  • Publication number: 20140077382
    Abstract: A semiconductor package can include a substrate body having a first surface and a second surface. A semiconductor chip can be mounted on the first surface and a plurality of electrode pads can be on the second surface and selectively formed to have progressively smaller or larger sizes extending from a central region of the substrate body toward an outer edge of the substrate body based on a reflow soldering process warpage profile for the semiconductor package.

  • Publication number: 20130334708
    Abstract: A stacked semiconductor package has a first semiconductor package including a first package substrate and a first semiconductor chip mounted on the first package substrate, a second semiconductor package including a second package substrate and a second semiconductor chip mounted on the second package substrate, and a plurality of connections electrically connecting the first and second semiconductor packages. The connections are disposed on an outer region of the first package substrate outside the first semiconductor chip. The connections are disposed along opposite first longer sides and opposite shorter second sides of the first package substrate. The heights of those connections disposed along each longer first side gradually vary from a central to an outer region (i.e., the ends) of the longer first side.

  • Patent number: 7868443
    Abstract: A vertical stack type multi-chip package is provided having improved reliability by increasing the grounding performance and preventing the decrease in reliability of the multi-chip package from moisture penetration into a lower semiconductor chip. The vertical stack type multi-chip package comprises an organic substrate having a printed circuit pattern on which a semiconductor chip is mounted. A first semiconductor chip is mounted on a die bonding region of the organic substrate and is electrically connected to the organic substrate through a first wire. A metal stiffener is formed on the first semiconductor chip and connected to the organic substrate by a first ground unit around the first semiconductor chip. An encapsulant is used to seal the first semiconductor chip below the metal stiffener. A second semiconductor chip, which is larger in size than that the first semiconductor chip, is mounted on the metal stiffener and connected by a second ground unit.
