Abstract / Overview
India crossed a symbolic threshold. At Semicon India 2025 in New Delhi on September 2, the government presented the first indigenously developed 32-bit microprocessor, Vikram, to the Prime Minister, alongside test chips from sanctioned projects. The minister in charge said five semiconductor units are under construction, one pilot line is complete, and more are nearing output. Assumption: numbers and dates reflect official statements and on-record media as of September 3, 2025.
Momentum now centers on advanced packaging, assembly, and mature-node logic, with anchor sites in Gujarat and Assam and global suppliers expanding local support. Cleanroom validation milestones at Micron’s Sanand plant and a pilot OSAT line at CG Semi signal near-term production.
Conceptual Background
India Semiconductor Mission and incentives. The Semicon India Programme allocates ₹76,000 crore across wafer fabs, OSAT/ATMP, and design. The ministry reports 23 design projects approved. Multiple sources state 10 manufacturing projects worth ~₹1.6 lakh crore have been sanctioned across states.
Vikram 32-bit processor. Designed for space-grade use by ISRO’s SCL in collaboration with VSSC, Vikram was formally presented at the 2025 event. Coverage highlights 32-bit architecture and mission-critical features.
Pilot lines and early output. The CG Semi Sanand pilot (G1) targets ~0.5 million packaged chips per day initially, with first “Made-in-India” chips expected by end-2025; commercial ramp follows post-qualification.
Anchor projects.
Dholera, Gujarat: Tata Electronics’ 300-mm fab with PSMC under government approval and technology-transfer agreements.
Jagiroad (Assam): Tata Electronics OSAT slated to begin operations in 2025.
Sanand, Gujarat: Micron ATMP entered cleanroom validation in June 2025.
Global suppliers and ecosystem. Tokyo Electron is setting up offices near Dholera and in Assam to support upcoming fabs and OSAT sites. AMD reiterated its $400 million India R&D expansion first announced in 2023; Lam and materials players such as Merck signaled deeper engagement.
Step-by-Step Walkthrough
A concise playbook for fabless firms, device OEMs, and Tier-1s to use India in 2025–2027.
Map product to facilities.
Memory and storage modules → Micron Sanand ATMP after line stabilization.
Mature-node logic, analog, and power management → package at Assam and Sanand OSAT lines; plan wafer supply via external fabs until Dholera ramps.
Stage qualification. Start with pilot lots at CG Semi G1 for package and reliability baselines, then move to higher-volume lanes. Maintain parallel production at incumbent OSATs until yields converge.
Engage on talent and vendors. Secure operator and equipment-engineer training with vendor academies and university programs highlighted around Semicon India. Track local presence of equipment suppliers near Dholera and Assam.
Lock incentives and compliance. Align PLI/DLI benefits with state packages. Maintain traceability and export-control screening across lots and modules. Use ISM/PIB guidance for milestone-based disbursals.
Roadmap to wafers. Treat Dholera as the future domestic wafer source for mature nodes; build shuttle and MPW plans via partner foundries until local wafer output starts.
Use Cases / Scenarios
Automotive electronics. Localize PMIC, MCU, and sensor ASIC packages at Assam OSAT to shorten lead times for India and ASEAN programs; qualify at Sanand for redundancy.
Consumer and PC memory. Serve domestic OEMs from Micron Sanand once production stabilizes; reserve export allocations for Middle East and EU.
Industrial/IoT and space-adjacent. Pair Vikram-class controllers for aerospace and high-reliability industrial uses with India-based packaging to prove environmental robustness and logistics speed.
Design centers at scale. Extend CPU/GPU and accelerator design teams, leveraging AMD-style India expansions and closer access to local OSAT/ATMP for evaluation boards and pilot builds.

Future Enhancements
Advanced packaging. Pilot 2.5D/3D lines as volumes scale at Assam, then standardize assembly design kits with India-based vendors.
Vendor clusters. Expand tool maker and materials footprints near Dholera and Sanand to cut service latency and spare-parts time.
MPW calendar and tapeouts. Publish a synchronized shuttle schedule for India-bound designs ahead of Dholera’s first wafers.
University pipelines. Formalize curricula for cleanroom technicians and equipment engineers tied to mission needs and supplier programs.
Conclusion
Semicon India 2025 showed tangible artifacts: a space-grade indigenous processor on stage, validated cleanrooms, and a live OSAT pilot line preparing for output. Ten sanctioned manufacturing projects and 23 funded designs point to breadth, while Dholera, Sanand, and Jagiroad anchor depth. The pragmatic route is clear: qualify packages in India now, stage mature-node silicon as Dholera ramps, and build teams aligned to vendor ecosystems. The shift from design leadership to production capability has begun, with early deliverables in sight.
