Abstract
Various methods for fabricating non-planar integrated circuit devices, such as FinFET devices, are disclosed herein. An exemplary method includes forming a rib structure extending from a substrate; forming a two-dimensional material layer (including, for example, transition metal dichalcogenide or graphene) on the rib structure and the substrate; patterning the two-dimensional material layer, such that the two-dimensional material layer is disposed on at least one surface of the rib structure; and forming a gate on the two-dimensional material layer. In some implementations, a channel region, a source region, and a drain region are defined in the two-dimensional material layer. The channel region is disposed between the source region and the drain region, where the gate is disposed over the channel region. In some implementations, the patterning includes removing the two-dimensional material layer disposed on a top surface of the substrate and/or disposed on a top surface of the rib structure.
