  • Patent number: 8114709
    Abstract: A lead frame facilitates the handling, positioning, attachment, and/or continued integrity of multiple dies, without the use of multiple separate parts, such as jumpers. The lead frame includes a number of structures, each of which is attached to at least one lead. At least one receiving surface, arranged to receive a die, is associated with each structure. When dies are disposed on the receiving surfaces, anodes are similarly-oriented. A number of fingers are attached to the lead frame, and one or more electrode contact surfaces are attached to each finger. Each electrode contact surface can be positioned (for example, bent) with respect to one receiving surface, to facilitate electrical connection between the anode of a die and a lead. The lead frame may be used in connection with surface- and through-hole-mountable electronic devices, such as bridge rectifier modules.

  • Publication number: 20070013053
    Abstract: A semiconductor device mountable to a substrate includes: a semiconductor die; an electrically conductive attachment region having a first attachment surface and a second attachment surface, the first attachment surface arranged for electrical communication with the semiconductor die; an interface material having a first interface surface and a second interface surface, the first interface surface in contact with the second attachment surface of the electrically conductive attachment region; a thermally conductive element in contact with the second interface surface; and a housing at least in part enclosing the semiconductor die and affixed to the thermally conductive element. The thermally conductive element and the housing form exterior packaging of the semiconductor device. Heat is removable from the semiconductor die to the exterior packaging via a thermal conduction path formed by the electrically conductive attachment region, the interface material, and the thermally conductive element.
