Patent ID: 7367120

Claim:
A method for producing a solid-state imaging device that comprises: a base made of an insulation material and having a frame form in planar shape with an aperture formed at an inner region; a plurality of wirings provided on one surface of the base and extending toward an outer periphery of the base from a region along the aperture; and an imaging element mounted on the face of the base with the plurality of wirings provided thereon so that a light-receptive region of the imaging element faces the aperture, wherein an end portion on the aperture side of each of the plurality of wirings forms an internal terminal portion and an end portion on the outer peripheral side of each of the plurality of wirings forms an external terminal portion, the internal terminal portion of the wiring being connected electrically with an electrode of the imaging element, the method comprising; using a pair of molds for forming cavities for molding the base, together with a lead frame having thin metal plate leads for forming the plurality of wirings and a reinforcing plate portion having a shape corresponding to a shape of the aperture of the base which is coupled to the thin metal plate leads in a semi-disconnected state at a boundary portion therebetween, placing the lead frame between the pair of molds so that the thin metal plate leads are positioned in the cavities formed with the pair of molds and so that the reinforcing plate portion is positioned at a portion where the aperture is to be formed; pouring a sealing resin in the cavities, followed by curing the sealing resin; taking a resin molded member formed in a shape of the base, in which the thin metal plate leads are embedded, out of the pair of molds; separating the reinforcing plate portion from the thin metal plate leads so as to obtain the base, and mounting the imaging element on a face of the base with the plurality of wirings provided thereon; wherein a recess for forming the cavities is formed in one of the pair of molds, and a deflashing sheet is interposed between the other mold and the lead frame when molding the base.
