Abstract:
1. A semiconductor device, comprising: a nitride semiconductor layer; a gate electrode that is formed over the nitride semiconductor layer of an active region through a first insulating film, and extends in a first direction; a second insulating film that is formed to cover the gate electrode; a first contact hole that is spaced apart from the gate electrode on one side of the gate electrode, formed over the second insulating film, and extends in the first direction; a second contact hole that is spaced apart from the gate electrode on the other side of the gate electrode, formed over the second insulating film, and extends in the first direction; a source electrode that is formed within the first contact hole, and electrically connected to the nitride semiconductor layer; a drain electrode that is formed within the second contact hole, and electrically connected to the nitride semiconductor layer; a strain relaxation film that is formed over the second insulating film above the gate electrode; a third insulating film that is formed to cover the source electrode, the drain electrode, and the strain relaxation film; and a resin film that is formed over the third insulating film, wherein the gate electrode includes a first outermost sidewall and a second outermost sidewall which is opposite the first outermost sidewall, and the strain relaxation film is formed between the resin film and the first and second outermost sidewalls.
