Inpria Corp. (Corvallis, Oregon), a developer of photoresists for extreme ultraviolet lithography, has filed a patent infringement lawsuit against Lam Research Corp.
Inpria alleges infringement of its patented metal-oxide photoresist technology for extreme ultraviolet (EUV) semiconductor processing and has filed suit in the District Court of Delaware.
Inpria references three patents and seeks an injunction against Lam’s sale of a certain dry resist technology plus damages.
“Inpria has made significant investments in the development of new materials and technologies, and we are confident that our patent rights will be upheld in this case,” said Andrew Grenville, CEO of Inpria, in a statement.
The value of damages sought or whether they should be triple damages for wilful infringement of patents was not disclosed by Inpria.
Inpria was founded in 2007 and backed for many years by multiple strategic investors from the chip industry. It is now a wholly-owned subsidiary of Japan’s JSR Corp.
