Offering an update on its work with complementary field-effect transistors (CFETs) as part of the company's European Technology Symposium 2023, TSMC has revealed that it has working CFETs within its labs. But even with the progress TSMC has made so far, the technology is still in its early days, generations away from mass production. In the meantime, ahead of CFETs will come gate-all-around (GAA) transistors, which TSMC will be introducing with its TSMC's upcoming N2 (2nm-class) production nodes. One of TSMC's long-term bets as the eventual successor to GAAFETs, CFETs are expected to offer advantages over GAAFETs and FinFETs when it comes to power efficiency, performance, and transistor density. However, these potential benefits are theoretical and dependent on overcoming significant technical challenges in fabrication and...
