JSR Corporation’s $514 Million Acquisition of Inpria

O’Melveny & Myers advised Inpria on the deal while Pillsbury Winthrop Shaw Pittman represented JSR.

Inpria Corporation, a pioneer in high-resolution photoresists, announced its acquisition by JSR Corporation, a research-oriented, multinational company focused on the digital solutions, including semiconductor, and life sciences markets. Under the terms of the deal, JSR will acquire Inpria for USD $514 million.

Inpria is the world’s leading innovator of metal oxide photoresist design, development and manufacturing for extreme ultraviolet (EUV) lithography. EUV technology is already in use in commercial production in the most advanced lithography processes used in semiconductor manufacturing and, as the industry moves to smaller critical dimensions in chip manufacturing, its use is expected to increase substantially.

The execution of the acquisition is subject to several conditions, including the receipt of regulatory clearance, and is expected to be completed by the end of October 2021.

Guiding the deal for Inpria were managing partner of O’Melveny’s Silicon Valley office, Paul Sieben (Picture), counsel Tim Hagen, and associate Keith Guo.

The Pillsbury team is led by Corporate partners Christopher Patay and Tai Kimoto and includes Corporate associates Jeong Choi and Hana Cho.
