en.Wedoany.com Reported - India's semiconductor industry is developing along two parallel tracks: fast and slow. On the fast track, private capital is pouring into the outsourced semiconductor assembly and test (OSAT) sector, with total announced investments reaching approximately 640 billion rupees. These include Tata Electronics' 270 billion rupee assembly and test facility in Assam, CG Semi's 76 billion rupee project, Kaynes Semicon's 33 billion rupee facility, the HCL-Foxconn joint venture in Uttar Pradesh, and Suchi Semicon's $100 million facility in Gujarat. These investments target rapidly growing domestic markets such as smartphones, automobiles, industrial equipment, and telecommunications, while also benefiting from the global trend of supply chains shifting from centralization to decentralization. A leading-edge wafer fab can cost between $10 billion and $25 billion and take years to become operational, whereas a typical OSAT facility costs between $300 million and $2 billion and has a much shorter time to production. India accounts for over one-fifth of the global chip design workforce; OSAT allows these design talents to connect with physical manufacturing bases without the capital intensity required for wafer fabrication. Suchi Semicon's facility in Gujarat targets mature packaging products currently entirely imported by India, with plans to begin operations in August, start shipments in September, and achieve mass production by May 2027. This timeline stands in stark contrast to the slow pace of India's established wafer fab.
In stark contrast to the rapid implementation of OSAT projects, the modernization of India's only state-owned wafer fab, the Semiconductor Laboratory (SCL) in Mohali, has stalled. The facility, commissioned in 1984, is still recovering from a fire accident in 1989. In December 2025, Tata Semiconductor Manufacturing, Cyient Semiconductors, and Applied Materials were selected to lead a 45 billion rupee upgrade plan, but six months later, the contract cannot be formally awarded pending approval from the Union Cabinet. The plan aims to increase the wafer start volume of SCL's outdated 180nm production line from 700 wafers per month to 1,500 wafers per month, to meet stable demand from the defense, aerospace, industrial, and medical equipment sectors. However, the project is deadlocked due to disagreements over the pricing and allocation of supporting land, and a parallel expansion plan could lead to overlapping contract scopes. The SCL upgrade likely needs financial alignment with the proposed 1.25 trillion rupee Semiconductor Mission 2.0 (expected by the end of 2026), adding further complexity.
OSAT is primarily a greenfield investment, private sector-led story, while SCL Mohali is a brownfield upgrade, public sector project, facing two major challenges: institutional memory and inter-ministerial coordination. Analysts believe that while OSAT is an effective entry point for India into the global chip supply chain, the industry's long-term sustainability ultimately depends on the country's ability to reduce its reliance on imported technology in materials, equipment, chip design IP, and wafer fabrication. In the future, advanced packaging, specialty chemicals, substrates, precision equipment manufacturing, and selective wafer fabrication are expected to become the visible next-stage targets.
