Abstract:
1. A nanowire field effect transistor (FET) device including: a channel region including a silicon nanowire portion having a first distal end extending from the channel region and a second distal end extending from the channel region, the silicon nanowire portion is surrounded by a gate stack disposed circumferentially around the silicon nanowire portion; a source region including the first distal end of the silicon nanowire portion; a drain region including the second distal end of the silicon nanowire portion; a spacer adjacent to sidewalls of the gate stack and around portions of nanowire extending from the gate stack, wherein the spacer surrounds portions of nanowire extending from the gate stack; a metallic layer disposed between the source region and the spacer, between the drain region and the spacer, and surrounding portions of the nanowire not covered by the spacer or the gate stack; a first conductive member contacting a portion of the metallic layer disposed on the source region; and a second conductive member contacting a portion of the metallic layer disposed on the drain region.
