Huawei alone is causing big ripples among Western tech communities who assumed US export controls curbing access to chip supplies had sidelined China Inc. Huawei's 7-nanometer chip, which powers the smartphone's processor, was designed in-house and manufactured by the mainland's top chip vendor, Semiconductor Manufacturing International Corporation (SMIC). While there are questions about whether Huawei's 5G capabilities match Apple's, the 7-nanometer chip"demonstrates the technical progress China's semiconductor industry has been able to make without Extreme ultraviolet lithography (EUV) tools," says Dan Hutcheson, vice chair of TechInsights. Huawei's exhibit dominated this year's Mobile World Congress held in Barcelona.
