Abstract: A method for manufacturing a semiconductor device includes: a fixing step in which semiconductor chips are mounted on and fixed to predetermined positions on an upper surface of a single starting substrate to form individual substrates; a connection step in which electrodes of the semiconductor chips and of the starting substrate are connected by wires; a sealing step in which on the upper surface of the starting substrate, the resin is potted among the semiconductor chips to seal an entire lateral circumference of each of the semiconductor chip; a bonding step in which a single starting protective cover to form individual protective covers is bonded to a surface of the resin so as to extend the semiconductor chips; and a cutting step in which an assembly of the semiconductor devices formed by bonding the starting protective cover to the starting substrate via the resin is cut to the semiconductor devices.

Abstract: A photoreception device includes: a substrate; a photoreceptor element including a photoreceptor portion upon an upper surface thereof and a lower surface thereof is mounted upon the substrate; and an insulating resin mass that contains a flat upper surface and an opening that exposes the photoreceptor portion of the photoreceptor element, that is formed upon the substrate to be thicker than thickness of the photoreceptor element, and that adheres closely against side surfaces of the photoreceptor element, the side surfaces surrounding the photoreceptor element. The insulating resin mass contains a step portion that is provided to a height between the flat upper surface thereof and the upper surface of the photoreceptor portion; and the step portion extends parallel to at least one pair of mutually opposed side surfaces of the photoreceptor element, at a periphery of the opening.
