A method for fabricating a semiconductor device including a semiconductor layer structure, a source electrode and, a drain electrode formed on the semiconductor layer structure, and a source interconnection connected to the source electrode is provided. The method includes the steps of: (a) forming the semiconductor layer structure on a substrate; (b) forming a metal layer structure so as to cover the semiconductor layer structure; (c) forming a resist layer having a predetermined pattern on the metal layer structure: (d) performing a first etching process for the metal layer structure using the resist layer as a mask so as to form the source electrode, the drain electrode and the source interconnection; and (e) performing a second etching process for the semiconductor layer structure using the resist layer as a mask so as to form a transistor gap portion between the source electrode and the drain electrode. The respective first and second etching processes in the steps (d) and (e) are performed using the same resist layer as the mask in the same chamber.
