TAIPEI — Capital investment in the semiconductor sector is pivoting aggressively toward advanced packaging infrastructure as traditional wafer fabrication improvements yield diminishing returns. Leading foundries are reallocating capital expenditures to resolve bottlenecks in high-bandwidth memory (HBM) and chiplet integration processes.
Substrate and Silicon Interposer Shortages
The primary limit on high-performance computing chip deliveries is no longer front-end lithography, but the availability of advanced silicon interposers and organic substrates. Leading fabricators are operating advanced packaging lines at maximum capacity, driving long-term supply agreements with specialized substrate manufacturers in Asia and Europe.
Geographic Diversification Mandates
Government subsidies across North America and Europe are increasingly tied to back-end packaging capabilities. To secure subsidy approvals, chipmakers are establishing advanced packaging facilities adjacent to new fabrication plants, reducing geographic reliance on concentrated assembly hubs in East Asia.
