Abstract
A semiconductor device having especially low thermal impedance between a semiconductor element and a heatsink is described wherein the semiconductor element is directly disposed upon a thin, low thermal impedance current-spreading layer on an electrically isolated layer. An electrode connected to the current-spreading layer surrounds the semiconductor element so that it introduces no additional thermal impedance between the semiconductor element and the heatsink. Relatively inexpensive electrode materials may be used in accordance with the invention without increasing thermal impedance.
