Patent ID: 8471289

Claim:
A semiconductor device, comprising: an insulating resin layer; a wiring layer disposed on one main surface of said insulating resin layer; a bump protruding on a side of said insulating resin layer, the bump being formed integrally with said wiring layer; a semiconductor element in which an element electrode electrically connected to said bump is formed; a support member having an opening formed such that at least said semiconductor element is exposed, said support member disposed on the other main surface of said insulating resin layer; and a sealing member provided on said support member in such a manner as to block the opening, wherein a space is provided between an inner wall of the support member and a side surface of the semiconductor element, and a space in the opening in which the semiconductor element is placed is air-tightly sealed by the sealing member, wherein said semiconductor device is a laser element, and said sealing member has translucency, wherein a laser light emitted from the laser element is reflected by inner wall surface of said support member or a film provided on the inner wall surface and transmits through said sealing member.
