Recent findings by TechInsights reveal that SMIC, China's leading semiconductor manufacturer, is still operating at a 7nm process for their Kirin X90 SoC, contrary to expectations of a transition to 5nm technology. This discovery highlights the ongoing challenges posed by US trade restrictions on advanced semiconductor technology and equipment. While SMIC has announced the development of a 5nm node, it has yet to achieve production at scale. The study emphasizes the inherent difficulties of maintaining high yield rates in the face of technological limitations.
Despite SMIC allegedly developing a 5nm process, TechInsights reveals that their Kirin X90 SoC is still based on the outdated 7nm N+2 technology, limiting innovation.
The findings underscore the challenges SMIC faces in overcoming US trade policies, showing that progress in semiconductor technology is hampered by restrictions on essential lithography equipment.
