A resin-encapsulated semiconductor device includes a semiconductor chip, a plurality of inner leads that are connected to a group of electrodes of the semiconductor chip, respectively, and an encapsulating resin that encapsulates a connection part located between the semiconductor chip and the inner leads. Each of the inner leads includes a protruded portion provided on a surface thereof on an outer side relative to the periphery of the semiconductor chip. The protruded portion protrudes in a thickness direction and is provided with a step portion formed in its side portion. The group of electrodes of the semiconductor chip is connected to surfaces of inner portions of the inner leads located on an inner side relative to their protruded portions, through electroconductive bumps, respectively. The encapsulating resin encapsulates the semiconductor chip and the electroconductive bumps and is formed to expose surfaces of the protruded portions. The surfaces of the protruded portions that function as external terminals can be reduced in size and thereby the pitch between the external terminals can be reduced.

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 semiconductor device includes: a wiring substrate; a wiring electrode; a semiconductor chip; a connecting member; a resin encapsulant; and a mark member. The wiring electrode is formed on the wiring substrate. The semiconductor chip is mounted on the wiring substrate. An electrode pad formed on the semiconductor chip and the wiring electrode are electrically connected to each other with the connecting member. The semiconductor chip, the wiring electrode, and the connecting member, for example, are molded with the resin encapsulant on the upper surface of the wiring substrate. The mark member is embedded in the upper surface of the resin encapsulant. The mark member, which is transferred from a transfer sheet in a single process step, is highly visible and can be formed efficiently.

An optical element mounted on a wiring board is sealed by a sealing resin except an optical function region. Wires connecting the wiring board with the optical element are also sealed by the sealing resin. The optical function region is exposed as a bottom surface of a recess whose side surface is formed by the sealing resin. A boundary portion between the side surface of the recess and a top surface portion and a boundary portion between the side surface and bottom surface of the recess have a rounded shape.

A solid-state imaging-device includes a base, frame-shaped ribs provided on the base and forming an internal space, a plurality of wiring members for electrically leading the internal space of a housing formed by the base and the ribs to an external portion, an imaging element fixed to the base inside the internal space, a transparent plate fixed to an upper surface of the ribs, and connecting members electrically connecting electrodes of the imaging element to the wiring members, wherein a plurality of protrusions are provided in a region of the base that faces the imaging element, and the imaging element is fixed by adhesive to the base while being supported by the protrusions. The protrusions enable the imaging element to avoid distortion caused by following the surface of the base, thereby suppressing the effect on electrical properties of the imaging element.
