22 companies in the IDM part of the semiconductor & AI value chain — Integrated device manufacturers design, fabricate, and sell chips under one roof — the traditional vertically integrated model. IDMs trade manufacturing flexibility for process control and captive capacity, which is a strategic advantage in analog, power, and image sensing where proprietary process nodes differentiate products. Texas Instruments and Analog Devices lead analog; Sony leads in CMOS image sensors; Infineon leads power semiconductors; Samsung participates here as both the world's largest memory IDM and a logic foundry.
