Demand is rising as AI training and inference workloads increase the need for high-quality wafers used in GPU processors and HBM stacks. Chiplet-based designs are also expected to increase the use of silicon interposers and TSVs. Hyperscale cloud programs may further raise procurement of GPU server silicon and related accelerator inputs. Regional supply planning is becoming important as buyers seek qualified wafer sources close to foundry and OSAT programs.

Third-Party Evidence Supports Semiconductor Demand

The Fact.MR page cites several dated third-party developments. SEMI, April 29, 2026, reported that worldwide silicon wafer shipments increased 13% year over year in Q1 2026. The page also cites GlobalWafers Co., Ltd., December 17, 2024, regarding U.S. CHIPS Act direct funding; Soitec SA, December 4, 2024, regarding collaboration with GlobalFoundries on high-performance RF-SOI production; and Ferrotec Holdings Corporation, June 23, 2026, regarding GlobalFoundries qualification of SLATE advanced packaging technology on its 9SW platform. The source page does not provide additional numeric statistics for those three company developments, so no extra figures are added here.
