  • Patent number: 10143084
    Abstract: A plated hole with a sidewall plating. The plated hole has a vent opening that has a sidewall of non-conductive material that is not plated. During attachment of a joint conductive material such as solder to the sidewall plating, gasses generated from the attachment process are outgassed through the vent opening.

  • Patent number: 10083912
    Abstract: A package substrate having an opening and through-substrate interconnect structures is attached to a temporary carrier such as an adhesive film. The active surface of an IC die is placed in contact with the carrier substrate within the opening, to temporarily attach the die to the carrier substrate. Another die is attached to the side of the first die furthest from the carrier substrate. In one embodiment, the dies are attached to each other using an epoxy so that their respective non-active surfaces face each other. Bond wires are connected between interconnects at the active surface of the second die and the substrate. The wires are then encapsulated. After removal of the carrier substrate, a build-up interconnect structure is formed that includes external interconnects of the package substrate, such as solder balls of a ball grid array package.

  • Patent number: 9899298
    Abstract: Methods for fabricating microelectronic packages, such as Fan-Out Wafer Level Packages, and microelectronic packages are provided. In one embodiment, the method includes placing a first semiconductor die on a temporary substrate, forming an electrically-conducive trace in contact with at least one of the first semiconductor die and the temporary substrate, and encapsulating the first semiconductor die and the electrically-conductive trace within a molded panel. The temporary substrate is removed to reveal a frontside of the molded panel through which the electrically-conducive trace is at least partially exposed. At least one redistribution layer is formed over the frontside of the molded panel, the at least one redistribution layer comprises an interconnect line in ohmic contact with the electrically-conducive trace.

  • Publication number: 20170200701
    Abstract: A method of fabricating a 3D fan-out structure for an integrated circuit device includes providing a substrate carrier having first and second opposing surfaces and an aperture extending between the first and second surfaces. A first semiconductor die is bonded to the first surface of the substrate carrier such that the first die covers the aperture of the substrate carrier. An encapsulant and a second die are deposited within the aperture of the substrate carrier such that an active surface of the second die is exposed and coplanar with the second surface of the substrate carrier. One or more redistribution layers are then applied on the second surface of the substrate carrier to form a 3D fan-out structure.

  • Publication number: 20170053862
    Abstract: A method for making a packaged semiconductor device includes dispensing a first adhesive into a first cavity of a substrate having a first major surface and a second major surface. The first cavity extends into the substrate from the second major surface. The method further includes placing a first component having a thickness less than a thickness of the substrate into the first cavity such that the first adhesive physically contacts a first major surface of the first component and at least partially fills a gap between sidewalls of the first component and sidewalls of the first cavity. After placing the first component, a second major surface of the first component is coplanar with the second major surface of the substrate.
