Company Overview
About Amkor Technology
Amkor Technology, Inc. is the world's second-largest provider of outsourced semiconductor assembly and test (OSAT) services, headquartered in Tempe, Arizona. Founded in 1968 by Kim Joo-jin in South Korea, Amkor packages and tests semiconductors for fabless chip designers who outsource manufacturing to foundries (TSMC, GlobalFoundries) but need their chips assembled into final packages before use. The company reported revenues of $6.1B in FY2024, down approximately 4% year-over-year due to soft consumer electronics demand.
Business Model & Competitive Advantage
Amkor's services span advanced package types including flip chip BGA, wafer-level packaging (WLP), panel-level packaging, 2.5D interposer packages (for AI chips), and 3D stacking (HBM integration). The company's advanced packaging capabilities are increasingly critical for AI: NVIDIA's H100/H200 GPUs and Blackwell architecture use CoWoS (chip-on-wafer-on-substrate) packaging that integrates HBM3 memory directly onto the GPU die — a process that relies on Amkor and ASE for outsourced packaging steps. As AI chips grow more complex and power-dense, advanced packaging is becoming a key differentiator.
Competitive Landscape 2025–2026
Amkor operates 27 manufacturing facilities across Asia (Korea, Taiwan, China, Japan, Malaysia, Vietnam, Philippines) and one new facility under construction in Peoria, Arizona — part of CHIPS Act investments to bring semiconductor packaging to the US. Amkor trades on NASDAQ (AMKR) with a market cap of approximately $5–6B. It competes primarily with ASE Technology Holding (the world's #1 OSAT), JCET Group, and Powertech Technology.
