摘要： A resin molded type semiconductor device has: a semiconductor chip (12) which is mounted on a die pad portion (11) of a lead frame (9); thin metal wires (14) which connect terminals of the semiconductor chip (12) to inner lead portions (13) of the lead frame (9); and a sealing resin (15), and the lead frame (9) is subjected to an upsetting process so that a supporting portion (11) is located at a position higher than the inner lead portions (13). Since the sealing resin of a thickness corresponding to the step difference of the upsetting exists below the supporting portion, the adhesiveness between the lead frame and the sealing resin can be improved, and high reliability and thinning are realized. Since at least one groove portion is disposed in the surface of each of the inner lead portions (13), the anchoring effect to the sealing resin (15), stress acting on a lead portion of a product, and stress to the thin metal wires (14) can be relaxed, and leads and the thin metal wires can be prevented from peeling off.

摘要： A semiconductor device has an external wiring for GND formed over an underside surface of a wiring substrate. A plurality of via holes connecting to the external wiring for GND are formed to penetrate the wiring substrate. A first semiconductor chip of high power consumption, including HBTs, is mounted over a principal surface of the wiring substrate. The emitter bump electrode of the first semiconductor chip is connected in common with emitter electrodes of a plurality of HBTs formed in the first semiconductor chip. The emitter bump electrode is extended in a direction in which the HBTs line up. The first semiconductor chip is mounted over the wiring substrate so that a plurality of the via holes are connected with the emitter bump electrode. A second semiconductor chip lower in heat dissipation value than the first semiconductor chip is mounted over the first semiconductor chip.

摘要： The present invention realizes strengthening of a ground of a lower-surface ground electrode of an upper semiconductor chip and miniaturization in a semiconductor module on which two semiconductor chips are mounted in a stacked manner. A lower semiconductor chip is fixed to a bottom of a recess formed in an upper surface of a module board, and an upper semiconductor chip is fixed to an upper surface of a support body made of conductor which is formed over the upper surface of the module board around the recess. External electrode terminals and a heat radiation pad are formed over a lower surface of the module board.

摘要： A surface light source apparatus is constituted such that an overhang portion overhanging a light source is provided on part of an end surface where the light source of an optical guide plate is arranged in such a manner that it is flush with the front surface of the optical guide plate and that an incident light control unit formed from a resin for diffusing and attenuating light is provided integratedly on at least an overhang portion side out of the overhang portion and the end surface of the optical guide plate, and accordingly light from the light source is transmitted through the overhang portion, radiated in an illumination direction, and diffused and attenuated by the incident light control unit to equalize the amount of light so that it can be used as illumination light. Thereby, the total area of the light emitting portions is increased.
