Huawei’s semiconductor making arm HiSilicon has placed 14nm chip orders to China’s Semiconductor Manufacturing International Corporation (SMIC), says a report regarding this subject.

SMIC has recently received orders for 14nm FineFET process manufacturing from HiSilicon, which has been among major clients of TSMC’s Nanjing fab that was opened in late 2018 and entered directly 16nm FinFET chip production, reported Digitimes.

This could also be a result of recent US decisions to limit US technology supplies from foreign firms including TSMC from 25% to 10%, which affects TSMC’s supplies of 14nm, as it contains over 10% US tech for the manufacturing process.

However, The 7nm chip manufactured by TSMC contains only 9 percent of the US tech, so it can still supply the 7nm products.

14nm chips are mainly used for network equipment and as announced by Huawei, the Chinese company now producing its own network equipment chips without US technologies.
