PROBLEM TO BE SOLVED: To provide a semiconductor device with a structure that allows manufacturing a semiconductor photo-relay by a simple process, and to provide a method of manufacturing the same.SOLUTION: A semiconductor device includes: a semiconductor substrate; a light-emitting element provided on the semiconductor substrate; a light-receiving element being spaced apart from the light-emitting element and provided on the same surface of the semiconductor substrate as the surface on which the light-emitting element is formed; and a switching element provided on the same surface of the semiconductor substrate as the surface on which the light-emitting element is provided, so as to be electrically isolated from the light-emitting element. A method of manufacturing the semiconductor device includes the steps of: forming the light-emitting element and the switching element on the same surface of the semiconductor substrate and forming the light-receiving element so as to be electrically isolated from the light-emitting element; and etching the light-emitting element and the switching element so as to be spaced apart from each other. |
