  • Patent number: 7825506
    Abstract: A semiconductor module and a method for producing the same is disclosed. In one embodiment, the semiconductor module has adjacent regions on a common wiring substrate in a common plastic housing composition. The regions are thermally decoupled by a thermal barrier. Semiconductor chips whose evolution of heat loss differs are arranged in these thermally separate regions, the thermal barrier ensuring that the function of the more thermally sensitive semiconductor chip is not impaired by the heat-loss-generating semiconductor chip.

  • Patent number: 7355858
    Abstract: A heat sink for surface-mounted semiconductor devices is provided on a superordinate circuit board of an electronic module. The heat sink includes a three-dimensionally structured thermally conductive plate with a press-on region and snap-action hooks. The snap-action hooks are arranged approximately at right angles with respect to the press-on region and are spring-elastically connected to the press-on region of the heat sink via a spring-elastic connecting region of the heat sink. The snap-action hooks engage with edge regions of a thermally conductive coupling plate with the press-on region generating pressure. The coupling plate is fixed to a rear side of a semiconductor chip of the surface-mounted semiconductor device.
