Abstract: The present invention makes it possible to improve the characteristic of a semiconductor device using a nitride semiconductor. An electrically-conductive film is formed above a gate electrode above a substrate with an interlayer insulation film interposed and a source electrode coupled to a barrier layer on one side of the gate electrode and a drain electrode coupled to the barrier layer on the other side of the gate electrode are formed by etching the electrically-conductive film. On this occasion, the source electrode is etched so as to have a shape extending beyond above the gate electrode to the side of the drain electrode and having a gap (opening) above the gate electrode. Successively, hydrogen annealing is applied to the substrate. In this way, by forming the gap at a source field plate section of the source electrode, it is possible to efficiently supply hydrogen in the region where a channel is formed in the hydrogen annealing process.
