Gate-all-around FETs having uniform threshold voltage |
| abstract |
A technique relates to a semiconductor device. An N-type field effect transistor (NFET) and a P-type field effect transistor (PFET) each include an inner work function metal, an outer work function metal, a first nanosheet including an inner channel surface having a first threshold voltage, and a second nanosheet including an outer channel surface having a second threshold voltage. The outer work function metal is modified so as to cause the outer channel surface for the second nanosheet to have the second threshold voltage within a predefined amount of the first threshold voltage for the inner channel surface of the first nanosheet, the predefined amount being within about 20 millivolts (mV). |
