ROHM Co., Ltd., a leading Japanese semiconductor and electronics manufacturer, and Tata Electronics have entered into a strategic partnership for semiconductor manufacturing in India for both Indian and global markets. The partnership was announced on December 22, 2025, and aims to leverage the expertise and ecosystems of both companies to expand business opportunities and strengthen the relationship between Japan's and India's semiconductor industries.

Manufacturing Framework and Initial Products

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. The partnership will create new business opportunities in the Indian market and deliver higher-value solutions to customers by leveraging the sales channels and networks of both companies.

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.

Alignment with Government Initiatives

The partnership embodies the Government of India's "Make in India" vision and 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.

Leadership Perspectives

Dr Kazuhide Ino, Member of the Board, Managing Executive Officer at ROHM Co., Ltd., expressed the company's commitment to the partnership: "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." Dr Randhir Thakur, CEO & MD of Tata Electronics, highlighted the strategic importance of the collaboration: "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."
