Semiconductor Fabrication Plants and India’s Chip Manufacturing Push (Dholera, Sanand)
Current Affairs & Government Schemes › Defence and Security Current Affairs · Topic 21.7
India's chip manufacturing push is led by the India Semiconductor Mission (ISM), approved by the Union Cabinet in December 2021 with an outlay of Rs 76,000 crore under the Ministry of Electronics and Information Technology. The scheme gives fiscal support of 50 percent of project cost to fabrication plants, display fabs, compound semiconductor units and assembly, test and packaging units. The main projects are the Tata Electronics and PSMC wafer fabrication plant at Dholera in Gujarat, approved in February 2024, and assembly and test plants at Sanand, including Micron Technology and CG Semi. Chips matter for defence electronics, radars, missiles and secure communication.

Where Does It Fit?
This topic links the defence macro to the electronics base. Modern missiles, radars, aircraft and communications use chips, and a secure domestic supply reduces the risk from import dependence and sanctions. Previous topic: Defence Acquisition Procedure (DAP) and Defence Procurement Reforms. Next topic: Bureau of Indian Standards (BIS) Defence Standardisation Initiatives.
What Is the India Semiconductor Mission and What Projects Are Under It?
| Project | Key facts |
|---|---|
| Tata Electronics and PSMC, Dholera | The first commercial wafer fabrication plant approved, in February 2024, with a reported investment of about Rs 91,000 crore and a capacity near 50,000 wafer starts a month. Operation was targeted in the later years of the decade, and the date has moved, as reported |
| Micron Technology, Sanand | An assembly, test, marking and packaging plant approved in June 2023. It is a back-end plant, not a wafer fab. Production was reported to have begun in early 2026 |
| CG Power with Renesas and Stars Microelectronics, Sanand | An outsourced assembly and test unit approved in February 2024, with commercial output reported in 2026 |
| Tata Semiconductor Assembly and Test, Assam | A large assembly and test plant at Jagiroad, approved in February 2024 |
| Kaynes Semicon, Sanand | An assembly and test plant approved in September 2024 and reported as inaugurated in 2026 |
| Further approvals | Units announced in 2025 and 2026 include HCL and Foxconn at Jewar in Uttar Pradesh, SiCSem and 3D Glass Solutions in Odisha, CDIL at Mohali and later additions. Counts vary by source and date |
Why Does the Chip Push Matter for Defence and the Economy?
- Strategic value: missiles, radars, electronic warfare, drones and secure radios use specialised chips, and imported chips can be denied in a crisis
- Fab versus assembly: a fabrication plant makes wafers with circuits, while an OSAT unit cuts, packages and tests them. The first is far harder and takes longer
- Government fab: the Semi-Conductor Laboratory at Mohali is a government unit that has long served strategic users, and its modernisation was proposed
- Compound semiconductors: silicon carbide and gallium-based chips are needed in radars, power systems and electric vehicles
- Design push: the Design Linked Incentive scheme supports chip design start-ups, because design talent is a strength of India
What Else Should You Remember?
- Ministry: the Ministry of Electronics and Information Technology runs the mission through an independent business division of the Digital India Corporation
- Gujarat: the state offers land, power and water support and hosts Dholera, Sanand and other projects, as reported
- Earlier attempts: earlier efforts to set up fabs in India since the 1980s did not succeed at scale
- First chip: an India-made processor, named Vikram 32-bit, by ISRO Semi-Conductor Laboratory was shown in 2025, as reported
- Link to indigenisation: chips for defence use are part of the self-reliance goals in Defence Indigenization and Atmanirbhar Bharat in Defence Production
- Component support: the Electronics Component Manufacturing Scheme, approved in 2025 as reported, supports the parts that go into boards and devices, which complements chip plants
- Challenges: ultra-pure water, steady power, trained engineers, cost gaps against Taiwan and South Korea, and long gestation
- Global setting: Taiwan makes most advanced chips and the United States, Japan and the European Union have all offered large subsidies, so India competes for projects
- Criticism: subsidy size is large, early plants are back-end, and most advanced nodes remain abroad
Why Does It Matter for the Exam?
- Mission facts: ISM year, outlay and 50 percent support
- Fab and OSAT: which project is a wafer fab and which is assembly and test
- Locations: Dholera and Sanand in Gujarat, Jagiroad in Assam
- Agency: MeitY and the Digital India Corporation
- Common errors: calling Micron a fabrication plant, or placing Dholera in Maharashtra
As an analytical point, chip self-reliance is a long game. Assembly plants build skills quickly, but a secure supply for defence needs wafer fabs, materials, equipment and design talent working as one ecosystem.

Frequently Asked Questions
What is the India Semiconductor Mission?
The India Semiconductor Mission is a programme approved by the Union Cabinet in December 2021 with an outlay of Rs 76,000 crore to build a chip manufacturing and display ecosystem. It is run by the Ministry of Electronics and Information Technology and offers 50 percent fiscal support on project cost.
What is the difference between a fab and an OSAT plant?
A fabrication plant, or fab, makes the wafer with circuits through complex chemical and optical steps. An OSAT plant takes finished wafers and cuts, packages and tests the chips. Fabs need far larger investment and skills, while assembly and test plants are easier to set up.
Where is the Tata Electronics semiconductor fab located?
The Tata Electronics and PSMC fabrication plant is at Dholera in Gujarat. It was approved in February 2024 with a reported investment of about Rs 91,000 crore and a capacity of about 50,000 wafer starts a month. Its start date has moved later, so treat timelines as targets.
What is the role of Micron at Sanand?
Micron Technology is building an assembly, test, marking and packaging plant at Sanand in Gujarat, approved in June 2023. It is a back-end plant and not a wafer fab. Reports said that production began in early 2026, though exact dates differ between sources.
Why do semiconductors matter for defence?
Missiles, radars, drones, aircraft and secure radios all depend on chips, including specialised ones. Reliance on imports risks denial in a crisis, so domestic production and trusted supply lines improve readiness. Compound semiconductors such as gallium-based chips are important for radar and power systems.
