Foundries pour on capacity to keep apace of wafer demand
By Mark Hachman and Mark LaPedus Electronic Buyers' News (10/22/99, 05:42:16 PM EDT)
With the financial perils associated with excess wafer capacity still fresh in their minds, wary chip-design houses are continuing to outsource their manufacturing. But a resurgent industry has quickly gobbled up available supply, and the world's foundries are again being pressed to meet demand.
In response, top-tier found- ries such as Chartered Semiconductor Pte. Ltd., IBM Corp., Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC), and United Microelectronics Corp. (UMC), are sharply ramping wafer capacity through significant capital investments.
The possibility of a widespread wafer shortage is prompting some customers to buy insurance in the form of guaranteed supply. Conexant Systems Inc. last week signed a $150 million deal to secure wafers from TSMC's Fab 6 in Tainan, Taiwan, in a move to outsource commodity CMOS products to its foundry partners.
?We're not going to build another fab ourselves,? said Dwight W. Decker, chairman and chief executive of Conexant, Newport Beach, Calif. ?Conexant will have access to a significant supply of wafers for a fraction of the cost of building a fab of our own.?
Chip makers, from Intersil and Lucent Technologies to Motorola and any number of vendors in Japan, are shedding the burden of fab start-up costs, although many still handcraft their treasured specialty lines. Indeed, in a move to protect their highest-margin ICs, a few integrated device manufacturers (IDMs) have reversed course and are staffing custom fabs that were on the block before the industry battled its way back from recession.
Even as it struck its deal last week with TSMC, Conexant said it would retain and expand its internal gallium-arsenide production. And in September, National Semiconductor Corp. said it was taking the for-sale sign down from its Greenock, Scotland, analog-IC manufacturing facility because of market demand.
However, by passing on new fab development, OEMs are becoming more dependent than ever on foundries to fulfill their everyday production needs. As a result, pure-play foundries will increase their share of capital expenditures from 15% in 1998 to about 20% of the estimated $35 billion that will be spent worldwide this year on semiconductor manufacturing, according to George Burns, president of Strategic Marketing Associates, Santa Cruz, Calif.
IDMs such as Motorola Inc. are expected to increase their manufacturing outsourcing to foundries from 15% of output today to as much as half of all production by 2002, according to Dataquest Inc., San Jose.
Burns said indicators like Microsoft Corp.'s recent earnings report, which unexpectedly characterized PC demand as ?awesome,? typify the demand cycle. But IDMs and foundries alike have maximized the capacity gains they can reap through process shrinks, and now must increase the manufacturing infrastructure itself.
Top-tier foundries such as TSMC and UMC are aggressively expanding capital- spending plans, while Chartered Semiconductor will float an initial public offering in the United States and in its homeland of Singapore to finance capacity expansion. IBM, also considered to be among the world's foundry leaders, is similarly expected to ramp capacity, although company executives declined to discuss their plans.
According to analysts, the supply/demand imbalance will weigh most heavily on top-tier foundries, the volume suppliers of leading-edge processes. In a report earlier this year, Phoenix-based Semico Research Corp. predicted demand for 8-in., 0.25-micron-processed wafers would reach 3.2 million units in 2000, but with an available supply of only 3 million wafers.
?What's happening is that everybody is continuing to go to the top three suppliers,? said Joanne Itow, a Semico analyst. ?They're easier to go to, experienced, and with good long-term relationships. There's other capacity available in second-tier companies, but it hasn't been tested.?
Even if chip designers determine they must shop for new production sources, it won't be easy to move from one foundry vendor to another. It takes months before a chip maker can get its products qualified at a new site, according to Dataquest analyst Jim Hines.
At an industry event hosted this week by the China External Trade Development Council (CETRA), foundry executives, not surprisingly, said they saw the upsurge coming as early as last year. Magnus Ryde, president of TSMC USA, San Jose, has more than doubled the company's December 1998 forecast and now says TSMC will make the equivalent of 1.9 million 8-in. wafers this year and 2.7 million in 2000.
To meet its aggressive forecast, TSMC will invest $1.6 billion this year in capital goods, an increase of $1 billion since June. Ryde said wafer demand is now about 80% higher than in 1998. The company's supply strategy is to exceed demand by 10%, although this will be difficult to accomplish in the near term, Ryde admitted.
