  • Patent number: 11817407
    Abstract: A molded semiconductor package includes: a semiconductor die attached to a substrate, the semiconductor die having a bond pad at a first side of the semiconductor die which faces away from the substrate and an insulating layer covering the first side; an electrical conductor attached to a part of the bond pad exposed by an opening in the insulating layer; a mold compound encasing the semiconductor die; and an electrically insulative material filling the opening in the insulating layer and sealing the part of the bond pad exposed by the opening in the insulating layer. The electrically insulative material separates the mold compound from the part of the bond pad exposed by the opening in the insulating layer. A corresponding method of producing the molded semiconductor package also is described.

  • Patent number: 11444011
    Abstract: An embodiment of a semiconductor package includes a leadframe having leads, a mold compound partly encasing the leadframe so that the leads protrude from the mold compound, a power transistor die attached to the leadframe at a first side of the leadframe, and a driver die attached to the leadframe at a second side of the leadframe opposite the first side so that the power transistor die and the driver die are disposed in a stacked arrangement. The driver die is configured to control the power transistor die. The driver die is in direct electrical communication with the power transistor die only through the leadframe and any interconnects which attach the power transistor die and the driver die to the leadframe. Corresponding methods of manufacturing the semiconductor package are also described.

The electrically insulative material separates the mold compound from the part of the bond pad exposed by the opening in the insulating layer. A breakdown voltage of the electrically insulative material is greater than a breakdown voltage of the mold compound.

  • Patent number: 10872848
    Abstract: An embodiment of a semiconductor package includes a leadframe and a mold compound partly encasing the leadframe so that leads protrude from the mold compound and at least two die pads have a surface at a first side of the leadframe which is not covered by the mold compound. A laser module is attached to the surface of the at least two die pads which is not covered by the mold compound. A driver die is attached to the leadframe at a second side of the leadframe opposite the first side so that the laser module and the driver die are disposed in a stacked arrangement, the driver die configured to control the laser module. The driver die is in direct electrical communication with the laser module only through the leadframe and any interconnects which attach the laser module and driver die to the leadframe.
