Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, yesterday said silicon wafers were damaged at one of its plants in Tainan following a magnitude 6.4 earthquake, but that no more than 1 percent of first-quarter shipments would be affected.
The company — whose customers include Apple Inc and Qualcomm Inc — operates one of its largest 12-inch wafer production facilities in the Southern Taiwan Science Park (南部科學園區).
TSMC acting spokeswoman Elizabeth Sun (孫又文) said the earthquake did not cause equipment to shift position, but wafers in the process of manufacture had been broken.
“Damage to wafers in progress remains under assessment, but TSMC’s initial estimate is that more than 95 percent of the tools can be fully restored to normal in two to three days,” the chipmaker said in a statement.
“The company ... does not expect the earthquake to affect first quarter wafer shipments by more than 1 percent. TSMC will soon notify affected customers and will recover any lost production as soon as possible,” the statement said.
Staff were safe and the firm’s Tainan facilities were structurally intact, Sun said.
“We will increase production activity,” she said.
United Microelectronics Corp (UMC, 聯電) chief financial officer Liu Chi-tung (劉啟東) said by telephone that there were no injuries or damage at its four chip factories in Tainan, although its machines would need recalibrating.
UMC — the nation’s No. 2 contract chipmaker — said the automatic safety measures at a plant in Tainan triggered equipment shutdown that affected work-in-progress wafers.
“However, normal operations are resuming and wafer shipments will not be affected,” UMC said in a statement.
The two chipmakers also said their production lines in Hsinchu and Taichung have not been affected by the temblor.
Advanced Semiconductor Engineering Inc (ASE, 日月光) — which tests chips before they reach device assemblers — said operations in Kaohsiung were unaffected, while smaller rival ChipMOS Technologies Inc (南茂) said it expects only a very minor impact at its manufacturing operations in the Tainan Science Park — primarily due to power interruption.
Catcher Technology Co (可成), which makes casings for Apple’s iPhones, iPads and MacBooks, said its Tainan manufacturing facilities were not damaged by the earthquake.
Innolux Corp (群創), the nation’s largest LCD panel maker, said all eight of its factories in Tainan were shut down automatically after the quake and that production is being resumed gradually, while Corning Inc, a supplier of glass substrate for panel makers with one factory in Tainan, said it did not suffer any damage to its facility and it is examining its operation lines.
INFRASTRUCTURE: Work on the second segment, from Kaohsiung to Pingtung, is expected to begin in 2028 and be completed by 2039, the railway bureau said Planned high-speed rail (HSR) extensions would blanket Taiwan proper in four 90-minute commute blocs to facilitate regional economic and livelihood integration, Railway Bureau Deputy Director-General Yang Cheng-chun (楊正君) said in an interview published yesterday. A project to extend the high-speed rail from Zuoying Station in Kaohsiung to Pingtung County’s Lioukuaicuo Township (六塊厝) is the first part of the bureau’s greater plan to expand rail coverage, he told the Liberty Times (sister paper of the Taipei Times). The bureau’s long-term plan is to build a loop to circle Taiwan proper that would consist of four sections running from Taipei to Hualien, Hualien to
The Civil Aviation Administration yesterday said that it is considering punishments for China Airlines (CAL) and Starlux Airlines for making hard landings and overworking their cabin crew when the nation was hit by Typhoon Kong-rey in October last year. The civil aviation authority launched an investigation after media reported that many airlines were forced to divert their flights to different airports or go around after failing to land when the typhoon affected the nation on Oct. 30 and 31 last year. The agency reviewed 503 flights dispatched by Taiwanese airlines during those two days, as well as weather data, flight hours
A relatively large earthquake may strike within the next two weeks, following a magnitude 5.2 temblor that shook Taitung County this morning, the Central Weather Administration (CWA) said. An earthquake struck at 8:18am today 10.2km west of Taitung County Hall in Taitung City at a relatively shallow depth of 6.5km, CWA data showed. The largest intensity of 4 was felt in Taitung and Pingtung counties, which received an alert notice, while areas north of Taichung did not feel any shaking, the CWA said. The earthquake was the result of the collision between the Philippine Plate and the Eurasian Plate, the agency said, adding
Three people have had their citizenship revoked after authorities confirmed that they hold Chinese ID cards, Mainland Affairs Council (MAC) Deputy Minister and spokesman Liang Wen-chieh (梁文傑) said yesterday. Two of the three people were featured in a recent video about Beijing’s “united front” tactics by YouTuber Pa Chiung (八炯) and Taiwanese rapper Chen Po-yuan (陳柏源), including Su Shi-en (蘇士恩), who displayed a Chinese ID card in the video, and taekwondo athlete Lee Tung-hsien (李東憲), who mentioned he had obtained a Chinese ID card in a telephone call with Chen, Liang told the council’s weekly news conference. Lee, who reportedly worked in
