ASE is a major semiconductor assembly and advanced-packaging provider, with FOCoS, FOCoS-Bridge, CoWoS, system-in-package and FC-BGA capabilities for AI and HPC applications.

Positioning

ASE Technology Holding is a Taiwan-based public OSAT and advanced-packaging provider, positioned among the largest global independent assembly-and-test suppliers and a major alternative to in-house foundry packaging. Its domain activity accelerated through a February-2025 Penang plant launch, May-2025 FOCoS-Bridge-with-TSV technology announcement, October-2025 NT$17.6 billion K18B advanced-packaging factory groundbreaking, May-2026 310mm panel-level packaging line announcement, and May-2026 Analog Devices facility acquisition. ASE supplies or works with named ecosystem participants including NVIDIA through subsidiary SPIL, AMD, Analog Devices and WUS; the open question is how much of its broad packaging revenue is directly attributable to AI accelerators rather than general semiconductor demand.
