  • Patent number: 7595540
    Abstract: A semiconductor device including a package (2) having a plurality of wall portions (9a) and a plurality of conductor portions (4), a semiconductor element such as a solid-state image pickup device (1) mounted in an internal space of the base, thin metal wires (5) electrically connecting the semiconductor element and the conductor portions (4) between the wall portions (9a), a resin sealing material (7) implanted in the spaces between the wall portions (9a), and a closing member such as a cover glass (6). The region for connecting the thin metal wires (5) and the wall portion (9a) region overlap each other, so that the device can be reduced in size and in height. The cover glass (6) can not move easily from the correct position because the wall portions (9a) serve as supporting columns, thereby improving the yield.

  • Publication number: 20090085139
    Abstract: A solid-state image sensing element includes an effective pixel section in a central area of a light receiving surface thereof, and a ridge-shaped protruding portion is provided around the effective pixel section. A liquid transparent adhesive is applied on the effective pixel section, and a light transparent substrate is placed thereon. The light transparent substrate is in contact with the protruding portion, and is therefore prevented from sliding with the liquid adhesive serving as a lubricant. Thus, the light transparent substrate can be fixed at a predetermined position.

  • Patent number: 7294907
    Abstract: A solid-state imaging device includes a housing having a resin-molded base and ribs; metal lead pieces embedded in the housing, the metal lead pieces each having an inner terminal portion facing an inner space of the housing, an outer terminal portion exposed at a bottom surface of the housing, and a lateral electrode portion exposed at an outer lateral surface of the housing; an imaging element fixed on the base in the inner space; connecting members connecting electrodes of the imaging element respectively to the inner terminal portions; and a transparent plate fixed to an upper surface of the ribs. The die pad having a through hole is embedded in a center portion of the base so that the die pad's upper and lower surfaces are exposed, and the imaging element is fixed on the die pad. A ventilation hole to the inner space of the housing that is formed in one piece with a resin can be formed easily with a simple configuration.
