PLUG AND RECESS PROCESS FOR DUAL METAL GATE ON STACKED NANORIBBON DEVICES

Abstract:

Embodiments disclosed herein include semiconductor devices and methods of making such devices. In an embodiment, the semiconductor device comprises a plurality of stacked semiconductor channels comprising first semiconductor channels and second semiconductor channels over the first semiconductor channels. In an embodiment a spacing is between the first semiconductor channels and the second semiconductor channels. The semiconductor device further comprises a gate dielectric surrounding individual ones of the semiconductor channels of the plurality of stacked semiconductor channels. In an embodiment, a first workfunction metal surrounds the first semiconductor channels, and a second workfunction metal surrounds the second semiconductor channels.
