摘要:
An optical apparatus includes an optical device (LED device or semiconductor imaging device) having a photoreceptor/light-emitting region, a peripheral circuit region and an electrode region, a transparent member having a larger light passing through region than the optical device and including, on one surface thereof, protruding electrodes for connection to the optical device, external connection electrodes for connection to a mounting substrate, conductive interconnects for connecting the protruding electrodes and the external connection electrodes, and a transparent adhesive provided between the optical device and the transparent member. In the optical apparatus, one surface of the optical device in which the photoreceptor/light-emitting region is formed and one surface of the transparent member are arrange so as to face to each other and electrodes of the optical device and the protruding electrodes of the transparent member are electrically connected and also adhered by the transparent adhesive.

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.

An optical semiconductor device includes: a package having a bottom portion and a sidewall portion; a semiconductor chip having an optical element formed on one surface thereof and having an opposite surface to the one surface fixed to the bottom portion of the package; a transparent member fixed to the semiconductor chip so as to cover the optical element; and a sealing resin filling a space between the package and the semiconductor chip. The sidewall portion has in an upper part thereof an overhang portion that projects toward inside of the package. The transparent member is exposed from a window portion formed by the overhang portion.
