[News] TSMC-Linked VIS’ Fab 3 Fire Puts Further Pressure on Tight 8-Inch Capacity

Amid tightening mature-node foundry capacity, a fire broke out late Aug. 27 at Vanguard International Semiconductor’s (VIS) Fab 3 in Taoyuan, prompting the evacuation of more than 200 employees, according to TechNews. TSMC currently holds a 19% stake in VIS.

As of press time, the company had not disclosed the fire’s impact on manufacturing or overall operations. The market is closely watching whether the fire will disrupt production or shipments, as the incident comes as demand for power management chips used in AI servers continues to rise, the report adds.

Industry sources cited by TechNews further noted that semiconductor fabs rely heavily on a range of utility systems—including power, gases, HVAC, exhaust and ultrapure water—in addition to process equipment. Key areas to monitor now are whether these systems and production tools remain fully operational, and whether wafers already in production have been affected, as highlighted by the report.

According to TechNews, VIS’ 8-inch wafer capacity is currently running close to full utilization. The company previously forecast that third-quarter wafer shipments would rise 1% to 3% sequentially, while average selling prices (ASP) were expected to increase 2% to 4%. Capacity utilization was projected to reach 90% in the third quarter and climb further in the fourth, Central News Agency reports.

Tighter 8-Inch Supply Raises Disruption Risks

TechNews also highlights concerns over VIS’ shrinking 8-inch capacity as the company continues to optimize its product mix and manufacturing processes. With capacity gradually shifting from wider- to smaller-linewidth processes, VIS’ total 8-inch capacity is expected to fall about 4% year over year to 3.306 million wafers, the report suggests.

Against this backdrop, a prolonged shutdown could put production schedules and customer deliveries under pressure, further tightening the supply-demand balance for 8-inch mature-node capacity—a dynamic the market will be watching closely.

VIS Chairman Fang Lueh, as noted by Central News Agency, already flagged that further price increases are now unavoidable. The company has begun discussions with customers over pricing adjustments for 2027, and given rising costs and the investment required to build additional capacity, the increase next year is expected to be no smaller than that seen in 2026, the report adds.
