ROHM Co., Ltd. and Tata Electronics have entered into a strategic partnership to establish semiconductor manufacturing capabilities in India, targeting both domestic demand and global markets. The collaboration brings together ROHM’s expertise in power semiconductor device technology and Tata Electronics’ expanding capabilities in semiconductor assembly, testing, and advanced packaging, reflecting a broader push to localize semiconductor production and strengthen supply chain resilience.
The partnership is designed to expand business opportunities for both companies while reinforcing cooperation between the Japanese and Indian semiconductor ecosystems. As part of the initial phase, the two companies will establish a manufacturing framework for power semiconductors in India. ROHM will contribute its device design and power semiconductor technology, while Tata Electronics will provide backend manufacturing support through its semiconductor assembly and test operations.
According to the companies, the collaboration also includes the integration of sales and distribution networks to address demand in the Indian market more effectively. This combined go-to-market approach is expected to support a wider range of customers across automotive, industrial, and power electronics applications, where demand for locally manufactured and reliable power devices is increasing.
The first product under the partnership will be an automotive-grade N-channel silicon MOSFET rated at 100V and 300A, designed in India by ROHM. Tata Electronics will assemble and test the device in a TOLL (TO-Leaded Large) package, a format commonly used in high-power automotive and industrial applications. Mass production shipments are targeted to begin next year. The companies also plan to evaluate opportunities for co-developing advanced packaging technologies, which are increasingly seen as a key differentiator in power semiconductor performance and thermal management.
The partnership aligns with the Government of India’s “Make in India” initiative and the broader objective of building end-to-end semiconductor capabilities within the country. By localizing design, assembly, and testing, the collaboration aims to increase domestic value addition and reduce dependence on overseas manufacturing. The companies said the approach is intended to ensure a more stable supply of semiconductors optimized for Indian market requirements, while also supporting exports to global customers.
Dr. Randhir Thakur, Chief Executive Officer and Managing Director of Tata Electronics, said the partnership supports the company’s objective of developing a robust semiconductor manufacturing ecosystem in India. He noted that ROHM’s experience in delivering high-quality semiconductor solutions across global markets complements Tata Electronics’ focus on advanced packaging and manufacturing services. Thakur added that the collaboration could contribute to building trust and resilience in global semiconductor supply chains.
From ROHM’s perspective, the partnership represents an opportunity to expand its portfolio of packaged semiconductor products manufactured in India. Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM, said the collaboration would support the creation of a region-based supply chain while addressing growing demand from Indian customers for domestically produced semiconductors. He also indicated that jointly manufactured products could be supplied to international markets.
