ROHM Japan and Tata Electronics Form Strategic Partnership for the Semiconductor Hub in Dholera
Table of Contents
ROHM Japan contributes advanced semiconductor design expertise, power and automotive chip technology, and global quality standards while supporting product co-development. Tata Electronics provides the manufacturing backbone, including assembly, packaging, testing, and large-scale facility development in India. Together, they combine global technology leadership with domestic manufacturing capabilities to strengthen India's semiconductor manufacturing under the India Semiconductor Mission and support the growth of Dholera Smart City as a key semiconductor hub.
Major Strategic Partnership Announcement
ROHM Co., Ltd. (Japan) and Tata Electronics (India) have announced a strategic partnership to collaborate on semiconductor manufacturing in India. The agreement was officially announced on 22 December 2025, reinforcing the role of Tata Electronics semiconductor initiatives within the national semiconductor roadmap.
The partnership combines ROHM Semiconductor India's technology expertise with Tata Electronics’ assembly and test capabilities to build a strong power semiconductor manufacturing framework in India, supporting the growth of the Indian semiconductor industry.
The initial focus is on assembling and testing India-designed automotive-grade Si MOSFETs (100V, 300A) using TOLL packaging, with mass production targeted by 2026. This step contributes directly to expanding India's chip manufacturing capabilities for automotive and industrial applications.
Both companies will also explore co-development of high-value packaging technologies and leverage their sales and distribution networks to support India's semiconductor manufacturing for domestic and global markets.
Key leadership statements:
ROHM highlighted plans to expand its product lineup manufactured in India while building a region-based supply chain aligned with the India Semiconductor Mission.
Tata Electronics emphasised strengthening the Indian semiconductor industry by improving supply chain resilience and advancing local manufacturing capabilities.
How It Fits With Tata’s Broader Semiconductor Vision
This ROHM–Tata Electronics tie-up is part of a larger strategy where Tata is building an end-to-end semiconductor ecosystem in India, spanning design, fabrication, and backend manufacturing.
a. Dholera Semiconductor Fab (Front-End)
Tata Electronics, in partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corporation (PSMC), is developing a state-of-the-art semiconductor fabrication facility in Dholera Smart City, Gujarat, with an investment of around US$11 billion (~₹91,000 crore).
The fab is expected to support multiple applications, including automotive, computing, and AI chips, and play a key role in positioning the Dholera Smart City project as a national hub for semiconductor manufacturing in India. The project is also expected to generate significant employment and industrial activity.
First production from the Dholera facility is anticipated around late 2026, further strengthening India's semiconductor manufacturing capacity.
b. Backend OSAT (Assembly & Test)
Tata Electronics is also expanding its semiconductor assembly, packaging, and testing (OSAT) operations, including facilities in Assam and existing plants in Karnataka.
The ROHM partnership builds directly on Tata’s OSAT strengths, adding new scope for power semiconductor manufacturing and supporting the broader Indian semiconductor industry.
Strategic and Global Implications
- India’s semiconductor ambitions
This collaboration reflects India’s “Make in India, Designed in India” approach under the India Semiconductor Mission, helping reduce import dependence while strengthening domestic production capabilities.
It also supports supply chain diversification at a global level as demand for advanced chips continues to grow.
- Global market access
Semiconductor products developed under this partnership are intended for both Indian and international markets, enhancing India’s role in global chip manufacturing value chains.
- Complementary ecosystem growth
Tata Electronics continues to form strategic partnerships across equipment, design, and fabrication, further strengthening the semiconductor ecosystem centred around Dholera Smart City and connected industrial regions.
Dholera: Emerging Semiconductor Hub
The Dholera Special Investment Region (SIR), supported by modern infrastructure and strategic connectivity via the DMIC corridor, Ahmedabad-Dholera Expressway, and the upcoming Dholera International Airport, is emerging as a preferred destination for advanced manufacturing.
Developments such as the ABCD Building in Dholera and planned industrial zones further enhance the region’s readiness, positioning Dholera as a key node in India's semiconductor manufacturing growth.
