Abstract:
A semiconductor device, comprising:a semiconductor substrate having a heat generating region;first, second, and third electrodes formed on said semiconductor substrate:a plurality of first conductive fingers arranged in parallel with each other in said heat generating region, each of said first conductive fingers coupled to one of said first electrodes electrically;a plurality of second conductive fingers arranged in parallel with said first conductive fingers in said heat generating region, each of said second conductive fingers coupled to one of said second electrodes electrically, each of said second conductive fingers arranged between the respective ones of said first conductive fingers;a plurality of third conductive fingers arranged in parallel with said first conductive fingers in said heat generating region, each of said third conductive fingers coupled to one of said third electrodes electrically, each of said third conductive fingers arranged between one of the respective first conductive fingers and one of the respective second conductive fingers; anda heat radiator that makes temperature distribution in said heat generating region substantially uniform, wherein said heat radiator includes a plurality of metal plate electrodes formed on at least one of said first and second conductive fingers, each of said metal plate electrodes being in parallel with said first conductive fingers, and a first metal electrode of said plurality of metal plate electrodes arranged at a center portion of said heat generating region has a width which is wider than that of a second metal electrode of said plurality of metal plate electrodes arranged at a peripheral portion of said heat generating region.
