Chinese smicer SMIC started production of 14nm chips for Huawei

Due to US sanctions aimed at preventing Huawei’s subsidiary Hisilicon from placing orders with the Taiwanese foundry company TSMC, the company decided in mid-April to migrate its production in 14 nm to SMIC, the largest Chinese foundry. Just a month later, the Semiconductor Manufacturing International Corporation has already begun to produce them.

This is the first time that Huawei has outsourced its production to someone other than TSMC. The chip concerned is a 4G Soc, the Kirin 710A, a revision of the original 2018 Kirin 710. Logically engraved in 14 nm, it features four Cortex A-73 CPU cores and four Cortex-A53 CPU cores.

14 nm insufficient for 5G
By comparison, the first chip engraved in 14 nm by Intel dates back to 2014. In addition, according to Extremtech, the 14 nm SMIC would actually match the 22 nm Intel process “in some ways”. In any case, this is already a good proof of the progress of SMIC over the years.
TSMC finally plans to build a 5nm plant in the United States
The company, founded in 2000, recorded 45 nm in 2007 and 28 nm in 2014. However, for it to be able to produce 5G Soc for Huawei, it will need to mobilize its "N+1" process, perhaps in 7 nm, scheduled for the end of the year. This is expected to improve performance by 20% and reduce energy consumption by 57% compared to 14 nm.
