An opening for forming a gate electrode is provided by a first photoresist pattern formed on an insulating film. Reactive ion etching by inductively coupled plasma is applied to the insulating film through the first photoresist pattern as a mask to thereby expose the surface of a GaN semiconductor layer, evaporating thereon a gate metal such as NiAu, thereby forming the gate electrode by self-aligned process. This prevents an oxidized film from being formed on the surface of the semiconductor layer. After the gate electrode is formed, a second photoresist pattern is formed to form a field plate on the gate electrode and the insulating film through the second photoresist pattern as a mask. Thereby, Ti having a high adhesiveness with an insulating film made of SiN or the like can be used as a field plate metal.

Method for manufacturing a field effect transistor having a field plate

A semiconductor device has source and drain electrodes formed on a substrate, a gate insulation film formed on the substrate between the source and drain electrodes, and a gate electrode formed on the gate insulation film. These elements are all covered by a dielectric sub-insulation film. An opening is formed in the sub-insulation film, partially exposing the gate electrode. A field plate extends from the top of the gate electrode down one side of the gate electrode as far as the sub-insulation film covering the gate insulation film, filling the opening. The thickness of the sub-insulation film can be selected to optimize the separation between the field plate and the substrate for the purpose of reducing current collapse by reducing electric field concentration at the edge of the gate electrode.

The present invention provides a semiconductor device having a recess-structured ohmic electrode, in which the resistance is small and variation in the resistance value caused by manufacturing irregularities is small. In the semiconductor device of the present invention, a two-dimensional electron gas layer is formed on the interface between a channel-forming layer and a Schottky layer by electrons supplied from the Schottky layer. The ohmic electrode comprises a plurality of side faces in ohmic contact with the two-dimensional electron gas layer. At least a part of side faces of the ohmic electrodes are non-parallel to a channel width direction. In a preferred embodiment of the present invention, the side faces have a saw tooth form or a comb tooth form. Since the contact area between the ohmic electrode and the two-dimensional electron gas layer is increased, ohmic resistance is reduced.
