China pushes for 70% homegrown silicon wafer use as domestic firm ramps up 12-inch production amid AI boom and export restrictions, seeking to localize critical chip supply chain

China is pushing chipmakers to source 70% of their silicon wafers from domestic suppliers, according to a report.

The implied focus is on locally made 12-inch wafers, with Xi'an Eswin expanding output to meet demand.

The move is meant to support advanced chip and AI chip production while reducing reliance on foreign suppliers.

If implemented, it could reshape wafer supply chains and help China blunt the impact of US export controls.
