Semiconductors are made through a long value chain of design, specialised materials, manufacturing equipment, fabrication and assembly, with several steps concentrated in a few firms and places. Shortages can stall vehicles, medical devices and infrastructure. This page sets out how the chip value chain is structured, where it concentrates, how disruptions propagate, and what evidence serves the governments and industries that depend on it.
Semiconductors and components in seven parts.
Semiconductors and components: how the risk develops.
Electronics, advanced materials and fabrication inputs. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Each step is specialised
Design tools, wafers, speciality gases and chemicals, lithography equipment, fabrication and packaging are each dominated by few suppliers. A bottleneck at any step limits output.
Fabs take years and vast capital
Leading fabrication plants cost billions and take years to build. Capacity cannot be added quickly when demand changes or supply is disrupted.
Geography concentrates risk
Advanced fabrication and assembly cluster in a few regions exposed to earthquakes, drought, power outages and geopolitical tension.
Shortages hit downstream industries
Products need many chips, including mature, low-cost ones. A 부족 of a single component can halt production lines far from where chips are made.

What experts ask about semiconductor supply.
- At which stages of the chain is capability concentrated in few firms or locations?
- Which specialised inputs, such as high-purity gases, chemicals and wafers, are single-sourced?
- How long would it take to replace lost fabrication capacity?
- Which downstream sectors are most exposed to shortages of mature or advanced chips?
- How do export controls and industrial policies change the structure of the chain?
Why the chain is fragile.
Semiconductor manufacturing requires extreme precision, very large capital investment and accumulated know-how. Leading-edge fabrication plants take years to build and need specialised equipment from a handful of suppliers. These barriers favour concentration: each stage tends to have few capable players, and the stages are spread across different regions.
Shortages propagate widely because chips are embedded in so many products. Even inexpensive, mature-node chips can halt the production of much more valuable goods when they are missing. Long lead times and the difficulty of switching suppliers, since chips must be qualified for each product, slow recovery.
Other components share similar features: specialised capacitors, displays, sensors and advanced materials often depend on few producers and on inputs such as rare gases or high-purity minerals.
