Abstract
A nitride-based semiconductor device includes a substrate, a first step portion formed on a main surface side of a first side end surface of the substrate, a second step portion formed on the main surface side of a second side end surface substantially parallel to the first side end surface on an opposite side of the first side end surface and a nitride-based semiconductor layer whose first side surface is a (000-1) plane starting from a first side wall of the first step portion and a second side surface starting from a second side wall of the second step portion on the main surface.
