A Chinese chemical supplier for the microelectronics industry has said it has bought a used lithography system from South Korea as part of a project to speed up development of high-end photoresist materials for advanced semiconductor production amid an ongoing national drive for self-sufficiency in the sector.
Suzhou Crystal Clear Chemical, based in an industrial estate on the outskirts of Shanghai, said in a stock filing on Tuesday that it paid US$11.02 million to buy the Dutch-made machine from South Korea’s SK Hynix, the world’s second-largest memory chip maker.
In a separate filing, the company said it would raise 550 million yuan (US$80.7 million) in convertible bonds to fund a photoresist material project aimed at reducing China’s reliance on foreign supplies amid a “complicated geopolitical environment”.
The Shenzhen-listed company, which counts Semiconductor Manufacturing International Corporation (SMIC), ChangXin Memory Technologies and Hua Hong Semiconductor as its local customers, produces ultra-pure materials used in the microelectronics industry.
“The purchase could help in developing high-end photoresist materials,” Suzhou Crystal Clear Chemical said in the filing, adding that it was important for China to be self-reliant in the critical semiconductor materials currently monopolised by firms from the US, Japan and Europe.
Photoresist is a light-sensitive material used in conjunction with laser-based lithography systems to etch circuit patterns on silicon wafers.
China currently produces only 5 per cent of the photoresists it uses in KrF ultraviolet lasers for 8-inch silicon wafers, and relies entirely on imports for more advanced ArF photoresists for 12-inch wafer production, according to the company.
Suzhou Crystal Clear Chemical did not reveal details of the lithography machine it bought from Korea, other than it was originally manufactured by Dutch company ASML, the global leader in lithography. New ASML machines for ArF lithography cost more than US$50 million.
The news comes a time when China is reinvigorating efforts to develop a self-sufficient semiconductor industry after a protracted trade war morphed into a full blown tech war, with Chinese tech companies facing increasing scrutiny and restrictions from the US government.
In the latest example, Shanghai-based SMIC is facing restrictions on its access to US technology over US concerns that its products could be diverted to the Chinese military.
