Extreme specialization across design, fabrication, and equipment concentrates capability at a few critical nodes, where the narrowing of participants at each stage creates both extraordinary pricing power and systemic fragility.
How extreme specialization across design, fabrication, and equipment creates a supply chain where concentration at key nodes produces both extraordinary returns and systemic fragility.
Introduction
The semiconductor supply chain is defined by extreme specialization — no single company performs all the functions required to produce a chip. Design, fabrication, equipment manufacturing, materials supply, and packaging are each performed by different companies, and at several of these nodes, the number of capable participants has narrowed to one or two. ASML alone supplies the lithography equipment needed for leading-edge chips. TSMC fabricates the majority of advanced processors. This concentration creates extraordinary returns for the occupants and systemic fragility for everyone who depends on them.
Understanding this supply chain structurally means examining how specialization creates interdependence, how concentration at critical nodes produces pricing power and vulnerability simultaneously, and why capacity cannot adjust quickly to demand — creating the cycles of shortage and surplus that ripple through the global economy.
Core Business Model
Position in the supply chain determines a company's economics more than anything else. Design companies invest primarily in R&D and people, requiring modest capital but producing high margins. Foundries invest tens of billions in fabrication facilities, earning manufacturing fees with capital intensity that few industries match. Equipment makers sell the machines that foundries depend on, and at the leading edge, some of these positions are monopolies.
The chain divides into distinct segments: design companies (like Nvidia, Qualcomm, AMD) create chip architectures; foundries (like TSMC, Samsung) manufacture them; equipment makers (like ASML, Applied Materials) build the machines; materials companies provide the substances; and packaging firms prepare finished chips for use in devices.
The economic engine is technological advancement. Each generation of chips becomes smaller, faster, and more efficient. This progress requires continuous investment by all participants. Companies that fail to keep pace become irrelevant; those that lead capture disproportionate value. The industry's velocity creates both opportunity and risk.
