Global chipmakers are increasingly looking beyond traditional transistor scaling to sustain performance growth. As sub-2nm fabrication costs surge, advanced packaging technologies have emerged as the primary battlefield for competitive advantage in high-performance computing.
Capital Reallocation to 2.5D and 3D Integration
Foundries are shifting capital expenditure toward advanced packaging solutions like chiplets and high-density interconnects. This architectural pivot allows manufacturers to combine disparate process nodes into a single system-in-package, optimizing both yield and cost-efficiency for artificial intelligence workloads.
Supply Chain Bottlenecks and Outlook
Despite rapid adoption, capacity constraints in substrate manufacturing and silicon interposers remain a near-term bottleneck. Industry analysts project packaging investments will outpace front-end equipment spending through 2026 as market demand stabilizes.
