Abstract
A semiconductor device includes a semiconductor layer stacked on a substrate, a stripe-shaped ridge formed on a surface of the semiconductor layer, and electrode formed on an upper surface of the ridge and a protective film disposed on each side of the ridge. The electrode includes 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. The protective film covers a region from a side surface of the ridge to the sloped surface of the sloped portion of the electrode.
