  • Publication number: 20160133601
    Abstract: A semiconductor product in the form of a stack chip package and a method of manufacturing the same, where a plurality of semiconductor chips are stacked one on another so as to enable the exchange of electrical signals between the semiconductor chips, and where a conductive layer is included for inputting and outputting signals to and from individual chips. A stack chip package having a compact size may, for example, be manufactured by stacking, on a first semiconductor chip, a second semiconductor chip having a smaller surface area by means of interconnection structures so as to enable the exchange of electrical signals between the first and second semiconductor chips, and by using a conductive layer for inputting and outputting signals to and from individual semiconductor chips, in lieu of a thick substrate. Furthermore, heat dissipation effects can be enhanced by the addition of a heat dissipation unit.

  • Patent number: 9123543
    Abstract: A semiconductor device and method of manufacturing the same are provided. The semiconductor device comprises a semiconductor die including a bond pad, a redistribution layer, and a solder ball. The redistribution layer is formed by sequentially plating copper and nickel, sequentially plating nickel and copper, or sequentially plating copper, nickel, and copper. The redistribution layer includes a nickel layer in order to prevent a crack from occurring in a copper layer. Further, a projection is formed in an area of the redistribution layer or a dielectric layer to which the solder ball is welded and corresponds, so that an area of the redistribution layer to which the solder ball is welded increases, thereby increasing bonding power between the solder ball and the redistribution layer.
