两个晶圆厂，传停工

Core Insights - The global semiconductor industry is facing significant challenges, with several major wafer fabs halting operations, delaying construction, or closing production lines, leading to a substantial impact on the entire sector [1] Group 1: GlobalFoundries and STMicroelectronics - The joint wafer fab project between GlobalFoundries and STMicroelectronics in Crolles, France, has been stalled after 18 months of slow progress, with a total investment of €7.5 billion expected from the European Chips Act [2] - The new 12-inch semiconductor wafer fab was initially planned to be fully operational by 2026, with an annual capacity of 620,000 wafers [2] Group 2: Sumitomo Electric - Sumitomo Electric has decided to cancel its new silicon carbide (SiC) wafer fab project due to weak demand in the electric vehicle market and uncertainty regarding the recovery timeline, which was announced in 2023 with an investment plan of ¥30 billion [3] - The project aimed to produce 180,000 SiC wafers annually by 2027, but this plan has been completely scrapped [3] - Industry insiders suggest that Sumitomo Electric may redirect resources to other growth areas, such as automotive wiring harnesses and optical components for data centers, to offset losses in the SiC wafer business [3] Group 3: Wolfspeed - Wolfspeed announced plans to close its 6-inch SiC wafer fab in Durham, North Carolina, due to higher manufacturing costs compared to its 8-inch fab in Mohawk Valley, with the CEO indicating an evaluation of the closure timeline [4] - The construction of a 200mm SiC wafer fab in Ernsdorf, Germany, has been postponed from summer 2024 to 2025 [4] Group 4: Intel - Intel has delayed the construction of its Fab 29.1 and Fab 29.2 facilities near Magdeburg, Germany, due to pending EU subsidy approvals and the need to clear and reuse topsoil, with the start date pushed from summer 2024 to May 2025 [5] - The advanced manufacturing facilities using Intel's 14A (1.4nm) and 10A (1nm) processes, originally expected to begin operations by the end of 2027, are now estimated to start production between 2029 and 2030 [5] - Intel's chip project in Ohio, announced in January 2022 with an initial investment of over $20 billion, has also faced delays, with construction now pushed to 2026-2027 and expected operations starting in 2027-2028 due to weak market demand and delayed government subsidies [6]
