SEMICON India 2026 opens today, 17 September, at Yashobhoomi in Dwarka, New Delhi, and runs to 19 September. It is the country’s biggest semiconductor event, and it lands at a moment when India has gone from making no chips at all to having plants in commercial production. This explainer says, in very plain words, what a semiconductor actually is, why building a chip factory is so extraordinarily hard, and the facts most likely to be asked in SSC CGL and CHSL, RRB NTPC, banking general awareness, UPSC and State PSC.
What a Semiconductor Actually Is
Start with the word, because it explains itself once you slow down.
Some materials conduct electricity — copper, aluminium. Some do not — rubber, glass. A semiconductor sits in between: silicon, mostly, which is refined sand. On its own it is a poor conductor. But if you add tiny, carefully chosen impurities, you can make it conduct sometimes — and that is the whole trick.
A material that conducts only when you tell it to is a switch. Put billions of those switches on one fingernail-sized piece of silicon and you have a chip. Every calculation your phone does is those switches flicking between on and off.
So a chip is not a component like a battery or a screen. It is the thinking part. A car has dozens. A phone has several. A missile, a power grid, a hospital scanner and an ATM all depend on them. That is why a country with no chip factory is not merely importing a product — it is renting its ability to think.
Why Building a Chip Factory Is So Hard
This is the part that explains every policy decision that follows, and it is worth a minute.
- The features are unimaginably small. A modern chip has details measured in nanometres — a nanometre is a billionth of a metre, and a human hair is roughly 80,000 of them wide. You are carving patterns far too small to see with any ordinary microscope.
- A single speck of dust ruins a chip. Fabs are built as cleanrooms far cleaner than an operating theatre, with filtered air and workers in full-body suits — not for the workers’ safety, but for the silicon’s.
- The machines cost more than aeroplanes. The equipment that prints these patterns is made by a handful of companies in the world, and a single machine can cost more than a commercial jet.
- It takes years and vast money before the first chip is sold. A fab is a multi-billion-dollar bet placed several years before any revenue arrives.
Put those four together and you have the reason India had no fab for decades. It was never a lack of engineers — India designs a very large share of the world’s chips. It was that designing a chip needs clever people and computers, while making one needs a cleanroom, a decade and a mountain of capital. India had the first and not the second.
The India Semiconductor Mission
| Feature | Detail |
|---|---|
| Launched | December 2021, with an outlay of ₹76,000 crore. |
| Ministry | Ministry of Electronics and Information Technology (MeitY). The India Semiconductor Mission (ISM) runs it. |
| The main lever | A capital subsidy of up to 50 per cent of project cost. The government pays down the mountain, because no company would climb it alone. |
| Progress | 12 projects approved under the first phase, with three already in commercial production. |
| Next phase | Semicon 2.0 has been announced, built on six pillars to widen the ecosystem beyond manufacturing alone. |
| Design support | 332 academic institutes and 105 start-ups given access to chip-design tools; 24 start-ups approved under the Design Linked Incentive scheme. |
The Projects Worth Knowing by Name
| Project | Where | Who |
|---|---|---|
| Wafer fabrication plant — India’s first commercial fab, at the 28 nanometre node | Dholera, Gujarat | Tata with PSMC of Taiwan |
| Assembly and testing (ATMP) | Sanand, Gujarat | Micron |
| Assembly and testing (OSAT) | Sanand, Gujarat | CG Power with Renesas |
| Assembly and testing | Jagiroad, Assam | Tata Electronics |
| Assembly and testing | Sanand, Gujarat | Kaynes Technology |
| Display-driver chips | Jewar, Uttar Pradesh | HCL with Foxconn |
The distinction examiners love: a fab actually makes the chip on a silicon wafer. ATMP and OSAT take finished wafers and do the assembly, testing, marking and packaging — cutting them up, wiring them and sealing them into the black rectangles you see on a circuit board. Most of India’s approved projects are packaging plants; Dholera is the one true fab. That is not a criticism — packaging is where almost every chip-making country starts.
What SEMICON India 2026 Is
- The fifth edition of the event, organised jointly by the India Semiconductor Mission and SEMI, the global industry association.
- Held at Yashobhoomi — the India International Convention and Expo Centre in Dwarka, New Delhi — from 17 to 19 September 2026.
