TSMC appointed Gina Proctor as treasurer of its TSMC Arizona Corporation subsidiary effective January 6, 2026, according to a regulatory disclosure filed in Taiwan.

Samsung Electronics is accelerating construction of its P5 semiconductor line in Pyeongtaek, South Korea, as it moves toward a 2028 production target. The project is a central component of the company's plan to expand memory production amid rising AI-driven demand. Samsung is currently mobilizing thousands of workers daily and has launched simultaneous bidding for utility infrastructure to compress the traditional build timeline.

Honda Motor said on January 5 that it would delay the reopening of three factories operated by its Chinese joint venture, GAC Honda, after a key automotive chip supplier, Nexperia, halted shipments. The restart, originally scheduled for January 5, has been pushed back two weeks to January 19.

Samsung Electronics will resume structural construction at its Pyeongtaek P5 semiconductor plant next month. The company halted the project last year during a downturn in the memory market, but is now expanding capacity as demand for high-bandwidth memory (HBM) used in AI recovers.

Taiwan's High Prosecutors' Office has filed a supplementary indictment against three additional suspects and the Japanese chip equipment maker Tokyo Electron (TEL) following new evidence in the investigation of a 2nm technology leak.

The economics of advanced semiconductor manufacturing in the US differ sharply from those in Taiwan, and TSMC's experience in Arizona is underscoring how difficult that gap is to bridge. Analysts say higher depreciation per wafer and elevated labor costs are placing sustained pressure on margins at the company's US fabs, even as production ramps up.

China's domestic foundry expansion gained momentum this week as Nexchip Semiconductor broke ground on its Phase IV project in Hefei, committing CNY35.5 billion (approx. US$5.07 billion) to expand 12-inch wafer capacity and deepen its position in mature-node manufacturing.
