Abstract
Abstract Method of cooling electronic systems an semiconductor devices as well as an electronic system and a semiconductor device with heat dissipating elements. The method includes the steps of providing an electronic system or a semiconductor device with a heat sink including at least a first element having a generally flat shape with a shoulder projecting from one generally flat surface, and configured to thermally engage similar elements. In one embodiment, a first and a second heat sink element are provided, with one of the first and second elements having a protrusion and the other of the first and second elements defining a depression configured to receive and retain said protrusion. Alternatively, the first and second elements may be bonded together with a thermally conductive adhesive.
