Abstract
A semiconductor device includes a substrate, a first III-V compound layer, a gate electrode, drain trenches, and at least one drain electrode. The drain trenches are disposed and arranged with high integrity. The substrate has a first side and a second side opposite to the first side. The first III-V compound layer is disposed at the first side of the substrate. The gate electrode is disposed on the first III-V compound layer. Each of the drain trenches extends from the second side of the substrate toward the first side of the substrate and penetrates the substrate. The drain trenches are arranged regularly. The drain electrode is disposed in at least one of the drain trenches.
