Abstract

A semiconductor device includes a substrate, a channel layer over the substrate, an active layer over the channel layer, and a barrier structure between the substrate and the channel layer. The active layer is configured to cause a two dimensional electron gas (2DEG) to be formed in the channel layer along an interface between the channel layer and the active layer. The barrier structure is configured to block diffusion of at least one of a material of the substrate or a dopant toward the channel layer.
