One processor. Many countries. Hundreds of specialists. How the semiconductor industry coordinates a global manufacturing network.
A modern chip may be designed in one country, fabricated in another, combined with memory from a third, packaged somewhere else and finally installed in a product assembled on the other side of the world. A single advanced product can involve 50 to 100 or more companies across materials, tools, design, manufacturing and assembly.
This is not an exception. It is how much of the semiconductor industry works.
To understand why, we need to look at the geography of specialisation.
1. Different regions developed different strengths
The semiconductor ecosystem is global, but some regions have become especially important in particular capabilities.
| Region | Important strengths | Examples |
|---|---|---|
| United States | Chip design, EDA, equipment, IP | NVIDIA, AMD, Qualcomm, Synopsys, Cadence, Applied Materials, Lam Research, KLA |
| Taiwan | Foundries, wafer manufacturing, packaging | TSMC, UMC, ASE |
| South Korea | Memory, foundries, electronics | Samsung, SK hynix |
| Japan | Silicon wafers, photoresists, chemicals, equipment | Shin-Etsu, SUMCO, JSR, TOK, Tokyo Electron, Nikon, SCREEN |
| Netherlands | Advanced lithography | ASML |
| Germany | High-precision optics, materials and equipment | ZEISS, Siltronic |
| China | Refining and processing key minerals (gallium, germanium, rare earths), manufacturing, equipment and a large domestic chip ecosystem | SMIC and many materials and equipment companies |
| India | Chip design talent, emerging fabs, assembly and testing | Tata Electronics, Micron, CG Semi, Kaynes and design centres |
This is a broad map, not a claim that each region does only one job. Companies operate internationally and supply chains cross borders.
Some dependencies sit far upstream. China dominates the refining of gallium and germanium — metals used in specialised semiconductors — and much of the world’s rare-earth processing, which is why these materials now feature prominently in trade and export-control discussions.
2. Why does Taiwan matter so much?
Taiwan is central to advanced foundry manufacturing, especially through TSMC.
A fabless company can design a chip and contract a foundry to manufacture it. But the foundry must have the process technology, production capacity, engineering capability and yield performance required by that product.
TSMC’s role is therefore much more than owning buildings. It has decades of process knowledge, supplier relationships, manufacturing data and customer collaboration.
The concentration of advanced manufacturing in a small number of companies and locations is also a supply-chain risk. A disruption can affect industries worldwide.
3. Follow one AI accelerator through the network
Consider a high-end AI accelerator.
- The chip company defines the architecture and designs the processor.
- EDA tools help engineers verify and implement the design.
- The foundry’s process design rules shape the physical layout.
- The foundry fabricates the compute dies on silicon wafers.
- Memory manufacturers supply high-bandwidth memory stacks.
- Advanced packaging integrates compute and memory.
- Test and assembly partners validate the package and build the final component.
- System manufacturers install it into accelerator boards, servers and racks.
NVIDIA’s public filings describe its use of foundries including TSMC and Samsung for wafer manufacturing, memory suppliers including SK hynix, Micron and Samsung, and CoWoS packaging technology. The exact route varies by product. NVIDIA SEC filing.
4. Why this is not just a purchasing exercise
A semiconductor company cannot simply buy any wafer, chemical or machine from any supplier.
Materials and tools must be qualified for the process. A change in a chemical, gas, photoresist or equipment component can affect yield and reliability.
Suppliers work closely with customers on:
- Process qualification.
- Reliability and defect control.
- Capacity planning.
- Engineering changes.
- Delivery schedules.
- Traceability and quality systems.
A disruption deep in a supplier’s own supply chain can affect production months later. The industry’s complexity extends far beyond the names printed on a purchase order.
5. India’s role: from design services to manufacturing ecosystem
India has long been important in semiconductor design and engineering. The next step is to expand domestic manufacturing capabilities.
The opportunity includes several distinct layers:
- Design: architecture, RTL, verification, physical design and embedded systems.
- Wafer fabrication: building transistors on silicon wafers.
- ATMP/OSAT: assembly, testing, marking and packaging.
- Compound semiconductors: materials such as silicon carbide and gallium nitride.
- Equipment and materials: specialised tools, chemicals and components.
- Research and talent: universities, labs, process engineers and manufacturing skills.
The government’s Semicon India Programme has approved projects across silicon fabrication, compound semiconductors and packaging. In an April 2026 government update, India reported ten approved projects with planned investment of about ₹1.6 lakh crore. Press Information Bureau, 1 April 2026.
Examples include:
- Tata Electronics with PSMC — silicon fab project at Dholera, Gujarat.
- Micron — memory assembly and test facility at Sanand.
- Tata Semiconductor Assembly and Test — Assam.
- CG Power with Renesas and Stars Microelectronics — OSAT in Gujarat.
- Kaynes Semicon — OSAT in Gujarat.
- HCL and Foxconn — semiconductor project in Uttar Pradesh.
- SiCSem — silicon carbide project in Odisha.
- 3D Glass Solutions — advanced packaging in Odisha.
- CDIL — discrete semiconductor manufacturing in Punjab.
- ASIP — assembly and packaging in Andhra Pradesh.
A crucial distinction: approval, construction, pilot production and commercial production are different milestones. A proposed fab should not be described as an operational high-volume fab. The status of each project must be checked against current company and government disclosures.
India’s first big challenge is not simply to announce factories. It is to build the suppliers, process expertise, reliable utilities, skilled workforce and customer relationships that allow those factories to run competitively.
6. The next semiconductor race
The industry is expanding because demand for computing is rising across AI, data centres, phones, cars, industrial systems, defence and space.
Tesla and SpaceX’s Terafab initiative is one example of companies seeking greater control over future chip supply. SpaceX announced in August 2026 that Terafab would be built in Grimes County, Texas, with a plan to combine logic, memory and advanced packaging. It remains a major planned manufacturing effort, not an established commercial foundry. SpaceX update.
The next phase of competition will involve not only smaller transistors, but also:
- Advanced packaging.
- High-bandwidth memory.
- Chiplets.
- Power efficiency.
- Manufacturing resilience.
- Materials and equipment capacity.
- Skilled people and process knowledge.
The takeaway
The semiconductor industry is a global system of interdependence.
No single company or country has every capability. Design, materials, equipment, wafer fabrication, memory, packaging and system integration have evolved into highly specialised fields.
India’s opportunity is to build meaningful capability across more of these layers, while connecting to the global ecosystem.
The world’s most advanced chips are not just products of silicon. They are products of collaboration, specialisation and industrial coordination.
