CG Semi Private Limited, a subsidiary of cg power & industrial solutions , commenced commercial production at its G1 Outsourced Semiconductor Assembly and Test (OSAT) facility in Sanand, Gujarat on July 4, 2026. This milestone marks the operationalization of one of India's first dedicated OSAT facilities, established as a joint venture between CG Power, Renesas Electronics Corporation, and Stars Microelectronics. The commencement of production positions the entity to serve global customers in the automotive, defence, infrastructure, industrial, and IoT sectors.
The G1 facility, inaugurated in August 2025, features a peak capacity of up to 300 million units per year. Operations have progressed through equipment installation, process stabilization, workforce training, and customer qualification phases. The facility is equipped with high-yield production systems, robust process controls, and in-house reliability and failure analysis capabilities to ensure quality standards.
CG Semi is investing over ₹7,600 crore over five years to develop two OSAT facilities, comprising the now-operational G1 and the under-development G2. The G2 facility is expected to significantly scale production capacity upon completion. The project is backed by central and state government support and involves collaboration between the joint venture partners.
The company has focused on building a talent foundation by bringing together semiconductor professionals with experience in assembly, packaging, and testing. Investments have been made in training Indian engineers, operators, and technicians for high-volume OSAT operations. Vellayan Subbiah, Chairman of CG Power, highlighted the significance of the development, noting that the first shipment reflects the belief in the sector and the team's combined effort.
