Taiwan preps for battle in MEMS technology
TAIPEI, Taiwan — Taiwan is looking to repeat its megasuccess with semiconduct
ors by tackling both the design and manufacture of microelectromechanical syst
ems. At least 20 companies focusing on MEMS devices have set up shop here, wit
h more to come. At the top of the food chain are Walsin Lihwa Corp., a foundry
, and Asia Pacific Microsystems Inc., an integrated device manufacturer. The a
ctivity stems in part from a government drive to seed the MEMS industry here b
y setting up academic centers for R&D and by incubating design houses. The thi
rd prong of the MEMS strategy devised by Taiwan's government research lab, the
Industrial Technology Research Institute (ITRI), is to encourage the establis
hment of foundries, and within the past year the private sector has built a ha
ndful of them.
No one is sure which business model will work best for Taiwan — pure-play fou
ndry or integrated device manufacturer — and "at this point, we are incubatin
g both," said C.K. Lee, a MEMS researcher and key booster of the industry here
. "Both sides have their pros and cons. History says foundry will win. But the
IDM perspective is very interesting." Personally, Lee said he would like to s
ee a system design industry emerge, anchored by fabless companies, since that'
s where he thinks the better money will be.
"If Taiwan wants to move away from always being the low-cost manufacturer, the
n we must do this," Lee said. "We are in the right time and the right place fo
r MEMS."
Indeed, with a widening of potential uses, from car tires and hearing aids to
optical switches and microdisplays, interest in MEMS has gained considerable s
team worldwide in the past year or two. Design shops and MEMS fabs have been p
opping up everywhere, triggering a capacity glut in an industry barely off its
training wheels.
The Asia-Pacific region is especially active, with startups in China, India, J
apan, South Korea, Singapore and Taiwan all pursuing MEMS. Meanwhile, 54 fabs
are already established, 17 of them in the United States, seven in Germany, si
x in Japan and five in Taiwan, according to InStat/MDR.
Everyone is chasing a market expected by some estimates to hit $9.6 billion by
2006, up from about $3.9 billion last year. That includes revenue earned by w
ell-established players like Motorola Inc. and Texas Instruments Inc. with the
ir own devices. With so many players, cutthroat competition is a given and a s
hakeout seems inevitable.
"By and large I would say close to 50 percent of the MEMS startups have their
own in-house prototyping capability and as a result also have the capability f
or low-volume production," said Marlene Bourne, who covers emerging semiconduc
tor applications for InStat and recently finished a market report on MEMS.
Analysts believe the glut will worsen next year. Eventually, for those that su
rvive it, there may be some low-hanging fruit. The average selling price for M
EMS devices will shoot up 25 percent during the next five years, Bourne said,
as more expensive, nonsensor devices hit the market. She calculates the greate
st opportunities to be in the communications and consumer sectors. Based on re
venue, compound annual growth through 2006 should hit 151.4 percent and 42.2 p
ercent in those two market segments respectively, she said.
What gives Taiwan an edge, say industry players, is its strong background in f
oundries and CMOS manufacturing, plus its ability to drive costs down. Also po
tentially helpful is the close integration of Taiwan's academic R&D with the a
ctivities of local companies that are already producing more mature MEMS produ
cts, such as inkjet heads.
Two chief players
The two chief players in Taiwan, Walsin and Asia Pacific Microsystems (APM), a
re taking different paths to MEMS. Walsin, a conglomerate looking for growth,
is going the foundry route, while APM has set up as an integrated device manuf
acturer.
Already successful in traditional areas like steel, copper wiring and optical
fiber for power and telecommunications applications, Walsin also has semicondu
ctor experience through its stake in Winbond Electronics Corp., a memory and l
ogic maker. After a few fact-finding trips to the United States, Walsin presid
ent Cheng I-lin persuaded his group chairman to take the plunge into MEMS. A y
ear later, after $50 million in equipment purchases, the company says it is re
ady to process 5,000 eight-inch wafers per month in a Walsin factory once used
for making magnetic wires. Cheng hopes to reach 15 percent capacity utilizati
on by the end of the year.
"That's a small portion but we are a startup and have to prove our capability,
" he said. "We are not just making existing products. We are making some very
new structures that are only on the drawing board, so the challenge is how to
do it efficiently so that it makes economic sense."
Walsin initially transferred its process technology from ITRI, the government-
sponsored lab that has studied MEMS for several years and helped seed the indu
stry here. The startup is augmenting its know-how through additional technolog
y transfer and collaboration with Memscap, an emerging player based in Crolles
, France, that has impressed analysts.
Walsin will use the European company's RF-MEMS component designs and process r
ecipes to increase fabrication yields for devices such as inductors, switches
and variable capacitors. Walsin believes that will help it gain a foothold in
end markets including 3G mobile phones, wireless local loops and LANs, and eme
rging applications such as tunable antennas.
"RF MEMS will be another wave to boost the widespread use of MEMS technology a
nd applications," Cheng said. Optical MEMS will come about three to five years
later, in his view. The challenge there, he said, is proving reliability duri
ng the life span of the device. "A dust particle may impair the whole structur
e or the humidity will make the structure stick. In an optical switch, if some
thing like that happens, then your wavelength may be transmitted to somebody e
lse instead of the intended destination," Cheng said.
Consequently, the drivers are likely to be devices that don't require such a h
igh level of reliability. For instance, the first product at Asia Pacific Micr
osystems is a pressure sensor, a mature product that still has potential for h
igh growth. In 2006, the U.S. National Highway Traffic Safety Administration m
ay require such sensors in car tires.
APM, which has a 6-inch wafer fab coming online in October, has used the press
ure sensor product to tune its manufacturing process. Eventually, the company
says it will spin off its design units and operate as a pure-play foundry. But
at this early stage, APM executives believe the IDM model is necessary to get
money flowing in and establish a track record. "If you can deliver the pressu
re sensor, then you can guarantee the foundry service to some extent," said CE
O Lin Min-shyong.
Lin expects next year will be crucial for his business. By then the company ca
n show real products, developed on homegrown design and manufacturing processe
s, and hope that system design houses will start to notice. In communications,
for instance, Lin will be shopping an integrated RF module to old friend K.Y.
Lee, the CEO of Benq, an Acer Inc. subsidiary that makes computer peripherals
and handsets.
At the moment, most Taiwanese MEMS players have their own boutique design and
manufacturing processes. Because there are no standard processes or cell libra
ries, the engineering effort is often more complex and time-consuming than nec
essary.
There is talk of taking the "art" out of the manufacturing process, said InSta
t's Bourne, so that more products may be made on a generic process similar, in
theory, to the plain-vanilla ones offered by semiconductor foundries that fit
a wide range of customers with only minor tweaks. "The name of the game is to
get costs down to drive more market opportunities," Bourne said.
As competition with U.S., European and Japanese MEMS producers increases, Taiw
anese players are counting on their strong ties to university talent and resea
rch to give them an edge. MEMS researcher Lee and his students at National Tai
wan University are offering consultation services to local companies, which Le
e reports are gladly accepted. "Any major project must have a direct impact to
the local industry. At the same time, we require advanced research," he said.
Lee, who is a former IBM Corp. researcher, said that his experience at the U.S
. company "gave me a very strong perspective that high-tech requires lots of r
esearch."
