  • Patent number: 8664780
    Abstract: A semiconductor package includes a first semiconductor chip mounted to a substrate, a first encapsulant covering the first semiconductor chip and have first to fourth sidewall surfaces, and a chip stack mounted to the substrate and disposed on the first encapsulant. The chip stack includes a plurality of second semiconductor chips. A second encapsulant covers the chip stack. The second encapsulant may cover the first sidewall surface of the first encapsulant and expose the third sidewall surface of the first encapsulant.
    Type: Grant

  • Patent number: 8063313
    Abstract: A printed circuit board (PCB) and a semiconductor package that are configured to prevent delamination and voids. In one example embodiment, the semiconductor package includes a PCB having a base substrate on which conductive patterns are formed and which includes an interior region having a die paddle for receiving a semiconductor chip and an exterior region disposed outside the interior region. The PCB also includes a first solder resist formed on a portion of the base substrate corresponding to the interior region and a second solder resist formed on a portion of the base substrate corresponding to the exterior region. The second solder resist may also have a greater surface roughness than the surface roughness of the first solder resist.
