Vanguard International Semiconductor is evaluating a second wafer fabrication facility in Singapore after the initial capacity at its first plant was fully booked ahead of schedule. The TSMC affiliate operates the project through VisionPower Semiconductor Manufacturing Company (VSMC), a joint venture with NXP Semiconductors. Its first 300mm wafer fab in Tampines opened on September 28, 2026, after being built in under two years. The facility’s initial capacity of roughly 44,000 wafers per month is expected to reach full utilization in 2028, one year earlier than previously projected. The plant cost approximately $6.7 billion, below the original $7.8 billion estimate, after the project shifted toward silicon interposer production licensed from TSMC using 30-40nm technology. Silicon interposers are components that connect multiple chips within advanced packages, including those used in AI systems. The fab produces specialty chips ranging from 130nm to 40nm for applications including vehicle braking systems, industrial equipment and advanced-chip packaging. TSMC holds a 27% stake in Vanguard International Semiconductor, and the project has created approximately 1,600 jobs. Volume production is targeted for the first quarter of 2027. The speed of that ramp and whether it confirms the demand projections behind the investment are expected to shape the timing of any second-facility announcement.
