  • Patent number: 7138706
    Abstract: A semiconductor device with excellent heat dissipation characteristics that can achieve a high reliability when mounted in electronic equipment such as a cellular phone or the like and a method for manufacturing the same are provided. The semiconductor device includes a substrate, a plurality of semiconductor chips mounted on the substrate by stacking one on top of another, and an encapsulation resin layer made of encapsulation resin. Among the plurality of semiconductor chips, a first semiconductor chip as an uppermost semiconductor chip is mounted with a surface thereof on which a circuit is formed facing toward the substrate, and the encapsulation resin layer is formed so that at least a surface of the first semiconductor chip opposite to the surface on which the circuit is formed and a part of side surfaces of the first semiconductor chip are exposed to the outside of the encapsulation resin layer.

  • Publication number: 20060208349
    Abstract: A semiconductor device and a manufacturing method for the same are provided wherein the reliability of connections of fine metal wires connecting a second semiconductor chip to a wiring board can be improved in the case wherein the second semiconductor chip, which is located above the lower, first semiconductor chip, is significantly larger than the first semiconductor chip in a configuration wherein two semiconductor chips are stacked and mounted on a wiring board. In this semiconductor device the rear surface of the first semiconductor chip and the rear surface of the second semiconductor chip are adhered to each other by means of adhesive and the side of the adhesive is inclined from the edge portions of the first semiconductor chip toward the portions of the second semiconductor chip extending from the side of the first semiconductor chip.
