Claim:
1. A surface mountable semiconductor device comprising: at least one semiconductor element mounted on or integrated in a device substrate, the device substrate having a top surface and a bottom surface, the top surface being proximate to the at least one semiconductor element and the bottom surface being distal from the at least one semiconductor element, one or more electrical connection pads distinct from the device substrate, the one or more electrical connection pads being arranged on the bottom surface of the device substrate, the one or more electrical connection pads having a first height, and at least one thermal pad distinct from the device substrate, the at least one thermal pad being arranged on the bottom surface of the device substrate, the at least one thermal pad having a second height that is larger than the first height of the one or more electrical connection pads, wherein the surface mountable semiconductor device is surface mountable through an electrical connection through a bottom of the one or more electrical connection pads, wherein the at least one thermal pad is separated from the one or more electrical connection pads by a trench or gap and the trench or gap is filled with an electrically insulating material.