- Theme: “Silicon to Systems: Building the Ecosystem”. The phrase is the policy in four words — the aim is no longer just to make silicon, but to build everything around it.
- Scale: more than 500 exhibitors, 240+ international companies, 150+ speakers and delegations from over 40 countries.
Why the World Suddenly Cares
Chips became a geopolitical subject rather than an industrial one for a simple reason: almost all of the most advanced ones are made in very few places. When supply chains broke during the pandemic, car factories across the world stopped — not for want of steel or workers, but for want of chips costing a few rupees each.
Every large economy drew the same conclusion: a country that cannot make chips can be switched off by someone else’s decision. That is why India, the United States, the European Union and Japan all announced chip programmes within a few years of each other.
Officials project global semiconductor demand roughly doubling from about $1 trillion to $2 trillion, with India’s own demand rising from around $100 billion to $200 billion. Treat projections as projections — they are estimates of the future, not measurements of the present, and a careful answer says so.
The link to the rest of the economy is direct. Electronics assembly under schemes such as the Mobile Phone Manufacturing Scheme currently imports the chips it puts inside Indian-made phones. Making them here is what turns assembly into manufacturing — and that shift is part of the growth story we cover in our explainer on India’s GDP numbers.
Practice Questions
Q1. The India Semiconductor Mission was launched in December 2021 with an outlay of:
(a) ₹10,000 crore (b) ₹76,000 crore (c) ₹1.5 lakh crore (d) ₹25,000 crore
Answer: (b) ₹76,000 crore ₹76,000 crore, under the Ministry of Electronics and Information Technology. The mission offers a capital subsidy of up to 50 per cent of project cost.
Q2. India’s first commercial semiconductor fabrication plant is coming up at:
(a) Sanand, Gujarat (b) Jagiroad, Assam (c) Dholera, Gujarat (d) Jewar, Uttar Pradesh
Answer: (c) Dholera, Gujarat Dholera in Gujarat, a Tata project with PSMC of Taiwan, at the 28 nanometre node. Sanand, Jagiroad and Jewar host assembly, testing and packaging plants — which is a different stage of the process.
Q3. What is the difference between a fab and an ATMP unit?
(a) A fab tests chips; an ATMP designs them (b) A fab makes the chip on a wafer; an ATMP assembles, tests and packages it (c) They are two names for the same thing (d) A fab handles only memory chips
Answer: (b) A fab makes the chip on a wafer; an ATMP assembles, tests and packages it The fab creates the circuitry on silicon. ATMP and OSAT plants take finished wafers and cut, wire, package and test them. Most countries begin with packaging and move to fabrication later.
Q4. SEMICON India 2026 is being held at Yashobhoomi, New Delhi, on the theme:
(a) Make in India, Made for the World (b) Silicon to Systems: Building the Ecosystem (c) Chips for a Digital Bharat (d) Atmanirbhar Semiconductors
Answer: (b) Silicon to Systems: Building the Ecosystem “Silicon to Systems: Building the Ecosystem” — the phrase signals a shift from making silicon alone to building design, packaging, materials and talent around it.
Q5. Why is a semiconductor useful in electronics?
(a) It conducts electricity better than copper (b) It never conducts electricity (c) It can be made to conduct only under certain conditions, so it acts as a switch (d) It stores electricity like a battery
Answer: (c) It can be made to conduct only under certain conditions, so it acts as a switch That controllability is the point. A material that conducts only when told to is a switch, and billions of switches on one piece of silicon make a chip. Copper conducts always, and rubber never — neither can compute.
Common Mistakes to Avoid
- Calling every approved project a “chip factory”. Most are packaging and testing plants. Dholera is the fab.
- Putting the mission under the wrong ministry. It is MeitY, not the Ministry of Heavy Industries or Commerce.
- Saying India had no semiconductor capability before 2021. India has long been strong in chip design; what it lacked was manufacturing.
- Quoting market projections as current figures. The $2 trillion number is a forecast, not today’s market size.
- Confusing nanometre nodes with chip size. A smaller node number means finer circuitry, not a smaller chip.
- Treating project counts as fixed. New approvals are announced regularly — learn the mission’s structure and check the current count before an exam.
