JSR plans to acquire Inpria/the manufacturer of extreme ultraviolet (EUV) lithography metal oxide photoresist

On September 17, Japanese semiconductor material manufacturer JSR Co., Ltd. announced that it will acquire Inpria, headquartered in Corvallis, Oregon, USA. The latter is the world's leading extreme ultraviolet (EUV) lithography metal oxide photoresist design Developer and manufacturer.


JSR participated in Inpria's financing rounds in 2017 and 2020, and owns 21% of the company's outstanding shares.


Through this transaction, JSR will acquire the remaining shares of Inpria, and Inpria will become a wholly-owned subsidiary of JSR. The execution of the acquisition depends on a number of conditions, including the receipt of regulatory approvals, and is expected to be completed by the end of October 2021. The two parties have reached an agreement of US$514 million (approximately 56.54 billion yen) on the commercial value of Inpria.


Photoresist is one of the microelectronic chemicals with the highest technical threshold in the world. The R&D and production of high-end products are mainly monopolized by a few companies such as Japanese JSR, Shin-Etsu Chemical, and Tokyo Ohka.


According to data, JSR was established in 1957 and is a world-renowned semiconductor material manufacturer. Its main products include photolithography materials (photoresist, multilayer materials), CMP materials, inlay materials, cleaning agents, etc., and other businesses include synthetic resins. Manufacturing, life sciences, etc.


Inpria is headquartered in Oregon, USA. Since its establishment in 2007, Inpria has been committed to the research and development of metal EUV photoresist, achieving the world's highest EUV exposure performance and marginal resolution, which has become the highest in extreme ultraviolet lithography (EUV). A pioneer in resolution metal oxide photoresist, it is a global leader in the design, development and manufacturing of metal oxide photoresists.


JSR said that the acquisition is a strategic approach. By adding Inpria's metal resist to our photoresist products, it can seamlessly provide value as a semiconductor material supplier.
