Huawei Technologies Co. and China’s top chipmaker have built an advanced 7-nanometer processor to power its latest smartphone, a sign Beijing is making early progress in a nationwide push to circumvent US efforts to contain its ascent. Huawei’s Mate 60 Pro is powered by a new Kirin 9000s chip that was fabricated in China by Semiconductor Manufacturing International Corp., according to a teardown of the handset that TechInsights conducted for Bloomberg News. The processor is the first to utilize SMIC’s most advanced 7nm technology and suggests the Chinese government is making some headway in attempts to build a domestic chip ecosystem, according to the research firm. Much remains unknown about SMIC and Huawei’s progress, including whether they can make chips in volume or at reasonable cost. But the Mate 60 silicon raises questions about the efficacy of a US-led global campaign to prevent China’s access to cutting-edge technology, driven by fears it could be used to boost Chinese military capabilities. With its export controls last year, the US administration tried to draw a line at preventing China from getting access to 14nm chips, or about eight years behind the most advanced technology. The US had also blacklisted both Huawei and SMIC. Now China has demonstrated it can produce at least limited quantities of chips five years behind the cutting-edge, inching closer to its objective of self-sufficiency in the critical area of semiconductors. “It’s a pretty important statement for China,” TechInsights Vice Chair Dan Hutcheson said. “SMIC’s technology advances are on an accelerated trajectory, and appear to have addressed yield-impacting issues in their 7nm technology.”
