Abstract
A semiconductor device comprising: a semiconductor substrate having a light receiving or emitting element; a condenser lens provided above the element; a first transparent film provided on the condenser lens for planarization over the condenser lens; a light-transmittable optical element provided above the first transparent film; and a second transparent film interposed between the first transparent film and the optical element; wherein the first transparent film is comprised of a fluorine compound so that the first transparent film is lower in refractive index than the condenser lens and the second transparent film is lower in water- and oil-repellent properties than the first transparent film.