?Next year, we anticipate greater demand than supply,? he said. ?There will be shortages next year, so the current demand picture looks very strong. There's a fair number of assumptions around that. First, the significant impact on memory prices has not been fully comprehended, as well as the impact on our customers. I would imagine there will be price increases in the industry, although maybe the constant price erosion on microprocessors will stop.?
More than half of TSMC's 1999 capacity will be at line widths of less than 0.35 micron, about the same percentage that will shift to 0.25 micron in 2000, Ryde said.
TSMC has increased capacity most heavily at its WaferTech joint venture in Camas, Wash., beefing up planned output this year by 107%, to 248,000 8-in. wafers. Decker said Conexant's cash infusion will be used to help bring up Fab 6 in Tainan, which is scheduled to produce finished wafers by February 2000.
UMC also plans sweeping capacity increases that are just slightly more modest than its rival's. UMC said it will ship the equivalent of 1.76 million 8-in. wafers this year, 2.4 million in 2000, and 2.9 million in 2001, including output from joint ventures. The corresponding investment levels have been pegged at $1.7 billion this year and $2.1 billion in 2000. In 2001, UMC's capital outlays are expected to jump to $2.9 billion, before leveling off to $3 billion in 2002.
?We have been telling people since June that we plan to ship over 1.2 million 0.25-micron-and-below 8-in. wafers next year, as a minimum,? said Jim Ballingall, vice president of worldwide marketing for UMC Group (USA) in San Jose. ?This is 50% of our total capacity next year.?
UMC will bring two fabs online in 2000: UMC5 in Hsinchu is projected to ship 100,000 8-in. wafers, and a second fab at United Semiconductor Corp. is expected to ship 85,000 wafers at process technologies approaching 0.1 micron.
Singapore's Chartered Semiconductor and Armonk, N.Y.-based IBM remained mum about their plans. Chartered is attempting to raise more than $400 million through an initial public offering to add manufacturing.
According to a prospectus filed with the Securities and Exchange Commission, the company is expected to spend about $620 million on new production this year and as much as $770 million in 2000. During the first half of 1999, Chartered shipped 327,300 8-in. wafers while using 94.8% of its available capacity.
A spokesman for IBM Microelectronics, Fishkill, N.Y., cited a long-standing company policy of not disclosing capacity or capital-spending levels.
As demand threatens to spill over the dam, other first- and second-tier foundries are hoping to avoid the knee-jerk reactions and quick-hit orders from suppliers scrambling for capacity. ?That's the last thing we need,? said Steve Morgan, director of North American sales for Tower Semiconductor USA Inc., the San Jose-based subsidiary of Israel's Tower Semiconductor Ltd. ?We're looking for longer-term relationships.?
And even had they welcomed the new business, most second-tier foundries are finding that demand has left them with little excess capacity. ?It's very tight right now,? said L.T. Guttadauro, sales director for Amkor Wafer Fabrication Services, Santa Clara, Calif.
Last month's earthquake in Taiwan, while apparently shrugged off by the island's larger foundries, has left some smaller manufacturers struggling to regain their balance. Hsinchu-based Worldwide Semiconductor Manufacturing Corp. (WSMC) was running at full capacity when the temblor struck, and two days later was devastated again when its emergency power generator overheated and caught fire.
Though the blaze was quickly contained, WSMC's fab is only past the 50% capacity mark now, and doesn't expect full production to resume until the end of November, according to president Richard Chang. The company lost 10,000 of the 100,000 wafers it expected to manufacture this year, although it will bring up two new 8-in.-wafer fabs next year, boosting overall capacity to 420,000 wafers.
To meet demand, WSMC has been forced to push one of its customers aside. The company had been building DRAM on a foundry basis for Fujitsu Ltd., but stopped manufacturing the devices to make room for non-DRAM products, Chang said.
Speaking at last week's CETRA event, Taiwan's foundry representatives gave what they said were final quake-damage estimates. Ryde said TSMC lost the equivalent of 80,000 8-in. wafers, about 28,000 of which were in the manufacturing process. Losses were concentrated at TSMC's Hsinchu fabs, which were closest to the quake's epicenter.
Arthur Kuo, a director at Hsinchu-based UMC, said his company lost 53,000 to 64,000 wafers, including about 16,000 that were in-process. |
