  • Patent number: 9680008
    Abstract: A transistor advantageously embodied in a laterally diffused metal oxide semiconductor device having a gate located over a channel region recessed into a semiconductor substrate and a method of forming the same. In one embodiment, the laterally diffused metal oxide semiconductor device includes a source/drain having a lightly doped region located adjacent the channel region and a heavily doped region located adjacent the lightly doped region. The laterally diffused metal oxide semiconductor device further includes an oppositely doped well located under and within the channel region, and a doped region, located between the heavily doped region and the oppositely doped well, having a doping concentration profile less than a doping concentration profile of the heavily doped region.

  • Patent number: 8153473
    Abstract: A module having a discrete passive element and a semiconductor device, and method of forming the same. In one embodiment, the module includes a patterned leadframe, a discrete passive element mounted on an upper surface of the leadframe, and a thermally conductive, electrically insulating material formed on an upper surface of the discrete passive element. The module also includes a semiconductor device bonded to an upper surface of the thermally conductive, electrically insulating material.
