India's Semiconductor Fab Timeline: 3 Projects, 2 Delays, 1 Might Work

India's push for semiconductor manufacturing gained significant momentum with the India Semiconductor Mission (ISM) launched in December 2021. This initiative aims to establish a robust ecosystem for chip design, manufacturing, and packaging within the country. Despite substantial financial incentives, the journey has been marked by ambitious announcements, subsequent delays, and a recent breakthrough.

The Policy Framework: India Semiconductor Mission (ISM)

The ISM was approved with an outlay of approximately ₹76,000 crore (around $10 billion at the time) to attract global players. The mission focuses on creating a comprehensive ecosystem, not just isolated manufacturing units. This includes support for silicon fabrication (fab) units, display fabs, compound semiconductors, packaging (ATMP/OSAT), and design-linked incentives (DLI).

Key Components of the ISM

• Scheme for Setting up Semiconductor Fabs: Financial support for establishing silicon-based semiconductor fabs. The scheme offers fiscal support of up to 50% of the project cost.
• Scheme for Setting up Display Fabs: Similar financial support for display manufacturing units.
• Scheme for Setting up Compound Semiconductors/Silicon Photonics/Sensors Fabs and Semiconductor ATMP/OSAT Units: Incentives for specialized manufacturing and packaging.
• Design Linked Incentive (DLI) Scheme: Encourages domestic companies, startups, and MSMEs to undertake semiconductor design.

This multi-pronged approach reflects a recognition that a fragmented effort would not yield the desired results. The incentives are designed to offset the high capital expenditure and technological complexities inherent in semiconductor manufacturing.

Project 1: Vedanta-Foxconn JV (Delayed)

The initial high-profile announcement came in September 2022, with a joint venture between Vedanta and Taiwanese electronics giant Foxconn. The proposed investment was substantial, aiming for a 28nm semiconductor fab and a display manufacturing unit in Dholera, Gujarat.

• Original Plan: Establish a 28nm fab and a display fab.
• Proposed Location: Dholera Special Investment Region, Gujarat.
• Timeline: Initial target for production by 2027.

Challenges and Separation

The Vedanta-Foxconn partnership faced scrutiny regarding its technological readiness and financial viability. Foxconn, a contract manufacturer, lacked direct experience in advanced chip fabrication. Vedanta, primarily a mining conglomerate, also had no prior semiconductor manufacturing background.

• Technology Transfer: The critical element of securing a suitable technology partner for the 28nm process proved challenging.
• Financial Commitments: Questions arose about the JV's ability to meet the stringent financial and technical criteria for government incentives.

In July 2023, Foxconn announced its withdrawal from the joint venture, citing a need for "diversification of development strategies." This marked a significant setback, highlighting the complexities of attracting and retaining high-tech manufacturing partners. Vedanta subsequently stated its commitment to proceed independently, securing a new technology partner.

Project 2: IGSS Ventures (Delayed)

Singapore-based IGSS Ventures was another early applicant under the ISM, proposing a 28nm fab in Tamil Nadu. Their proposal focused on specialized applications, including automotive and industrial chips.

• Original Plan: Establish a 28nm fab.
• Proposed Location: Tamil Nadu.
• Focus: Niche applications like automotive and industrial semiconductors.

Status and Hurdles

IGSS Ventures' application faced delays in meeting the technical and financial criteria set by the ISM. While their proposal was initially considered, progress stalled. The government's stringent evaluation process aims to ensure that only serious and capable players receive the substantial fiscal support.

• Technical Due Diligence: The ISM conducted thorough technical evaluations of all proposals, requiring detailed roadmaps for technology acquisition and manufacturing.
• Funding Assurance: Applicants needed to demonstrate clear funding sources and financial closure plans.

As of early 2024, the IGSS Ventures project has not moved forward significantly, indicating that securing both technology and funding remains a considerable hurdle for new entrants in the fab space. This demonstrates the rigorous vetting process for projects seeking government support, as discussed in the context of India's Export Competitiveness: Economic Policy & Industrial Transformation.

Project 3: Tata-PSMC (Operational Prospects)

The most promising development has been the Tata Electronics-Powerchip Semiconductor Manufacturing Corp. (PSMC) joint venture. In February 2024, the Union Cabinet approved the establishment of India's first commercial semiconductor fab by this JV in Dholera, Gujarat.

• Technology Partner: Taiwan's PSMC, a pure-play foundry with established expertise.
• Process Node: 55nm, 40nm, 28nm.
• Investment: Approximately ₹91,000 crore (around $11 billion).
• Capacity: 50,000 wafers per month.

Why This Project Might Work

Several factors differentiate the Tata-PSMC venture from previous attempts:

1. Experienced Technology Partner: PSMC brings proven expertise in wafer fabrication, a critical component missing in earlier proposals. Their experience reduces technological risk.
2. Diverse Process Nodes: Offering multiple process nodes (55nm, 40nm, 28nm) allows for a wider range of applications, including power management ICs, display drivers, and automotive chips, which are in high demand globally.
3. Tata Group's Commitment: The Tata Group's financial strength and long-term vision provide stability and credibility to the project. Their commitment extends beyond just the fab to include an ATMP (Advanced Packaging) unit in Morigaon, Assam, with an investment of ₹27,000 crore.
4. Government Support: The project receives 50% fiscal support from the central government and additional incentives from the Gujarat state government.

This project represents a significant step towards India's goal of semiconductor self-reliance. The focus on established, albeit not bleeding-edge, technology nodes is a pragmatic approach to building foundational capabilities before attempting more advanced nodes.

Comparative Analysis of Semiconductor Fab Projects

This comparison highlights the importance of a credible technology partner and a clear financial roadmap in securing government approval and progressing towards implementation. The shift from ambitious, unproven proposals to more grounded, technically supported projects is a notable trend.

Trend Analysis: From Ambition to Pragmatism

India's semiconductor strategy has evolved from initial broad calls for advanced fabs to a more pragmatic, phased approach. The early proposals, while ambitious, often lacked the critical ingredient of a proven technology partner or sufficient financial backing.

• Phase 1 (2021-2022): Initial surge of interest, including proposals for advanced nodes (e.g., 28nm) from new entrants or partnerships lacking direct fab experience. High expectations for rapid establishment.
• Phase 2 (2023): Reality check, with withdrawal of major JVs (Vedanta-Foxconn) and delays in others. Focus shifted to rigorous due diligence and the need for established players.
• Phase 3 (2024 onwards): Approval of projects with credible technology partners (Tata-PSMC) and a focus on mature, yet critical, process nodes. Emphasis on building an ecosystem from design to packaging.

This evolution suggests a learning curve in policy implementation, recognizing the immense capital and technological barriers to entry in semiconductor manufacturing. The current approach prioritizes achievable targets and proven collaborations. This pragmatic shift aligns with broader industrial policy trends, as seen in discussions around Indian Agriculture: Reforms, MSP, and Farmer Income Dynamics, where policy adjustments are made based on ground realities.
