Abstract

Disclosed is a method for growing a nitride-based semiconductor with high quality, the method including: forming a first mask layer on a substrate and forming a second mask layer on the first mask layer; performing dry etching on the first mask layer and the second mask layer to form an opening in which a part of the substrate is exposed; performing selective wet etching on the first mask layer in the opening to form a recess in which a part of the substrate is exposed; depositing a third mask layer in the recess; and growing a nitride-based semiconductor from the exposed part of the substrate on sides of the third mask layer and expanding the growth via the opening.
