Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday said it did not expect any direct effect on its production caused by China’s latest export controls on two rare metals essential for making semiconductors.
The Chinese Ministry of Commerce and General Administration of Customs announced on Monday that exports of gallium and germanium are to require a license starting from Aug. 1 over security concerns, as Beijing and Washington tussle over the global market for chips.
TSMC, whose clients include Apple Inc and Intel Corp, controls more than half the world’s output of the silicon wafers that are used to power everything from drip coffee machines to vehicles and missiles.

“After evaluation, we do not expect the export restrictions on raw materials gallium and germanium will have any direct impact on TSMC’s production,” the company said in a statement.
TSMC did not elaborate on the long-term indirect impacts, but said it would monitor the situation closely.
Minister of Economic Affairs Wang Mei-hua (王美花) downplayed the impact of the export controls, saying Chinese-mined germanium and gallium are mainly raw materials that are refined in countries such as the US and Japan.
“Taiwan imports the refined materials so the short-term impact is limited,” she told reporters on Tuesday.
“We will closely monitor the impact of long-term [export] restrictions on the international market in terms of pricing and supply,” Wang said.
Gallium, found in integrated circuits, LEDs and photovoltaic panels, among other things, is considered a critical raw material by the EU.
China accounted for 80 percent of global gallium production, a 2020 report by the European Commission said.
Germanium is essential for making optical fibers and infrared camera lenses, with 80 percent of it also coming from China, the same report said.
The export curbs follow Washington’s blacklisting of Chinese companies in recent years in a move aimed at cutting them off from access to US technologies, including the most advanced chips.
China is sparring with the US over a range of issues including technology, trade and Taiwan.
BUSINESS UPDATE: The iPhone assembler said operations outlook is expected to show quarter-on-quarter and year-on-year growth for the second quarter Hon Hai Precision Industry Co (鴻海精密) yesterday reported strong growth in sales last month, potentially raising expectations for iPhone sales while artificial intelligence (AI)-related business booms. The company, which assembles the majority of Apple Inc’s smartphones, reported a 19.03 percent rise in monthly sales to NT$510.9 billion (US$15.78 billion), from NT$429.22 billion in the same period last year. On a monthly basis, sales rose 14.16 percent, it said. The company in a statement said that last month’s revenue was a record-breaking April performance. Hon Hai, known also as Foxconn Technology Group (富士康科技集團), assembles most iPhones, but the company is diversifying its business to
Apple Inc has been developing a homegrown chip to run artificial intelligence (AI) tools in data centers, although it is unclear if the semiconductor would ever be deployed, the Wall Street Journal reported on Monday. The effort would build on Apple’s previous efforts to make in-house chips, which run in its iPhones, Macs and other devices, according to the Journal, which cited unidentified people familiar with the matter. The server project is code-named ACDC (Apple Chips in Data Center) within the company, aiming to utilize Apple’s expertise in chip design for the company’s server infrastructure, the newspaper said. While this initiative has been
GlobalWafers Co (環球晶圓), the world’s No. 3 silicon wafer supplier, yesterday said that revenue would rise moderately in the second half of this year, driven primarily by robust demand for advanced wafers used in high-bandwidth memory (HBM) chips, a key component of artificial intelligence (AI) technology. “The first quarter is the lowest point of this cycle. The second half will be better than the first for the whole semiconductor industry and for GlobalWafers,” chairwoman Doris Hsu (徐秀蘭) said during an online investors’ conference. “HBM would definitely be the key growth driver in the second half,” Hsu said. “That is our big hope
The consumer price index (CPI) last month eased to 1.95 percent, below the central bank’s 2 percent target, as food and entertainment cost increases decelerated, helped by stable egg prices, the Directorate-General of Budget, Accounting and Statistics (DGBAS) said yesterday. The slowdown bucked predictions by policymakers and academics that inflationary pressures would build up following double-digit electricity rate hikes on April 1. “The latest CPI data came after the cost of eating out and rent grew moderately amid mixed international raw material prices,” DGBAS official Tsao Chih-hung (曹志弘) told a news conference in Taipei. The central bank in March raised interest rates by
