Fabless
Entities that design integrated circuits but strategically outsource manufacturing to external partners. This allows them to focus on innovation and design without the massive capital expenditure required for fabrication facilities—Qualcomm, NVIDIA, AMD
Integrated Device Manufacturers (IDMs)
Design, manufacture, assemble, test, and sell their semiconductor products across end markets. They control the entire vertical process, from chip conception to market delivery—Intel, Samsung, Micron
Foundries
Specialise in wafer-level manufacturing or fabrication, which is often highlighted as the most capital-intensive step in the entire semiconductor value chain. Foundries provide manufacturing services for chip design houses like AMD, Qualcomm, Apple, and Nvidia—TSMC, GlobalFoundries, Intel Foundry Services, and Samsung Foundry
ATMP (Assembly, Testing, Marking, and Packaging)
Specialised facilities dedicated to the crucial final stages of chip production: assembly, testing, marking, and packaging. —Micron, Renesas…
