  • Patent number: 8618657
    Abstract: A semiconductor device includes a semiconductor chip of a multilayer wiring structure having an insulating film formed on a surface thereof, multiple electrode pads formed at a central part and an outer peripheral part of the insulating film, and multiple protective metal layers formed respectively on the electrode pads. The semiconductor device also includes a substrate having the semiconductor chip mounted thereon and including multiple substrate terminals formed on a surface thereof respectively in positions corresponding to the electrode pads. The semiconductor chip is mounted on the substrate by connecting a stud bump to a solder bump. The stud bump is formed on any one of each of the protective metal layers and each of the substrate terminals and the solder bump is formed on the other one of each of the protective metal layers and each of the substrate terminals.

  • Patent number: 7148529
    Abstract: A semiconductor package includes (a) an interposer, (b) a wiring layer containing conductors formed adjacent to each other at intervals that cause no short circuit among the conductors, the wiring layer covering a given area of the interposer, to block light from passing through the given area, (c) a light blocking layer covering a no-wiring area of the interposer not covered by the wiring layer, to block light from passing through the no-wiring area, (d) a semiconductor chip electrically connected to the wiring layer, and (e) a resin mold sealing the wiring layer, the light blocking layer, and the semiconductor chip.
