  • Patent number: 9048199
    Abstract: A semiconductor package and a method of manufacturing the semiconductor package are disclosed. A semiconductor package in accordance with an embodiment of the present invention includes a substrate, which has a ground circuit formed thereon, a semiconductor chip, which is mounted on the substrate, a conductive first shield, which is formed on an upper surface of the semiconductor chip and connected with the ground circuit, and a conductive second shield, which covers the substrate and the semiconductor chip and is connected with the first shield.

  • Patent number: 8779580
    Abstract: An electronic component package and a manufacturing method thereof are disclosed. The electronic component package manufacturing method, which includes mounting an electronic component in one surface of a first insulation layer; bonding a heat sink to the one surface of the first insulation layer, corresponding to the electronic component, to cover the electronic component, the heat sink being formed with a cavity; charging the cavity with an adhesive; and forming a circuit pattern in the other surface of the first insulation layer, can prevent a void from being generated in the adhesive, make the handling stable and make the size small by allowing the heat sink formed with the cavity to cover the electronic component before the pattern build-up and supplying the adhesive through one side of the cavity while providing negative pressure through the other side.
