Abstract
A method includes forming a gate dielectric layer over a gate electrode layer; forming a 2-D material layer over the gate dielectric layer; forming source/drain contacts over source/drain regions of the 2-D material layer, in which each of the source/drain contacts includes an antimonene layer and a metal layer over the antimonene layer; and after forming the source/drain contacts, removing a first portion of the 2-D material layer exposed by the source/drain contacts, while leaving a second portion of the 2-D material layer remaining over the gate dielectric layer as a channel region.
