India Semiconductor Manufacturing 2026: Fabs, OSAT, and the Supply Chain Opportunity
Introduction
In 2026, India’s semiconductor ambition has moved from policy document to construction site to operational facility. Micron’s OSAT plant in Sanand, Gujarat is packaging and testing DRAM and NAND chips. Tata Electronics’ semiconductor assembly and test facility in Jagiroad, Assam is operational. CG Power’s OSAT facility in Sanand is coming online. The Tata wafer fabrication facility in Dholera is in advanced construction. India is no longer a semiconductor aspiration – it is a semiconductor supply chain destination.
This article explains what is actually operational in 2026, what the capability boundaries are, what is coming in 2027-2028, and what it means for global electronics supply chains.
What Is Operational in India in 2026
Micron Technology – Sanand, Gujarat (OSAT)
Micron’s $2.75B OSAT (Outsourced Semiconductor Assembly and Test) facility began volume production in late 2025. The facility assembles and tests DRAM and NAND flash memory chips for global markets. At full ramp, it handles assembly, packaging, wafer probe, final test, and burn-in for memory devices destined for data centre, automotive, and consumer electronics applications.
Capability: Memory device OSAT only – DRAM and NAND. Not a logic or mixed-signal foundry. Capacity: ~450,000 wafer starts per month equivalent at full ramp. Strategic significance: This is the first major US semiconductor company to establish manufacturing in India.
Tata Electronics – Jagiroad, Assam (OSAT)
Tata’s first semiconductor facility, built in partnership with Powerchip Semiconductor Manufacturing Corporation (PSMC) of Taiwan, is operational for packaging and testing. The facility handles wafer bumping, flip-chip packaging, and test for mature-node logic chips and display drivers.
Capability: Mature-node chip packaging and test (28nm and above). Not a leading-edge logic fab. Capacity: Initial phase handling mid-tier volumes, ramping through 2026.
CG Power – Sanand, Gujarat (OSAT)
CG Power’s facility, developed in partnership with Renesas (Japan) and Stars Microelectronics (Thailand), focuses on automotive-grade and industrial semiconductor packaging. The facility targets IATF 16949-qualified automotive chip production – a critical gap given the 2021-2023 automotive chip shortage.
Capability: Automotive and industrial chip packaging (AEC-Q100 qualified). This is a strategically important capability differentiation.
The Dholera Fab: India’s First Wafer Fabrication Plant
Tata’s greenfield semiconductor wafer fabrication facility in Dholera Special Investment Region (Gujarat) – developed with PSMC – is under construction with first silicon expected in 2026-2027. Key parameters:
- Node: 28nm and above (mature node) – not cutting-edge sub-5nm
- Wafer size: 300mm
- Target capacity: 50,000 wafer starts per month at full ramp
- Target markets: Automotive ICs, power management, display drivers, microcontrollers, IoT devices
- Investment: Rs 91,000 Cr (approximately $11B) with India Semiconductor Mission support
Strategic context: 28nm is the sweet spot for automotive, industrial, and consumer IoT applications. It is not competing with TSMC’s 3nm for AI chips – it is building India’s base in the semiconductor supply chain for the product categories India actually manufactures: cars, phones, industrial equipment.
What India’s Semiconductor Capability Means for Global Supply Chains in 2026
For Memory-Dependent Products: Immediate Benefit
Companies sourcing DRAM and NAND memory for products sold in the US or Europe can now specify India-origin packaging (Micron Sanand) to satisfy supply chain resilience and domestic content requirements. This is relevant for data centre equipment buyers, automotive electronics OEMs, and consumer electronics assemblers.
For Automotive Electronics: Emerging Benefit
CG Power’s Renesas-aligned OSAT provides AEC-Q100 qualified packaging for automotive chips. Companies building EV powertrains, ADAS systems, or vehicle body electronics who need to diversify away from Taiwan-concentrated automotive IC packaging have a new India option in 2026.
For Logic-Intensive Products (AI, High-Performance Computing): Not Yet
India has no leading-edge logic fab (sub-7nm). For AI accelerators, GPUs, and advanced mobile SoCs, TSMC Taiwan, Samsung Korea, and Intel Foundry remain the only options. India will not have leading-edge logic capability before 2030+ at the earliest.
The India Semiconductor Mission: Policy Support Through 2027
The India Semiconductor Mission (ISM) has committed Rs 76,000 Cr (approximately $9B) across three scheme windows:
- Scheme A (Fab): 50% fiscal support for wafer fabrication facilities. Tata Dholera is the first beneficiary.
- Scheme B (OSAT/ATMP): 50% fiscal support for assembly, testing, marking, and packaging. Micron, Tata, and CG Power are beneficiaries.
- Scheme C (Compound Semiconductors/MEMS): 50% fiscal support for specialty semiconductor manufacturing. Several companies in advanced discussions.
The ISM has disbursed approximately Rs 18,000 Cr as of early 2026, with the remaining committed as facilities hit production milestones. The fiscal commitment is real and disbursed – not aspirational.
ECMS 2025 and the Component Ecosystem Around Semiconductors
The Electronics Component Manufacturing Scheme (ECMS 2025, Rs 22,919 Cr) targets the upstream component supply chain that semiconductor manufacturing requires: PCB substrates, advanced packaging materials, test socket components, and speciality chemicals. Several tier-1 component manufacturers from Japan, South Korea, and Taiwan have filed expressions of interest to establish India manufacturing under ECMS, attracted by PLI incentives and proximity to India’s growing semiconductor assembly base.
Key Takeaways
- India has operational OSAT capability in 2026: Micron (memory), Tata Electronics (logic/display), and CG Power (automotive) are all producing.
- Wafer fabrication (Tata Dholera, 28nm) is expected to yield first silicon in 2026-2027 – India is months, not years, away from domestic chip production.
- India’s semiconductor capability is strongest in memory packaging, automotive-grade chips, and mature-node logic – the products that India’s growing electronics manufacturing base actually needs.
- For leading-edge logic (AI chips, advanced mobile SoCs), India is not yet a supply option.
- The India Semiconductor Mission’s Rs 76,000 Cr fiscal commitment is disbursing against production milestones – the money is real.
FAQ
Q: Can I source chips from India for my product in 2026?
A: For memory chips (DRAM, NAND): yes, Micron Sanand output. For automotive ICs (AEC-Q100): yes, CG Power Sanand. For general logic/microcontrollers from India-origin wafer fab: expected 2027+. For cutting-edge logic: not India in the foreseeable future.
Q: What does “OSAT” mean and how does it differ from a foundry?
A: A semiconductor foundry (like TSMC) fabricates chips from silicon wafers – it does the complex photolithography that creates transistors. An OSAT (Outsourced Semiconductor Assembly and Test) facility receives finished wafers from a foundry, cuts them into individual chips (dicing), packages them in protective housings, and tests them. India has OSAT facilities now; its first foundry is under construction.
Q: How does India semiconductor manufacturing interact with PLI for electronics?
A: India-origin components (including packaged semiconductors) can count toward domestic value addition requirements under PLI schemes, potentially increasing PLI incentives for electronics OEMs who source from Indian OSAT facilities. ECMS 2025 creates additional incentives for OSAT output consumed domestically.
