Abstract
A semiconductor element and a manufacturing method of the semiconductor element are provided. A ridge waveguide type semiconductor integrated element includes: an electrode of an EA portion and an electrode of an LD portion which are arranged so as to be away from each other; a contact layer of the EA portion and a contact layer of the LD portion which are arranged so as to be away from each other and in each of which the electrode is formed on an upper surface and an edge of at least a part of the upper surface is set to the same electric potential as that of the electrode; a passivation film as an insulative concave/convex structure extending from an edge of one of the two contact layers to an edge of the other contact layer; and a polyimide resin for embedding the passivation film.
