Tata Electronics Advances Semiconductor Materials Supply in India

India Semiconductor Materials Supply Collaboration

Tata Electronics and Japan-based Sumitomo Chemical have signed a Memorandum of Understanding to explore collaboration on semiconductor material supply and local manufacturing in India. The proposed cooperation is intended to strengthen the domestic semiconductor supply chain while supporting Tata Electronics' planned semiconductor fabrication facility in Dholera, Gujarat. The agreement covers potential supply of materials used in semiconductor manufacturing as well as opportunities to produce selected materials locally. The collaboration therefore addresses an important part of the manufacturing ecosystem surrounding the planned fab, extending beyond chip fabrication itself to include chemicals and other specialized semiconductor materials.

Semiconductor Materials Under Consideration

Under the MoU, Sumitomo Chemical will explore supplying semiconductor materials to Tata Electronics' upcoming fab, including photoresists, functional chemicals and high-purity chemicals. The high-purity chemical category includes hydrogen peroxide, isopropyl alcohol, ammonia water and sulfuric acid. These materials are associated with semiconductor manufacturing processes and would form part of the material supply structure required by the planned facility. The companies will also examine opportunities to manufacture Sumitomo Chemical's semiconductor materials and high-purity chemicals in India. Tata Electronics will support the Japanese company in evaluating potential local manufacturing opportunities, creating a framework for both supply and possible domestic production.

Tata Electronics Dholera Fab Investment

Tata Electronics is building India's first commercial 12-inch (300mm) semiconductor fab in Dholera, Gujarat, with a planned investment of US$11 billion. The facility is planned to manufacture chips for automotive, mobile-device and artificial-intelligence applications, with products intended to serve customers globally. The planned fab represents the manufacturing base around which the materials collaboration is being developed. By exploring domestic sourcing and production of semiconductor materials, the companies are addressing supply requirements associated with the facility while also examining whether parts of the materials ecosystem can be established within India alongside the chip manufacturing operation.

Technology Partnerships Support the Fab

Tata Electronics has also established strategic partnerships with global customers and ecosystem companies as it develops its semiconductor manufacturing capabilities. Its partnership with Taiwan-based Powerchip Semiconductor Manufacturing Corporation (PSMC) is intended to provide access to semiconductor technologies spanning 28nm to 110nm process nodes. The cooperation with Sumitomo Chemical addresses a different part of the overall ecosystem by focusing on materials rather than process technology alone. Together, these relationships illustrate how the planned facility involves multiple layers of the semiconductor manufacturing chain, including materials, equipment, process capabilities and design technologies needed to support production.

Semiconductor Manufacturing Ecosystem in India

The Tata Electronics-Sumitomo Chemical collaboration is expected to cover the materials side of the semiconductor manufacturing ecosystem alongside equipment, process and design technologies. Tata Electronics said the cooperation will support development of a domestic semiconductor manufacturing base in India. Sumitomo Chemical supplies semiconductor and display materials through its ICT & Mobility Solutions business and has supplied materials used in semiconductor manufacturing processes to customers globally. The proposed local manufacturing evaluation could therefore complement the planned fab by examining domestic availability of specialized materials. The scope remains subject to further evaluation under the MoU, so the agreement itself represents an exploration of supply and manufacturing opportunities rather than a confirmed production commitment for every material category.

Industry Impact & Outlook

The collaboration could strengthen the supporting supply network around India's planned semiconductor manufacturing capacity by addressing both material sourcing and potential local production. For Tata Electronics, access to semiconductor materials is directly relevant to the development of its Dholera fab, while Sumitomo Chemical gains an opportunity to evaluate manufacturing possibilities closer to an emerging semiconductor production base. The broader significance lies in developing multiple layers of the domestic ecosystem rather than focusing solely on fabrication capacity. Further evaluations will determine which materials can be manufactured locally and how the companies structure future supply arrangements, making the next stage of the collaboration important for translating the MoU into specific manufacturing or sourcing activities.
