    Abstract: A molded power package includes a laser-activatable mold compound having laser-activated regions which are plated with an electrically conductive material to form metal pads and/or metal traces at a first side of the mold compound. A semiconductor power die with bond pads is embedded in the laser-activatable mold compound. A bond pad interconnect electrically connects the bond pads of the semiconductor power die to the metal pads and/or metal traces at the first side of the laser-activatable mold compound. The semiconductor power die is mounted on a carrier section of a leadframe. A carrier interconnect section of the leadframe integral with the carrier section electrically connects the carrier section to the metal pads and/or metal traces at the first side of the laser-activatable mold compound. An upper surface of the carrier interconnect section is at a height that is elevated relative to an upper surface of the carrier section.

  • Patent number: 11984392
    Abstract: A semiconductor package includes: a carrier having an electrically insulative body and a first contact structure at a first side of the electrically insulative body; and a semiconductor die having a first pad attached to the first contact structure of the carrier, the first pad being at source or emitter potential. The first pad is spaced inward from an edge of the semiconductor die by a first distance. The semiconductor die has an edge termination region between the edge and the first pad. The first contact structure of the carrier is spaced inward from the edge of the semiconductor die by a second distance greater than the first distance such that an electric field that emanates from the edge termination region in a direction of the carrier during normal operation of the semiconductor die does not reach the first contact structure of the carrier. Methods of production are also provided.
