Abstract:
1. A transistor device, the transistor device comprising a substrate; a fin extending along a horizontal direction on the substrate; a first source/drain region of a first type of conductivity in the fin; a second source/drain region of a second type of conductivity in the fin, wherein the first type of conductivity differs from the second type of conductivity; a channel region in the fin between the first source/drain region and the second source/drain region; a gate insulator on the channel region, wherein the gate insulator is deposited on at least two vertical side surfaces and a horizontal top surface of the channel region; a gate structure on the gate insulator, wherein the gate structure comprises at least two separately deposited portions, wherein the at least two separately deposited portions of the gate structure at least partially overlap on one of the surfaces of the channel region in a post-fabrication state of the transistor device; and wherein, in the horizontal direction, the channel region extends between the first source/drain region and the second source/drain region.
