ROHM and Tata Electronics Form Strategic Partnership in the Semiconductor Business

Contributing to Innovation Through Manufacturing Collaboration and Business Partnership in India

Mumbai/Kyoto, 22 Dec 2025: ROHM Co., Ltd., a leading Japanese semiconductor and electronics manufacturer, and Tata Electronics, a pioneering leader in India’s electronics and semiconductor manufacturing sector, announced today that they have entered into a strategic partnership for semiconductor manufacturing in India for both Indian and global markets. This partnership aims to leverage the expertise and ecosystem of both the companies in order to expand business opportunities for both ROHM and Tata Electronics, thereby further strengthening the relationship between the semiconductor industries of Japan and India.

As an initial focus, ROHM and Tata Electronics will establish a manufacturing framework for power semiconductors in India by combining ROHM’s leading device technologies with Tata Electronics’ semiconductor assembly and test capabilities. In addition, by leveraging the sales channels and networks of both companies, the partnership will create new business opportunities in the Indian market and deliver higher-value solutions to a wide range of customers.

As the first step in this collaboration, Tata Electronics will assemble and test ROHM’s India-designed automotive-grade Nch 100V, 300A Si MOSFET in a TOLL package, targeting mass production shipments by next year. The companies will also explore co-development of high-value packaging technologies in the future. Both companies will combine efforts to market the products manufactured through this collaboration.

The partnership embodies Government of India’s “Make in India” vision, as well as the philosophy of “Designed in India, Manufactured in India.” The ROHM–Tata Electronics partnership marks an important step toward delivering value to customers in the Indian market by building an ecosystem that includes design, development, and manufacturing – all within India. The partnership enhances Domestic Value Addition and enables stable supply of products optimized for the Indian market.

Dr Kazuhide Ino, Member of the Board, Managing Executive Officer, ROHM Co., Ltd., said, “We are delighted to collaborate with Tata Electronics, a leading Indian corporate group offering semiconductor manufacturing, assembly and test capabilities. Through this partnership, we aim to expand our lineup of packaged products manufactured in India and help build a sustainable, region-based supply chain network. We are confident that this collaboration will enable us to meet the growing demand from Indian customers seeking domestically produced semiconductors. We also envision supplying jointly manufactured products to the global market.”

Discussing the partnership, Dr Randhir Thakur, CEO & MD, Tata Electronics, said, “Tata Electronics is deeply committed to pioneering a thriving semiconductor industry in India. We are excited to partner with ROHM, a global leader in semiconductor solutions. With a strong legacy of quality and reliability across products for a broad range of markets, ROHM brings deep domain expertise to this partnership. Through our semiconductor assembly and test facilities, Tata Electronics will deliver chip packaging services to support ROHM in creating products tailored for Indian and global markets. This partnership will go a long way in bringing in trust and resilience in the global semiconductor supply chain while also expanding our respective business opportunities”.

Tata Electronics is developing offerings across the entire semiconductor manufacturing value chain to serve global customers. The company is building India’s first commercial Fab in Dholera, Gujarat, with a total investment of US$11bn, and India’s first indigenous Outsourced Semiconductor Assembly and Test (OSAT) facility in Jagiroad, Assam, with an investment of US$3bn. Collectively, the plants will serve customers across sectors like automotive, mobile devices, Internet of Things (IoT), artificial intelligence, defense, aerospace, and other key domains.
