17 companies in the Foundry part of the semiconductor & AI value chain — Pure-play foundries manufacture chips designed by others, enabling the fabless model. TSMC is the world's leading logic foundry — it manufactures the most advanced nodes and produces chips for most of the largest fabless companies, making it arguably the single most strategically important company in the supply chain. Samsung also offers foundry services and is a key alternative for leading-edge logic. Specialized foundries such as Win Semiconductors (GaAs RF), GlobalFoundries, UMC, and SMIC serve the much larger market for mainstream and specialty nodes.
