Patent ID: 7852900

Claim:
A semiconductor device comprising: a package provided with a mounting face for a semiconductor element; a frame body of the package formed so that the package opens one face among four peripheral faces bordering the mounting face and an upper face opposing the mounting face; a plurality of lead terminals fixed to the frame body; a semiconductor element electrically connected to the lead terminals and mounted on the mounting face; a cap connected so as to border a face of the frame body in a laser light output direction which is to form a periphery of an aperture portion formed on the upper face of the frame body opposing the mounting face and one face among the four peripheral faces bordering the mounting face, and which seals the semiconductor element inside the package; and a transparent member placed in a penetrating hole provided on a face of the cap in the laser light output direction and through which laser light can be outputted, wherein the semiconductor element is mounted so that a laser light output position of the semiconductor element is proximal to the transparent member.
