ABSTRACT:
An electronic device can include a semiconductor fin overlying an insulating layer. The electronic device can also include a semiconductor layer overlying the semiconductor fin. The semiconductor layer can have a first portion and a second portion that are spaced-apart from each other. In one aspect, the electronic device can include a conductive member that lies between and spaced-apart from the first and second portions of the semiconductor layer. The electronic device can also include a metal-semiconductor layer overlying the semiconductor layer. In another aspect, the semiconductor layer can abut the semiconductor fin and include a dopant. In a further aspect, a process of forming the electronic device can include reacting a metal-containing layer and a semiconductor layer to form a metal-semiconductor layer. In another aspect, a process can include forming a semiconductor layer, including a dopant, abutting a wall surface of a semiconductor fin.
