台积电美国厂，获利锐减

Group 1 - TSMC's Q3 financial report indicates that its U.S. subsidiary earned only approximately NT$40 million in a single quarter, a significant drop from NT$4.232 billion in the previous quarter, highlighting the substantial costs associated with establishing operations in the U.S. [2] - The high operational expenses in the U.S. are attributed to the underdeveloped supply chain, technical talent training, and equipment maintenance compared to Taiwan and Japan, compounded by rising costs for expatriate engineering teams and facility setup [2] - TSMC's second wafer fab in Arizona is expected to complete equipment installation by Q2 2026, leading to increased depreciation burdens, making short-term financial improvements unlikely [2] Group 2 - The key to TSMC's U.S. operations lies not in immediate profit figures but in the successful implementation of advanced processes like 3nm and 2nm, which are crucial for increasing capacity utilization [2] - The demand for advanced packaging is rising, revealing a growing inadequacy in the local supply chain in the U.S., with several Taiwanese material and equipment manufacturers responding to TSMC's expansion by investing in U.S. projects [3] - The overall market is seeing sustained demand for advanced processes driven by AI, with 3nm and 2nm technologies remaining in long-term short supply, while mature processes face pricing pressures due to oversupply and competition from Chinese foundries [3]
