THIN FILM TRANSISTORS HAVING STRAIN-INDUCING STRUCTURES INTEGRATED WITH 2D CHANNEL MATERIALS

Abrégé

Thin film transistors having strain-inducing structures integrated with two-dimensional (2D) channel materials are described. In an example, an integrated circuit structure includes a two-dimensional (2D) material layer above a substrate. A gate stack is on the 2D material layer, the gate stack having a first side opposite a second side. A first gate spacer is on the 2D material layer and adjacent to the first side of the gate stack. A second gate spacer is on the 2D material layer and adjacent to the second side of the gate stack. The first gate spacer and the second gate spacer induce a strain on the 2D material layer. A first conductive structure is on the 2D material layer and adjacent to the first gate spacer. A second conductive structure is on the 2D material layer and adjacent to the second gate spacer.
