Chinese Non-Silicon transistor claims to beat Intel/TSMC by 40%

Bismuth-based Transistor tech achieves better performance than silicon

Chinese researchers at Peking University have utilised new materials to create 2D GAAFET transistor technology that outperforms all silicon chips. These new transistors are Bismuth-based, and claim to deliver 40% higher performance than TSMC’s N3 (3nm) lithography node with 10% greater power efficiency.

The team behind its research claims to have compared its transistors to those from Intel, TSMC, Samsung, and others, with its transistors delivering leadership performance. However, it remains to be seen how manufacturable Bismuth-based chips are. Will China’s new transistor technology become productised before Western rivals achieve similar feats?

China is heralding this transistor breakthrough as a potential game-changer for the Chinese tech sector. As Western chipmakers continue battling against the limitations of silicon lithography, China could push forward into the post-silicon era with their new chipmaking materials.

Sanctions have prevented China from accessing the world’s most advanced chipmaking tools. This has forced China to invest heavily in semiconductor research. China aims to catch up to Western chipmakers and leapfrog them with innovative new technologies. Will China succeed? Who knows. All we know is that the China/US tech war will continue.

While Peking University’s Bismuth-based transistor tech is impressive, it remains to be seen if it can become productised. Will future Chinese chips be made without silicon? Will China enter the “post-silicon” era ahead of its rivals? If China can’t capitalise on this technology, it will remain behind Western chipmakers.
