According to IDC’s Worldwide Semiconductor Supply Chain Tracking Intelligence latest report, the global semiconductor market, following a recovery in 2024, is expected to experience steady growth in 2025. The broadly defined Foundry 2.0 market— encompassing foundry, non-memory IDM, OSAT, and photomask making—is projected to reach a market size of $298 billion in 2025, with year-over-year growth of 11%, signaling a transition from a recovery phase in 2024 to a growth phase in 2025. Over the long term, the compound annual growth rate (CAGR) from 2024 to 2029 is projected to reach 10%. This growth is catalyzed by the continuous rise in AI demand and a gradual recovery in non-AI demand.
