    摘要: According to example embodiments, a substrate structure may include a GaN-based third material layer, a GaN-based second material layer, a GaN-based first material layer, and a buffer layer on a non-GaN-based substrate. The GaN-based first material layer may be doped with a first conductive type impurity. The GaN-based second material layer may be doped with a second conductive type impurity at a density that is less than a density of the first conductive type impurity in the first GaN-based material layer. The GaN-based third material layer may be doped with a first conductive type impurity at a density that is less than the density of the first conductive type impurity of the GaN-based first material layer. After a second substrate is attached onto the substrate structure, the non-GaN-based substrate may be removed and a GaN-based vertical type semiconductor device may be fabricated on the second substrate.

    摘要: A semiconductor device including a group III-V barrier and a method of manufacturing the semiconductor device, the semiconductor device including: a substrate, insulation layers formed to be spaced apart on the substrate, a group III-V material layer for filling the space between the insulation layers and having a portion protruding higher than the insulation layers, a barrier layer for covering the side and upper surfaces of the protruding portion of the group III-V material layer and having a bandgap larger than that of the group III-V material layer, a gate insulation film for covering the surface of the barrier layer, a gate electrode formed on the gate insulation film, and source and drain electrodes formed apart from the gate electrode. The overall composition of the group III-V material layer is uniform. The barrier layer may include a group III-V material for forming a quantum well.
