Mitsui, Kaynes Launch $280M OSAT Facility in India to Bolster Semiconductor Supply Chain Resilience

Mitsui & Co. and Kaynes Technology have entered a strategic partnership to develop a new outsourced semiconductor assembly and test (OSAT) facility in the southern Indian state of Tamil Nadu. The $280 million project, scheduled for completion by late 2027, will be situated within an industrial park near Chennai and is expected to initially support 300 direct jobs, with plans to expand operations based on demand. The facility will focus on advanced packaging solutions for mid-to-high-end semiconductors, including packages tailored for AI accelerators and automotive microcontrollers. This development reflects a growing trend of semiconductor supply chain realignment, with major players seeking to reduce reliance on traditional hubs in East Asia. While Taiwan Semiconductor Manufacturing (TSMC) and China’s SMIC remain dominant in front-end manufacturing, the expansion of OSAT capacity in India provides a critical step in building end-to-end processing capabilities outside of Asia’s established centers. The new plant will target key clients in the global electronics and automotive sectors, including those supplying NVIDIA (NVDA), whose demand for advanced packaging continues to surge. The project aligns with India’s Production-Linked Incentive (PLI) scheme for semiconductors, which offers financial support to domestic and foreign investors in building fabrication and post-fabrication infrastructure. The facility is expected to serve a mix of global and regional clients, with initial output focused on 2.5D and 3D IC packaging, technologies increasingly vital for high-performance computing and data center applications. Capacity is projected to reach 120,000 wafers per month by Year 3 of operation. Market participants view the initiative as a strategic move that could help mitigate geopolitical and logistical risks in semiconductor supply chains. While the immediate impact on stock prices of TSMC, SMIC, or NVDA is expected to be limited, the long-term implications for global OSAT market dynamics and regional manufacturing equilibrium are notable. The project underscores increasing international investment in India’s semiconductor ecosystem, signaling a shift toward a more geographically diversified semiconductor value chain.
