An inventive leadframe includes an outer frame, a die pad, and a plurality of leads each having land portions and connections. The land portions each have an upper surface serving as a bonding pad to be connected with a metal wiring, and a lowermost part serving as an external terminal. The connections are each devoid of its lower part so as to be thinner than the land portion, and are provided between the outer frame and the land portions, between the land portions associated with each other in each lead, and between the land portions and the die pad. Furthermore, the inventive leadframe is provided with no member that functions as a suspension lead for connecting the outer frame and the die pad to each other during plastic encapsulation.

A method for producing a solid-state imaging device including a base of an insulation material having a frame form in planar shape with an aperture formed in an inner region thereof and having a substantially uniform thickness; a wiring provided on one surface of the base and extending toward the outside from the peripheral portion of the aperture; and an imaging element mounted on the surface of the base provided with the wiring so that a light-receptive region of the element faces the aperture. Cavities for resin-molding a plurality of the bases are formed and a tape member supporting thin metal plate leads for forming a plurality of sets of wirings corresponding to the respective bases is loaded between molds having pins for forming positioning holes of the base; and the thin metal plate leads are placed in the cavities. Then, a sealing resin is filled in the cavities and cured. A resin molded member, in which the thin metal plate leads are embedded, is taken out; and the tape member is removed from the resin molded member, and the resin molded member is divided into a plurality of pieces on which an imaging element is mounted. The base on which the imaging element is mounted can be formed to have a practically sufficient flatness.

A resin-encapsulated semiconductor device includes: a semiconductor chip on a surface of which a group of electrodes is disposed; a plurality of inner leads arranged along a periphery of the semiconductor chip; connecting members for connecting the electrodes of the semiconductor chip with the respective inner leads, an encapsulating resin for encapsulating surfaces of the semiconductor chip and the connecting members; and external electrodes exposed from the encapsulating resin. Each of the inner leads extends across the periphery of the semiconductor chip from an internal side to an external side of the periphery, and includes a protruded portion provided on a surface of the inner lead on an external side relative to the periphery of the semiconductor chip, the protruded portion being protruded in a thickness direction. Conductive bumps as the connecting members on the electrodes of the semiconductor chip are connected with internal portions of the respective inner leads, the internal portions being positioned inward relative to the protruded portions. The external electrodes are formed on surfaces of the protruded portions, and tip ends of the external electrodes are protruded relative to a back face of the semiconductor chip.

An optic device includes a base, an optical chip mounted on the base, and a transparent plate. A cylinder mirror in which an imaging optical system is incorporated is fitted on the base of the optic device, wherein a pair of positioning pins are provided at the bottom of the cylinder mirror. First positioning holes for defining a mounting position of the cylinder mirror to the base and second positioning holes having a smaller diameter than that of the first positioning holes for defining a mounting position of the optical chip to the base are formed in the base of the optic device.

A solid-state imaging device includes: a housing having a base and a rectangular-frame-shaped rib that are resin molded integrally; metal lead pieces embedded in the housing, each of which has an internal terminal portion facing an internal space, an external terminal portion exposed on a bottom face, and a side electrode portion exposed on an external side face; an imaging element fixed on the base; connection members connecting electrodes of the imaging element and the internal terminal portions of the metal lead pieces, respectively; and a transparent plate fixed on an upper end face of the rib. A thickness of each metal lead piece at a position of its internal terminal portion is substantially equal to a thickness of the base, and the external terminal portion is formed with a reverse face of the metal lead piece at a position corresponding to the internal terminal portion. In the resin molding, the internal terminal portion is pressed against the upper mold, whereby the occurrence of resin burrs is suppressed.

A lead frame is buried in mold resin to form a mold structure. A wide blade is used to make an indentation having an alignment step in the mold structure. Then, a narrow blade is used to split the mold structure. At the outer perimeter portion of a base which is a separate part separated from the mold structure, an alignment step is formed. Due to the alignment step, an optical element, such as a mirror tube of an imaging optical system, or the like, is readily and quickly attached.
