Abstract: A Group III-V semiconductor device and a method of fabricating the same including an in-situ surface passivation layer. A two-stage cleaning process may be effectuated for cleaning a reactor chamber prior to growing one or more epitaxial layers and forming subsequent surface passivation layers, wherein a first cleaning process may involve a remotely generated plasma containing fluorine-based reactive species for removing SiXNY residual material accumulated in the reactor chamber and/or over any components disposed therein.
