  • Publication number: 20140077366
    Abstract: A wafer level fan-out package with a fiducial die is disclosed and may include a semiconductor die and a transparent fiducial die both encapsulated in a molding compound resin, passivation layers on an upper surface and a lower surface of the molding compound resin except where redistribution layers are formed on upper and lower surfaces of the molding compound resin, and a metal pattern on a lower surface of the transparent fiducial die that is visible through an exposed upper surface of the transparent fiducial die. The pattern may comprise a standard coordinate for forming a through mold via utilizing laser drilling.

  • Publication number: 20140042600
    Abstract: A semiconductor package and manufacturing method thereof are disclosed and may include a first semiconductor device comprising a first bond pad on a first surface of the first semiconductor device, a first encapsulant material surrounding side edges of the first semiconductor device, and a redistribution layer (RDL) formed on the first surface of the first semiconductor device and on a first surface of the encapsulant material. The RDL may electrically couple the first bond pad to a second bond pad formed above the first surface of the encapsulant material. A second semiconductor device comprising a third bond pad on a first surface of the second semiconductor device may face the first surface of the first semiconductor device and be electrically coupled to the first bond pad on the first semiconductor device. The first surface of the first semiconductor device may be coplanar with the first surface of the encapsulant material.

  • Patent number: 8058726
    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.

  • Patent number: 7982316
    Abstract: A semiconductor package and method of fabricating has a substrate having conductive patterns formed thereon. A semiconductor die is attached to the substrate. An electrically connecting member is electrically coupled to the semiconductor die and the conductive patterns. A plurality of lands is coupled to the substrate. At least one land is pivotally mounted to the substrate. A first section of the pivotally mounted land is in contact with the substrate. A second section of the pivotally mounted land is floating to form a void area between the substrate and the second section. An encapsulant is used for encapsulating a top surface of the substrate, the semiconductor die, and the electrically connecting member. A solder ball is electrically coupled to each land.
