Claim Text:
1. A device comprising a nanosheet field effect transistor (FET), the nanosheet FET comprising: a well that is doped with impurities at a surface of a substrate; a channel comprising a plurality of stacked nanosheets on the well, ones of the plurality of stacked nanosheets comprising a semiconductor material that is doped with impurities of a same conductivity type as the impurities of the well and ones of the plurality of stacked nanosheets spaced apart from each other in a direction that is perpendicular to the surface of the substrate; a gate comprising a workfunction metal on the plurality of nanosheets, between adjacent ones of the plurality of nanosheets, and between the plurality of nanosheets and the well; a conductive material adjacent the plurality of nanosheets and that electrically connects ones of the plurality of nanosheets to the well; an isolation layer on the well that electrically insulates the well from the workfunction metal.
