  • Patent number: 8558368
    Abstract: Embodiments of the present invention relate to an improved package for a bi-directional and reverse blocking battery switch. According to one embodiment, two switches are oriented side-by-side, rather than end-to-end, in a die package. This configuration reduces the total switch resistance for a given die area, often reducing the resistance enough to avoid the use of backmetal in order to meet resistance specifications. Elimination of backmetal reduces the overall cost of the die package and removes the potential failure modes associated with the manufacture of backmetal. Embodiments of the present invention may also allow for more pin connections and an increased pin pitch. This results in redundant connections for higher current connections, thereby reducing electrical and thermal resistance and minimizing the costs of manufacture or implementation of the die package.

  • Patent number: 8110915
    Abstract: An RF semiconductor package includes a substrate having generally planar top and bottom surfaces. The substrate includes a metallic base region and one or more metallic signal terminal regions extending from the top surface to the bottom surface, and an insulative material separating the metallic regions from one another. The bottom surface of an RF semiconductor die is surface-mounted to the base region at the top substrate surface. The RF semiconductor die has a terminal pad disposed at a top surface of the RF semiconductor die. The terminal pad is electrically connected to one of the signal terminal regions at the top substrate surface. A lid is attached to the top substrate surface so that the RF semiconductor die is enclosed by the lid to form an open-cavity around the RF semiconductor die. The base and signal terminal regions are configured for surface-mounting at the bottom substrate surface.

  • Patent number: 8106508
    Abstract: The electric component includes at least a set of electrode terminals 2, 3, a semiconductor element 4 electrically connected with the set of electrode terminals, and a package 6 made of synthetic resin and sealing the electrode terminals and the semiconductor element with part of a lower surface of each of the electrode terminals exposed at a lower surface of the package. A cover layer 11 made of synthetic resin is formed to cover a cut surface of a tip of a connector lead remainder extending integrally outward from the each of the electrode terminals. Thus, disadvantages resulting from exposure of the cut surface of the tip of the connector lead remainder are eliminated.

  • Patent number: 8097898
    Abstract: The outer peripheral portion of a substrate is provided with a first peripheral edge and a second peripheral edge. The first peripheral edge is provided on the edge portion of a first upper surface of the substrate on which a light-emitting diode element is mounted. The second peripheral edge is formed either on an extension of an imaginary line connecting an edge of the light-emitting facet of the light-emitting diode element and the first peripheral edge or inwardly of the extension. The second peripheral edge is located at a position where the first peripheral edge blocks direct light from the light-emitting diode element. This configuration prevents the second upper surface of the substrate provided between the first peripheral edge and the second peripheral edge from becoming deteriorated due to the direct light.

  • Patent number: 8097945
    Abstract: Embodiments of the present invention relate to an improved die layout for a bi-directional and reverse blocking battery switch. According to one embodiment, two switches are oriented side-by-side, rather than end-to-end, in a die package. This configuration reduces the total switch resistance for a given die area, often reducing the resistance enough to avoid the use of backmetal in order to meet resistance specifications. Elimination of backmetal reduces the overall cost of the die package and removes the potential failure modes associated with the manufacture of backmetal. Embodiments of the present invention may also allow for more pin connections and an increased pin pitch. This results in redundant connections for higher current connections, thereby reducing electrical and thermal resistance and minimizing the costs of manufacture or implementation of the die package.

  • Patent number: 8063470
    Abstract: A leadframe for use in fabricating a no lead semiconductor package contains connecting bars between individual electrical contact pads. For embodiments having a die pad, the leadframe further includes connecting bars between the contact pads and the die pad. The lower surfaces of the connecting bars are coplanar with the lower surfaces of the contact pads and/or the die pad, and the upper surfaces of the connecting bars are recessed with respect to the upper surfaces of the contact pads and/or the die pad. The semiconductor package is fabricated by encapsulating the die and the leadframe in a molding compound and then removing the connecting bars. The leadframe is typically formed by half etching a metal sheet to form the connecting bars. The connecting bars are removed from the encapsulated package by a selected cutting, sawing, or etching means, based on a predetermined pattern.
