A solid image-pickup device has a semiconductor substrate, which includes an image-pickup area having a plurality of light sensors arranged thereon. A transparent plate having the same shape and the same size as those of the semiconductor substrate when viewed as a plan view is bonded to the surface of the semiconductor substrate. Also, a through hole extends from the second side of the semiconductor device towards the first side. An electrically conductive material is located in the through hole. Additionally, the electrically conductive material is physically connected to at least a portion of a lower surface of a laminar layer portion comprising at least one conductive layer located at the first side of the semiconductor substrate and is electrically connected to the laminar layer portion.

Solid image-pickup device and method for manufacturing the solid image pickup device

A pilot opening to the outside is formed at one side end of a package for a solid-state image-pickup device and a guide opening to the outside is formed at a side end opposite to and approximately in parallel with the one side end of the package. The pilot is made to face a pilot pin projecting above a circuit board and a guide pin is inserted into the guide. The solid-state image-pickup device is then fixed at a prescribed position on the circuit board after the pilot comes into contact with the pilot pin. With a solid-state-,image-pickup device and a mounting method thus provided, package size does not become large and mounting is carried out with an extremely high positioning precision.

Solid-state image-pickup device and method of mounting solid-state image-pickup device

A semiconductor device such as a solid state imaging device has a semiconductor chip mounted on a bottom surface of a cavity of a hermetic sealed box-shaped resin-molded package. The device comprises a radiator plate provided in a bottom wall of the package under the cavity or on the bottom surface of the cavity. The semiconductor chip and the radiator plate are bonded with an adhesive having a larger thermal conductivity than that of the resin forming the package. The radiator plate may be a part of a lead frame.
