Global semiconductor foundries face acute capacity bottlenecks in advanced packaging technologies, threatening to delay the deployment of high-performance artificial intelligence chips through late 2025.
Packaging Constraints Limit Yields
Leading silicon manufacturers are operating at near-100 percent utilization for Chip-on-Wafer-on-Substrate packaging. Industry analysts report that while raw wafer fabrication remains stable, the downstream assembly required for high-bandwidth memory integration cannot meet enterprise order volumes. This bottleneck has extended lead times for tier-one cloud providers to over 40 weeks.
CapEx Reallocation to Advanced Assembly
In response, major foundries are shifting capital expenditure from traditional node scaling to advanced packaging facilities. Market projections indicate specialized packaging capacity will expand by 65 percent year-over-year, though market equilibrium is unlikely before Q3 2025.
