Abstract
A method of manufacturing a semiconductor device includes: forming a ridge on a semiconductor layer stacked on a substrate by removing a part of the semiconductor layer; forming an electrode on the ridge so as to have a flat portion having a flat surface substantially parallel to the upper surface of the ridge and sloped portions on both sides of the flat portion with each of the sloped portions having a sloped surface that is sloped with respect to the upper surface of the ridge; forming a protective film disposed on each side of the ridge to cover a region from the side surface of the ridge to the sloped surface of the sloped portion of the electrode; and forming a pad electrode at least on an upper surface of the electrode and the protective film.
