The semiconductor chip is at the core of what we think us as technology.
Computers, cell phones, iPods, medical equipment, avionics, etc. have only been
possible because of the chip. The American chip industry has been damaged by the
recent economic slowdown like most industries, but more importantly, the chip
business in the United States has been in a slow fall for 30 years.
In January global chip sales dropped by almost a third from the previous
year, to $15.3 billion (Semiconductor Industry Association). Overinvestment in
chip factories has resulted in steep losses of over the last 2 years. The chip
business has been compared to farming. If too many farmers plant cotton, then
the price of cotton will drop (supply and demand).
The American chip industry, outside of Intel, is an endangered species.
AT&T, Hewlett-Packard, and others are already gone from the field. Others,
like Texas Instruments, have set a path for the eventual elimination of
manufacturing. These companies have gone "fabless", meaning they will continue
designing applications, but leave the process technology and manufacturing to
someone else (most often to companies in Asia).
The microprocessor market has been the exception, especially Intel. The
microprocessor market has been controlled by Intel. It has been a kind of
monopoly. But Intel, when operating outside the microprocessor arena (i.e. DRAM
or Flash memory), has followed the general model.
Intel has recently closed 3 factories (the industry calls them "Fabs", short
for fabrication): one in Colorado, one in Oregon, and one in California. But
Intel is building microprocessor fabs at the same time, currently building a
factory in Phoenix and one in Israel. Intel is doing OK. Intel had over $12
billion of cash on hand at the end of 2008.
In 1980, one of the pivotal events in the history of the chip industry, was
IBM's selection of Intel to build the microprocessors for the IBM personal
computers. IBM chose Intel over Motorola and Zilog (Zilog was founded by
ex-Intel engineer Frederico Faggin, who invented the MOS process while at
Fairchild).
IBM insisted that Intel facilitate second sources for the microprocessors by
allowing companies like AMD to alternatively manufacture the chips. Intel's
wealth has been almost fully acquired because of their control of the personal
computer. IBM ceded control of the personal computer away with this agreement,
or more accurately, their failure to execute this agreement.
The Rise of the American Chip Industry
The Chip Industry has its roots firmly in the United States. Scientists at
AT&T Bell Labs invented the transistor in 1947. The chip, or integrated
circuit, was invented by Jack Kilby of Texas Instruments and Robert Noyce of
Fairchild (later Intel) in 1958. There were many interim steps between these two
seminal events, most accomplished by the teams from Fairchild and RCA.
In 1975, the U.S. had more than 70% of the world's market share for chips.
The chip industry titans during the development years were IBM, AT&T, Texas
Instruments, Motorola, and Hewlett-Packard. These were established technology
companies that had success in the emerging field.
Silicon Valley, in California, was largely the result of startup companies
with ties to Fairchild, who was located in the area. Fairchild was a technology
pioneer, but most of the success came from Fairchild alumni, what became known
as the "Fairchildren". Alumni from Fairchild founded Intel, AMD, National
Semiconductor, LSI Logic, Altera, Xilinx and many others. One notable Fairchild
alumni was Eugene Kleiner, who would later found Kleiner Perkins, a venture
capital firm that would help Amazon, Google and Sun Microsystems become
billion-dollar companies.
The Fall of the American Chip Industry
Since the U.S. had such a commanding market share in the 1970's, it was
natural that this position would be difficult to maintain. The first challenger
was Japan, who was very successful at capturing the DRAM market, at the time the
most important chip market. By the mid 1980s, 80 percent of the DRAM market
belonged to Japan.
Many outside of Asia fail to give proper credit to the emergence of Japan in
the chip industry. The common perception is that the sole reason for Japan's
success was low labor costs. In fact, the primary reason for Japan's ability to
manufacture at lower cost was a superior technical strategy. American DRAM
manufacturers switched to a lithography technology called "steppers" a
generation before the Japanese. The Japanese continued to utilize the previous
generation lithography technology called "scanners". The American companies
falsely believed that scanner technology would be inadequate for the newest
memory devices. Scanners are significantly faster and less expensive to operate
than steppers. Because the lithography step is so important to the overall
process, the Japanese had a significant advantage, and used that advantage to
capture the DRAM market.
