CFET Explained: What Stacking nFET on pFET Really Costs
Put the nFET directly on top of the pFET and the two no longer need separate floor space. On paper that halves a logic cell. An Intel engineer told IEEE Spectrum in 2023 that an inverter at maximum scaling would be 50 percent of the size of an ordinary CMOS one. Complementary FET, or CFET, is now the expected successor to nanosheets, and imec places its first use at the A7 node. The published cell heights tell a more modest story than that 50 …
