About
ASE Technology Holding is the world's largest semiconductor packaging and testing company (OSAT), formed in 2018 through the combination of Taiwan's ASE Group and Siliconware Precision Industries (SPIL). Headquartered in Kaohsiung, Taiwan, the group employs about 70,000 people and generates annual revenue of roughly US$19 billion, packaging and testing chips for virtually every major semiconductor company.\n\nASE's core business transforms bare silicon wafers into finished, tested chips: wire bonding, flip-chip, system-in-package (SiP), and advanced 2.5D/3D packaging that integrates multiple dies into a single module. This 'back-end' manufacturing is increasingly the performance bottleneck of the AI era — advanced packaging like ASE's FOCoS and fan-out technologies enables the high-bandwidth memory stacks used in AI accelerators. The group operates plants in Taiwan, China, Malaysia, Japan, and the United States, and has invested heavily in automotive-grade packaging through its subsidiary, serving the growing chip content of electric vehicles.\n\nFor the semiconductor supply chain, ASE is the essential partner between chip designers and end products: its scale in packaging, testing, and materials procurement (lead frames, substrates, mold compounds) makes it one of the largest buyers of semiconductor materials in Asia and a critical node in electronics manufacturing worldwide.
