Semiconduttori e componenti

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.

02La domanda

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.

Meccanismo

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.

Meccanismo

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.

Meccanismo

Geography concentrates risk

Advanced fabrication and assembly cluster in a few regions exposed to earthquakes, drought, power outages and geopolitical tension.

Meccanismo

Shortages hit downstream industries

Products need many chips, including mature, low-cost ones. A carenza of a single component can halt production lines far from where chips are made.

Chips sit inside the control systems of every domain.

Component supply studies are designed for the serie Strategic Systems. The European Chips Act (2023) is one of several national and regional responses to concentration in fabrication; the page names no firm.

09Questioni centrali

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?
10Meccanismi e fattori

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.

  1. 01

    Supply chain mapping

    Tracing firms and locations at each production stage. Commercial confidentiality limits visibility beyond the first tiers.

  2. 02

    Analisi delle reti

    Identifying central nodes and single points of failure using scienza delle reti. Firm-level links are often incomplete.

  3. 03

    Materials and process research

    Understanding critical inputs and alternatives using materials science and chemistry.

  4. 04

    Analisi input-output

    Estimating sector exposure to component shortages. Tables are aggregated and published with delay.

The industry changes quickly, and analyses state the date and sources of the information used.

14Domande

Domande e risposte.

Why are semiconductor supply chains fragile?
Because several steps, from equipment to advanced fabrication, are concentrated in few firms and locations, capacity takes years to build, and products depend on many chips.
What is a fab?
A semiconductor fabrication plant, where chips are manufactured on silicon wafers under strict clean-room conditions.
Do mature chips matter?
Yes. Many vehicles, appliances and industrial systems rely on older, low-cost chips, and shortages of these can halt production as much as advanced chips.
Does the platform assess individual chip makers?
No. It studies the structure of the industry and its exposures with transparent methods, not individual firms.
Are export controls analysed?
Their effects on supply structure are analysed in neutral terms. The platform does not advise on compliance.
Why do mature chips matter?
Because many essential products use them, and their shortage can stop production as effectively as a shortage of advanced chips.
