    Abstract: A power semiconductor die includes a substrate and a drift layer on the substrate. The drift layer includes an active area, an edge termination area surrounding the active area, and a thermal dissipation area surrounding the edge termination area. The thermal dissipation area is configured to reduce a thermal resistance of the power semiconductor die. By providing the thermal dissipation area, the operating voltage and/or current of the power semiconductor die can be increased without an increase in the active area. Further, the manufacturing yield of the power semiconductor die can be improved.
