Abstract:
1. A method of fabricating a semiconductor device, comprising: forming a first III-V family layer over a substrate, the first III-V family layer including a surface having a first surface morphology; performing an ion implantation process to the first III-V family layer through the surface, the ion implantation process changing the first surface morphology into a second surface morphology; performing a thermal process to the first III-V family layer; and after the ion implantation process is performed, forming a second III-V family layer over the first III-V family layer, wherein the second III-V family layer has a material composition different from that of the first III-V family layer, and wherein the first III-V family layer and the second III-V family layer each include a respective element in a III family of a periodic table and a respective element in a V family of the periodic table.
