Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a fin disposed in a first region of the semiconductor device, the fin having first type epitaxial layers and second type epitaxial layers alternatingly disposed in a vertical direction, the first type epitaxial layers having a first material composition and the second type epitaxial layers having a second material composition different from the first material composition;
a plurality of channel members disposed in a second region of the semiconductor device and stacked in the vertical direction, the channel members having the first material composition;
first and second metal gates disposed on a top surface of the fin;
a third metal gate wrapping around each of the channel members;
a first implant region in the fin, wherein the first implant region has a first conductivity type; and
a second implant region in the fin, wherein the second implant region has a second conductivity type opposite the first conductivity type.
