A Chinese chip-making partner is collaborating with a government-backed company to develop a low-tech solution to replace extreme ultraviolet lithography machines. These machines are used to etch circuitry patterns on silicon wafers and are crucial for placing billions of transistors inside chipsets. The current EUV machines are manufactured by Dutch firm ASML. The largest foundry in China, SMIC, used the 7nm Kirin 9000s 5G application processor for Huawei's Mate 60 series. However, SMIC needs more advanced chips as DUV machines cannot produce 5nm chipsets.
and a chip-making partner backed by the Chinese government are working on a low-tech way to replace the extreme ultraviolet lithography machines that. These machines etch extremely thin circuitry patterns on silicon wafers and help foundries place billions of transistors inside chipsets. The EUV machines are made by one manufacturer, Dutch firm ASML .
The 7nm Kirin 9000s 5G application processor built by China's SMIC, the largest foundry in the country, was used by Huawei for the Mate 60 series it shocked the world with last August. It was the first 5G chip used on a Huawei phone since 2020's Mate 40 Pro and SMIC is believed to have built the components using the deep ultraviolet lithography machines that it has been allowed to buy from ASML over the years.
Huawei's patent application, filed with the China National Intellectual Property Administration, was released on Friday and the filing said,"Adoption of this patent will increase the design freedom of circuit patterns.
The patent said that the technique can help SMIC and Huawei avoid having to get access to a EUV machine and reduce manufacturing costs. Dan Hutcheson, vice-chairman at research firm TechInsights, says that quadruple-patterning should help China make 5nm chips but in the long run it still needs to get its hands on an EUV machine.
With China currently building smartphone chipsets at 7nm, the country remains two generations behind the 3nm node that TSMC used to build the A17 Pro AP currently powering theAlan, an ardent smartphone enthusiast and a veteran writer at PhoneArena since 2009, has witnessed and chronicled the transformative years of mobile technology.
