Semiconductor device and method for forming the same
Abstract:
A semiconductor device is provided. The semiconductor device includes a substrate and a first III-V group compound semiconductor layer disposed on the substrate. The first III-V group compound semiconductor layer includes a fin structure having a top surface, a first sidewall, and a second sidewall opposite to the first sidewall. The semiconductor device also includes a second III-V group compound semiconductor layer disposed on the first III-V group compound semiconductor layer. The first III-V group compound semiconductor layer and the second III-V group compound semiconductor layer are made of different materials. The semiconductor device also includes a gate electrode disposed on the second III-V group compound semiconductor layer.
