Claim Text:
1. A method of manufacturing a semiconductor device, comprising: (a) forming an insulating film over a semiconductor substrate; and (b) simultaneously forming a source electrode, a drain electrode, and at least one field plate electrode over the insulating film, the formed source electrode and the formed drain electrode being located on opposite sides of a gate electrode, and each formed field plate electrode being located between the gate electrode and the drain electrode and having a field plate contact formed in the insulating film so as to couple the respective field plate electrode to the semiconductor substrate, wherein each of the formed source and drain electrodes has a portion of the insulating film interposed between the respective electrode and the semiconductor substrate, and wherein by the step (b), each field plate electrode is formed so as to extend from the respective field plate contact toward at least one of the source electrode and the drain electrode in a plan view.