In 1987 the United States started a research consortium called Sematech to
combat the loss of market share. The plan called for the chip companies to share
research costs, with a government subsidy. Member companies contributed $124
million to Sematech's 1990 budget and $100 million was contributed by the
government through the Defense Advanced Research Projects Agency (DARPA).
Japan's market share did drop in the early 1990's, but this was probably more
as a result of problems in the Japanese economy than with developments in the
U.S. chip industry. The Japanese stock market "bubble" burst, much like the
dot-com market burst in the United States. Japan's market share of total chip
sales peaked in 1988 at about 49%. Today, Japan's world market share of the chip
business is about 25%.
Sematech had a positive impact on the U.S. chip companies' circuit
reliability. Statistical process control (SPC) techniques were led by Sematech
and resulted in dramatic improvements. Motorola, a Sematech member, was the
first winner of the Malcolm Baldrige Quality Award. The progress in reliability
enabled chip customers to forego incoming inspection of chips, a huge cost
savings.
Sematech was very active helping an immature U.S. equipment industry improve
their tools. Sematech effectively moved the technology center of semiconductor
industry from chip manufacturers to the chip equipment companies like Applied
Materials and KLA. Before Sematech, the customers were the process experts, but
now the process tool companies included process expertise with the equipment.
This was very good for the lucky equipment companies, but Sematech was very
selective. Many tool vendors were shut out by Sematech.
Those outside the chip community sometimes fail to understand the degree to
which the chip equipment industry is internationalized. A fab requires hundreds
of different process tools for the many different process steps (some chips
require more than 500 process steps). Many of the tools cost more $1 million.
Most fabs will attempt to standardize on a tool supplier for a particular
process step, but all fabs have equipment from many different companies.
A few years ago, a major "Wall Street Analyst" cut his forecast of Applied
Materials' business prospects based on the growth of the Taiwan semiconductor
industry. The flaw in this logic is that a Taiwanese factory uses U.S. equipment
at about the same rate as a United States based company. U.S. companies also
commonly use equipment manufactured from outside the U.S, especially from
Japan.
Since the chip equipment industry is so globalized, if Sematech makes an
advance, U.S. companies gain little, if any, advantage. Chip manufacturing has
become highly homogeneous, from company to company, and from country to country.
Because the equipment companies now controlled the process technology, it became
much easier for countries like South Korea, Taiwan, and China to enter the
market. If a company had the money, the technology was for sale.
The result of the work done by the industry, especially by Sematech and its
Japanese counterpart, Tohoku University, was that the process of manufacturing
chips became less of an art, and more of a science. Chip manufacturing became
"paint by the numbers". Once the industry reached this level of maturity, the
price of capital, and the price of labor, became the dominant factors in the
choice of manufacturing location.
A state of the art fab requires an investment of $3-4 billion. Chip
manufacture is now a commodity business involving huge production volumes and
low profit margins. A recent count of the last 40 chip factories built showed
that 35 were in Asia, 3 were in the United States, and 2 were in Europe.
The memory market, including the products DRAM and Flash Memory, is the most
competitive chip arena. South Korean companies currently dominate the memory
market. Samsung is the leader, with more than 30 per cent market share, and
Hynix is second, with more than 18 per cent market share. Elpida (Taiwan) with
15 percent, Micron (U.S.) with 11 percent, and Qimonda (formerly
Siemens/Infineon, Germany, currently in bankruptcy) with 8 percent, are the
other significant market share holders.
The Emergence of the Chip Foundry
Chip manufacturing technology continues to become more of a commodity.
Companies that once designed, manufactured, and marketed chips, now hire a third
party for the manufacture step. This is what is meant by a "fabless" company.
