Abstract:
1. A method for manufacturing a complementary nanowire tunnel field effect transistor semiconductor device, comprising: providing a stack comprising a layer of sacrificial material atop a layer of channel material; removing material from the layer of channel material and the layer of sacrificial material so as to form at least one first nanowire and at least one second nanowire; forming a nanowire tunnel field effect transistor of a first dopant type by removing and replacing the sacrificial material in the at least one first nanowire with heterojunction material of a first doping material of a first dopant type; and thereafter forming a nanowire tunnel field effect transistor of a second dopant type by removing replacing the sacrificial material in the at least one second nanowire with heterojunction material of a second doping material of a second dopant type, whereby a complementary nanowire tunnel field effect transistor device comprising at least one nanowire tunnel field effect transistor of the first dopant type and at least one nanowire tunnel field effect transistor of the second dopant type is obtained.
