Six weeks after sanctions-hit Huawei staged a surprise comeback with a 5G smartphone based on a 7-nanometre (nm) processor manufactured by Chinese foundry Semiconductor Manufacturing International Corp (SMIC), Washington ratcheted up its China export controls to cover a slew of process gear needed for semiconductor wafer fabrication, including lithography, etching, deposition, implant and cleaning. The latest rules also came after successful US efforts since January to woo Japan and the Netherlands to join it in restricting exports of advanced semiconductor tools to China, moves aimed at curbing Beijing’s ability to leverage foreign tech for military applications.
