    Abstract: There is provided a semiconductor device including a substrate whose surface is made of an insulation material, a semiconductor chip flip-chip connected on the substrate, and a heat sink bonded to the semiconductor chip via a thermal interface material and fixed to the substrate outside the semiconductor chip, in which the heat sink has a protrusion part protruding toward the substrate and bonded to the substrate via a conductive resin between a part bonded to semiconductor chip and a part fixed to the substrate and the heat sink has a stress absorbing part. According to the present invention, the protrusion part of the heat sink is prevented from being peeled off from the substrate at the part where the protrusion part of the heat sink is bonded to the substrate.

    Abstract: A packaged electronic device includes a substrate comprising a die pad and a lead spaced apart from the die. An electronic device is attached to the die pad top side. A conductive clip is connected to the substrate and the electronic device, and the conductive clip comprises a plate portion attached to the device top side with a conductive material, a clip connecting portion connected to the plate portion and the lead, and channels disposed to extend inward from a lower side of the plate portion above the device top side. The conductive material is disposed within the channels. In another example, the plate portion comprises a lower side having a first sloped profile in a first cross-sectional view such that an outer section of the first sloped profile towards a first edge portion of the plate portion is spaced away from the electronic device further than an inner section of the first sloped profile towards a central portion of the plate portion. Other examples and related methods are also disclosed herein.
