Huawei and SMIC quietly rolled out a new Kirin 9000C processor.
Chinese foundry SMIC may have broken the 5nm process barrier, as evidenced by a new Huawei laptop listed with an advanced chip with 5nm manufacturing tech — a feat previously thought impossible due to U.S sanctions.
Lithography resolution varies - EUV is 13.5nm light and DUV is 190 - but you can get smaller features than that.
