Quick Summary

Chinese researchers at the Chinese Academy of Sciences have made initial progress in developing 3-nanometer chips using less advanced deep ultraviolet (DUV) lithography technology, as reported by Taiwanese media Digitimes. This breakthrough comes despite US sanctions preventing China from accessing more sophisticated extreme ultraviolet (EUV) tools necessary for producing chips below the 7-nm node, indicating China's efforts to advance its semiconductor industry independently of Western technology.

Story summary

In a significant development, Chinese researchers at the state-backed Chinese Academy of Sciences (CAS) have made progress in developing 3-nm chips using less advanced deep ultraviolet (DUV) lithography technology. This breakthrough was reported by Digitimes, a Taiwanese media outlet, on Thursday and stems from a speech given by Ye Tianchun, a veteran researcher at the CAS’s Institute of Microelectronics (IMECAS). The Chinese team has established an initial development path for gate-all-around (GAA) devices without access to advanced extreme ultraviolet lithography (EUV) tools. US sanctions prevent ASML, a Dutch equipment manufacturer, from selling its EUV machines essential for producing chips below the 7-nm node to Chinese clients. Although this progress is not yet ready for mass production, it demonstrates China's ability to advance chip manufacturing despite technological and trade barriers.