The company that performs the manufacturing step is the "foundry". The design is
accomplished via collaboration between the foundry and the fabless company.
A modern foundry provides software tools so that the fabless company can
accomplish their objective using standard process cells, technology that is
owned by the foundry. One of the world's first chip foundries was created in
Taiwan by Texas Instruments in 1989 to manufacture DRAM. The company was called
TI-Acer.
Taiwan Semiconductor (TSMC), with $30 billion market capitalization, is the
current leader in the foundry chip industry, and currently boasts more than 44
per cent of the world market share of chip foundry business. TSMC was founded in
1987 as a joint venture of Philips (Netherlands), the government of Taiwan, and
private investors. Morris Chang is the founder of TSMC, and continues to serve
as the Chairman. Mr. Chang's resume includes 25 years at Texas Instruments,
leaving as a group vice president in charge of the company's worldwide
semiconductor business. TI-Acer merged with TSMC in 1999.
The world's second largest foundry is also in Taiwan. UMC claims more than
14% of the foundry business worldwide. Taiwan, a country about the size of
Vancouver, Canada, has the highest concentration of semiconductor manufacturing
in the world.
It is interesting to note that two of the executives instrumental in recent
events in the semiconductor industry are on the TSMC board of directors: Carly
Fiorina and Thomas Engibous.
Carly Fiorina is now best known as John McCain's Economic Advisor during the
last election. She is the former CEO of Hewlett Packard where she oversaw HP's
exit from the chip manufacturing business. In addition, Ms. Fiorina spent nearly
20 years at AT&T and Lucent Technologies Inc. where she served as Executive
Vice President, Computer Operations for Lucent and oversaw the exit of AT&T
from chip manufacturing.
Thomas J. Engibous (former Texas Instruments Chairman, former president and
CEO 1996 -2004), was the department manager of TI's semiconductor group when TI
established TI-Acer. Texas Instruments has eliminated their R&D operation,
and plans to be fabless for most of their production. TI was one of TSMC's first
customers. Much of the foundry model has roots from within Texas
Instruments.
The Future of the American Chip Industry
Intel will continue to dominate the Personal Computer microprocessor business
for the foreseeable future. There are threats. AMD does everything well except
make money. A Taiwan company called "Via" may be the more significant long-term
threat. Via designs the chips and manufactures them at the local foundries.
Via's core designs originated with Cyrix Semiconductor, a company started by
ex-Texas Instrument engineers. Cyrix was sold to Via in 1999. Via's processors
are competing well against the Intel "Atom" microprocessor, in less expensive
laptop computers.
AMD recently completed an agreement with a company from ATIC (Advanced
Technology Investment Company) funded by the Government of Dubai, that should
enable them to continue to compete with Intel. AMD plans to build (with their
partner), a chip manufacturing facility in Saratoga County, New York. AMD
currently manufactures all of its microprocessors in Dresden, Germany.
AMD has a technology exchange agreement with IBM. IBM continues to do well.
IBM's strategy is to participate in higher margin products and avoid commodity
markets like DRAM. IBM remains a world leader of chip technology.
Foreign companies continue to invest in U.S. fabs, but at a reduced rate.
Samsung is doing well with its DRAM factories in Round Rock, Texas, a few miles
north of Austin. Samsung operates two fabs; the newest fab opened in 2007 and is
considered state-of-the-art.
There are also success stories at the lower end of the technology scale.
X-Fab, a German company, operates a fab in Lubbock that is a bright star on a
bleak landscape. X-Fab excels by thinking "out-of-the-box", something
exceedingly rare in the chip industry today, ironic considering its history. It
would be impossible for X-Fab to compete in a high volume, low margin business
like DRAM, but they do very well with custom analog chip production. The
facility was originally built by Texas Instruments.
More than half of the chip fabs in the United States in in operation at the
beginning of the decade are now closed. Outside of Intel, there has been little
to cheer about. There is little mystery about what the future holds. Our actions
today determine our consequences tomorrow.
