GlobalWafers Inc (環球晶圓), the world’s No. 3 silicon wafer supplier, yesterday reiterated its positive outlook on business until 2025, as customers continue to show a strong interest in securing wafer supply by signing long-term supply agreements (LTAs).
The Hsinchu-based company saw prepayments from LTAs swell to a record NT$33.11 billion (US$1.12 billion), up 15 percent from the end of last year, undeterred by growing uncertainty about macro environmental risks including impact from COVID-19 lockdowns, the Russia-Ukraine war, rising interest rates, and higher energy and freight costs.
“We continue to sign LTA contracts, especially for larger diameter wafers and advanced products, with 300-millimeter wafers being our customers’ primary target,” GlobalWafers chairperson Doris Hsu (徐秀蘭) told investors at a teleconference.

“We have yet to see a cooling-off in demand from our customers,” Hsu said.
“There is some unevenness in the end market, with demand from the smartphone and notebook markets, for example, slowing slightly, while demand from the automotive, industrial and server markets continue to be very hot,” she added.
“So far, there has been no order cancelation or pushout from our customers,” she added.
Demand is strongest for all types of 300-millimeter wafers, followed by wafers made of compound semiconductor materials, mainly silicon carbide and gallium nitride, GlobalWafers said.
To satisfy the robust demand, the company said it was maintaining its NT$100 billion capacity expansion plan, which includes brownfield and greenfield projects at six sites in Taiwan, the US, Italy, South Korea, Japan and Denmark.
Much longer lead times in equipment delivery could create a bottleneck, and that could lead to a delay of one to two quarters in the construction of new production lines, Hsu said.
All production lines are running at full capacity, she said.
In the first quarter, GlobalWafers’ net profit plunged 35 percent year-on-year to NT$1.75 billion, dragged by a loss of more than NT$6 billion from a drop in 13.67 percent-held Siltronic AG’s market value and foreign exchange rate fluctuations.
That translated into earnings per share of NT$4.01, down from NT$6.18 a year earlier.
Excluding the unrealized losses from Siltronic, GlobalWafers would have seen a record profit of NT$14.16 per share last quarter, the company said.
Operating profit surged 49 percent to NT$5.89 billion, and gross margin improved to a record 42.6 percent, from 35.1 percent a year ago.
GlobalWafers said it is hard to predict whether its gross margin would be able to rise to the levels — 46 or 48 percent — posted by foundry companies or integrated device manufacturers, given the uncertainty arising from the impending imposition of a carbon emissions tax and higher energy costs.
Wafer manufacturing is a power-intensive industry, the company said.
RUN IT BACK: A succesful first project working with hyperscalers to design chips encouraged MediaTek to start a second project, aiming to hit stride in 2028 MediaTek Inc (聯發科), the world’s biggest smartphone chip supplier, yesterday said it is engaging a second hyperscaler to help design artificial intelligence (AI) accelerators used in data centers following a similar project expected to generate revenue streams soon. The first AI accelerator project is to bring in US$1 billion revenue next year and several billion US dollars more in 2027, MediaTek chief executive officer Rick Tsai (蔡力行) told a virtual investor conference yesterday. The second AI accelerator project is expected to contribute to revenue beginning in 2028, Tsai said. MediaTek yesterday raised its revenue forecast for the global AI accelerator used
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has secured three construction permits for its plan to build a state-of-the-art A14 wafer fab in Taichung, and is likely to start construction soon, the Central Taiwan Science Park Bureau said yesterday. Speaking with CNA, Wang Chun-chieh (王俊傑), deputy director general of the science park bureau, said the world’s largest contract chipmaker has received three construction permits — one to build a fab to roll out sophisticated chips, another to build a central utility plant to provide water and electricity for the facility and the other to build three office buildings. With the three permits, TSMC
The DBS Foundation yesterday announced the launch of two flagship programs, “Silver Motion” and “Happier Caregiver, Healthier Seniors,” in partnership with CCILU Ltd, Hondao Senior Citizens’ Welfare Foundation and the Garden of Hope Foundation to help Taiwan face the challenges of a rapidly aging population. The foundation said it would invest S$4.91 million (US$3.8 million) over three years to foster inclusion and resilience in an aging society. “Aging may bring challenges, but it also brings opportunities. With many Asian markets rapidly becoming super-aged, the DBS Foundation is working with a regional ecosystem of like-minded partners across the private, public and people sectors
BREAKTHROUGH TECH: Powertech expects its fan-out PLP system to become mainstream, saying it can offer three-times greater production throughput Chip packaging service provider Powertech Technology Inc (力成科技) plans to more than double its capital expenditures next year to more than NT$40 billion (US$1.31 billion) as demand for its new panel-level packaging (PLP) technology, primarily used in chips for artificial intelligence (AI) applications, has greatly exceeded what it can supply. A significant portion of the budget, about US$1 billion, would be earmarked for fan-out PLP technology, Powertech told investors yesterday. Its heavy investment in fan-out PLP technology over the past 10 years is expected to bear fruit in 2027 after the technology enters volume production, it said, adding that the tech would
