For example, Huawei has been able to scoot around TSMC’s weak end customer checks andsecure thousands of leading edge wafers through Bitmain / Sophgo, and many other established Chinese design rms. While this is a huge failure in enforcement of the export controls, it’s also relatively low volume compared to domestic fabrication of the Ascend 910B. Huawei has been relying on primarily SMIC to produce their domestic AI chip and they have run tens of thousands of wafers of the main compute chiplet on their domestic SMIC N+2 (~7nm) and N+3 (~6nm) process nodes.Sanctions violations are egregious. SMIC produces 7nm-class chips including the Kirin 9000S mobile SoC and Ascend 910B AI accelerator. Two of their fabs are connected via wafer bridge, such that an automated overhead track can move wafers between them. For production purposes, this forms a continuous cleanroom and eectively one fab.也就是说,美国的咨询机构没有二选一,而是认为美国的科技封锁和贸易管制全都失败了,哈哈哈哈。
