Semiconductor Manufacturing International Corporation (SMIC), the state-backed Mainland Chinese semiconductor foundry, announced that it commenced mass-production of 14 nm FinFET SoCs for Huawei's HiSilicon subsidiary, a mere one month since Huawei shifting chip orders from TSMC to it.

The company is manufacturing Kirin 710A is a revision of the original Kirin 710 SoC from 2018, built on SMIC's 14 nm node.

The 4G-era SoC is capable of powering mid-range smartphones for Huawei's Honor brand, and uses an Arm big.LITTLE setup of Cortex A53 and Cortex A57 cores.

This represents a major milestone not just for SMIC, but also Huawei, which has seen the company's isolation from cutting-edge overseas fabs such as TSMC.

Much of Huawei's fate is riding on the success of SMIC's next-generation N+1 node, which purportedly offers a 57 percent energy-efficiency gain over 14 nm FinFET, rivaling sub-10 nm nodes such as 7 nm; enabling Huawei to build 5G-era SoCs.
