  • Patent number: 11296000
    Abstract: An electronic circuit includes a first packaged semiconductor device having a first semiconductor die including a first terminal, a first electrically conductive lead that is electrically connected to the first terminal, and a first electrically insulating mold compound that encapsulates the first semiconductor die and exposes an end portion of the first lead at an outer surface of the first mold compound. A conductive track is formed in the outer surface of the first mold compound.

  • Patent number: 11217511
    Abstract: A packaged semiconductor device includes a carrier having a die attach surface, a semiconductor die mounted on the die attach surface and comprising first and second conductive terminals disposed on an upper side, a first clip that extends over the semiconductor die and is electrically connected to the first conductive terminal, a second clip that extends over the semiconductor die and is electrically connected to the second conductive terminal, and an electrically insulating encapsulant body that encapsulates the semiconductor die. An outer end of the first clip is exposed from the encapsulant body and provides a point of external electrical contact for the first conductive terminal. An outer end of the second clip is exposed from the same or a different side face of the encapsulant body as the first clip and provides a point of external electrical contact for the second conductive terminal.

  • Patent number: 10741466
    Abstract: A first packaged semiconductor device is provided. The first packaged semiconductor device includes a first semiconductor die having a first terminal, a first electrically conductive lead that is electrically connected to the first terminal, and a first electrically insulating mold compound that encapsulates the first semiconductor die and exposes an end portion of the first lead at an outer surface of the first mold compound. A conductive track is formed in the outer surface of the first mold compound. Forming the conductive track includes activating a portion of the outer surface of the first mold compound for an electroless plating process, and performing the electroless plating process so as to form an electrically conductive material only within the activated portion of the outer surface of the first mold compound.

  • Patent number: 10325837
    Abstract: A semiconductor package includes a semiconductor die embedded in a molded package body, leads electrically connected to the die and protruding from a side face of the molded package body, and a recess extending inward from the side face and into a bottom main face of the molded package body to forma single groove. The recess begins below a region of the side face from which the leads protrude, so that this region of the side face is flat and each of the leads exits the molded package body in the same plane. A first subset of the leads is bent inward towards the molded package body and seated in the single groove, to form a first row of leads configured for surface mounting. A second subset of the leads extends outward from the molded package body, to form a second row of leads configured for surface mounting.
