The Huawei smartphone’s microprocessor demonstrates China's advancement and has become a point of US-China tensions.
The phone symbolizes China's pursuit of a self-sufficient chip industry and challenges US efforts to limit China’s access to technology.
US officials are concerned about the transfer of advanced chip technology to Chinese military uses.
US Commerce Secretary Gina Raimondo’s Beijing trip (1m14s)
Gina Raimondo’s trip to China aimed to ease tensions over issues including technology trade.
The US has tried to prevent China from acquiring advanced semiconductors, citing national security and economic restrictions.
Raimondo's visit was eclipsed by the release of the Huawei Mate 60, which sold out quickly, signaling China's defiance against US technological restrictions.
Huawei’s Mate 60 is powered by a chip designed by Huawei and manufactured by China's largest chipmaker, SMIC.
The chip uses seven-nanometer technology, which is closer to the current state-of-the-art than the US expected, suggesting China is only a few years behind.
US sanctions previously cut off Huawei's access to TSMC’s manufacturing, driving China to seek alternatives.
Huawei and SMIC found ways to circumvent the lack of advanced Western chipmaking technology.
SMIC utilized older DUV (deep ultraviolet) lithography machines from ASML, instead of the more advanced EUV (extreme ultraviolet) machines forbidden by export controls, to push beyond expected technological limits.
Questions remain on how SMIC managed to produce advanced components with these limitations.
