biden is so proud of Taiwan Semiconductor Manufacturing Co.’s new
facility that he went to Arizona to celebrate it. A $40 billion
figure tends to attract heads of state and corporate chieftains, with
the chip factories TSMC is building there being hailed as the largest
foreign direct investment in US history.“Apple had to buy all the
advanced chips from overseas,” Biden said at the plant outside
Phoenix on Tuesday. “Now, they’re going to bring more of their supply
chain here at home. It could be a game changer.”
Unfortunately, Mr President, it won’t be a game changer.
Everything
announced by TSMC this week was in line with long-term plans for the
site. The amount of land it acquired indicates six distinct chip fabs.
The first was announced in May 2020 and scheduled to begin operations in
2024. A $12 billion figure was put on that first installment, which was
a bit of a misnomer because it also included operational costs over
nine years, not just the big-ticket capex number usually cited.
This
week comes news of the second factory, which will start manufacturing
in 2026, with the total budget now climbing to $40 billion. Expect
announcements for third, fourth and maybe fifth plants in coming years.
Also
keep an eye out for upgrades to the technology that will be
deployed. Much was made of news that TSMC would manufacture at the 4
nanometer node (dubbed N4) in Arizona. At that time, 7nm was the most
advanced available. A smaller metric means better technology, but thanks
to Moore’s Law, industry advancements occur rapidly. The company’s
timeline meant N4 would be available in Taiwan this year, two years
before it would reach the US.
This
week TSMC is lauding the fact that 3nm will hit Arizona in 2026,
whereas that same technology is scheduled to be unveiled in Taiwan next
year. In other words, the US will still be behind by two to three years,
or one to two generations of chip technology.
No
less important is capacity. TSMC’s Arizona fabs will produce 600,000
wafers annually. That sounds impressive, but it’s really not. The
Taiwanese company topped 14.2 million last year and is on track to churn
out 15.4 million 12-inch wafers loaded with chips this year. If it
keeps the same average capacity growth of 8.1% it achieved over the past
five years, Arizona will account for just 2.85% of its 21 million
annual global output in 2026.
That’s a drop in the bucket, not a game changer.
US
companies accounted for 64% of TSMC’s revenue last year.
Apple Inc. alone contributed 26%. Taking into account higher prices for
newer technologies and the fact that Apple is the key buyer of advanced
nodes, Bloomberg Opinion estimates the iPhone maker bought as much as
20% of TSMC’s capacity. To supply just Apple, the Taiwanese firm would
need to expand its US footprint by a further seven times if the
Cupertino company was to fully source its chips from home soil. That’s
just not going to happen.
Then
there are all the other US companies — such as Nvidia Corp., Qualcomm
Inc. and Advanced Micro Devices Inc. — that want to show off
American-made chips. To entirely satisfy the US appetite for chips from
local facilities, TSMC would need to spend around $1 trillion.
TSMC’s
latest announcement offers something for everyone. Biden is selling it
as a vote of confidence in the nation’s high-tech workforce, ignoring
the fact that TSMC founder Morris Chang has poured cold water on the US
ability to compete.
“There’s
a lack of manufacturing talents to begin with,” Chang told The
Brookings Institution earlier this year. “We did it at the urging of the
US government, and we felt that we should do it.”
Apple
Chief Executive Officer Tim Cook was quite transparent in his
enthusiasm for TSMC’s new fabs. The company develops its own
semiconductor designs and sends them to factories in Hsinchu, Taichung
and Tainan in Taiwan for manufacturing. As previously predicted,
Arizona serves as a marketing win for the Californian company: “Now,
thanks to the hard work of so many people, these chips can be proudly
stamped ‘Made in America,’” he said.
Proponents
of this project, and of government incentives used to secure these
factories, will note that even a small amount of leading-edge chipmaking
on home soil is better than nothing. That’s somewhat true, but it also
leaves the US exposed to tensions between China and Taiwan.
Research,
development, planning and operations will all remain in Taiwan. Should
Beijing decide to attack, those functions will cease at least
temporarily, if not permanently. This would mean cutting TSMC Arizona
off from all the crucial know-how it needs to run the minuscule capacity
it has on US soil. With the chip industry moving at break-neck speed,
it wouldn’t be long before thousands of jobs and billions of dollars in
infrastructure in Arizona would be at the mercy of a war 7,000 miles
away.
It may indeed be
the case that TSMC’s $40 billion spending bill is the largest foreign
direct investment, but that’s still not enough to ensure the US builds
itself a self-sufficient semiconductor industry. It just buys bragging
rights."
