Abstract

A method for fabricating a semiconductor device includes forming a first mask on a substrate, forming a first side wall of a fin by performing a first etching of the substrate using the first mask, forming a second mask on the substrate, the second mask being different from the first mask, and forming a second side wall of the fin by performing a second etching of the substrate using the second mask.
