  • Patent number: 10770399
    Abstract: A semiconductor package includes a frame having an insulative body with a first main surface and a second main surface opposite the first main surface, a first plurality of metal traces at the first main surface, and a first cavity in the insulative body. A thermally and/or electrically conductive material filling the first cavity in the insulative body and having a different composition than the first plurality of metal traces. The thermally and/or electrically conductive material provides a thermally and/or electrically conductive path between the first and the second main surfaces of the insulative body. A semiconductor die attached to the frame at the first main surface of the insulative body is electrically connected to the first plurality of metal traces and to the thermally and/or electrically conductive material filling the first cavity in the insulative body. A corresponding method of manufacture is also described.

  • Publication number: 20200273781
    Abstract: A molded semiconductor package includes a lead frame having one or more first leads monolithically formed with a die pad and extending outward from the pad in a first direction. A semiconductor die is attached to the die pad at a first side of the die. A metal clip of a clip frame is attached to a power terminal at a second side of the die. One or more second leads monolithically formed with the metal clip extend outward from the clip in a second direction different than the first direction. A mold compound embeds the die. The first lead(s) and the second lead(s) are exposed at different sides of the mold compound and do not vertically overlap with one another. Within the mold compound, the clip transitions from a first level above the power terminal to a second level in a same plane as the leads.

  • Patent number: 7498194
    Abstract: The invention relates to a vertical arrangement of at least two semiconductor components which are electrically insulated from one another by at least one passivation layer. The invention likewise relates to a method for fabricating such a semiconductor arrangement. A semiconductor arrangement is specified in which, inter alia, the risk of cracking at the metallization edges, for example, caused by thermomechanical loading, is reduced and the fabrication-dictated high content of radical hydrogen is minimized. Furthermore, a method for fabricating such a semiconductor arrangement is specified.
