O’Melveny Advises Inpria on its Acquisition by JSR Corporation

September 17, 2021
FOR IMMEDIATE RELEASE

SILICON VALLEY—September 17, 2021—An O’Melveny corporate team advised longtime client Inpria Corporation, a pioneer in high-resolution photoresists, on 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, counsel Tim Hagen, and associate Keith Guo.

JSR issued the following press release:

JSR AGREES TO ACQUIRE EUV PIONEER INPRIA CORPORATION

September 17, 2021 07:00 AM Eastern Daylight Time

TOKYO--(BUSINESS WIRE)--JSR announced today that it has signed an agreement for the acquisition of Corvallis, OR based Inpria Corporation, 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.

In 2017 and 2020, JSR participated in Inpria’s funding rounds which resulted in JSR owning 21 percent of the company’s outstanding shares. Through this deal, JSR will acquire the remaining shares and Inpria will become a wholly owned subsidiary of JSR Corporation. 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.

“Inpria has a truly revolutionary approach to EUV lithography,” said Eric Johnson, CEO of JSR Corporation. “Not only is their technology a great fit for us, but they also, like JSR, have a culture that is centered on R&D and moves with an innovation-driven mindset. Together, we will focus our shared passion in these areas to drive our industry forward.”

Inpria has been developing its non-chemically amplified metal oxide EUV resists since the company was established in 2007 and has achieved the world's highest resolution using EUV exposure systems.

“Our team is thrilled to become part of the JSR family,” said Andrew Grenville, CEO of Inpria Corporation. “Together, we will combine Inpria’s metal oxide photoresist technology with JSR’s unmatched experience in quality, manufacturing, and customer focus to accelerate the full adoption of our platform in high volume semiconductor manufacturing. JSR’s global operations will also allow us to meet customer needs as we ramp our product introductions in critical markets. With JSR, we are committed to fulfilling the customer demands in the High-NA EUV era.”

Inpria’s metal oxide photoresist platform enables customers to pattern advanced node device architectures meeting the low defectivity levels required for manufacturing. Inpria material solutions provide the performance to significantly reduce the cost of EUV patterning for the rapidly growing fleet of EUV scanners in the field.

JSR, which has been in operation for more than 60 years manufacturing a wide range of functional materials, recently pivoted to focus its business and future expansion on its digital solutions, which includes semiconductor materials, and life sciences businesses, both of which are targeted to drive growth and are ideally suited to leverage the company’s strengths in technological innovation. JSR plans to leverage decades of experience in high volume manufacturing, quality control, supplier management, and customer engagement to further strengthen its ability to support and enable the IC industry.

The acquisition will bring a key enhancement to JSR’s already robust product portfolio of leading-edge material solutions, which enables its semiconductor manufacturing customers and partners to continue to scale efficiently and reduce cost. JSR plans to add Inpria’s non-chemically amplified metal-based resist to its photoresist product portfolio to seamlessly provide value as an advanced electronic materials supplier.
