Abstract:
1. A semiconductor device, comprising: at least one heat dissipating fin element having at least one fin, wherein an upper surface of said at least one heat dissipating fin element has a protruding shape and/or recessed shape; an insulating sheet bonded to the upper surface of said at least one heat dissipating fin element, wherein the insulating sheet is provided at the upper surface of said at least one heat dissipating fin element at a position such that said protruding shape and/or recessed shape engages and binds an edge of said insulating sheet to fix the position of the insulating sheet on the upper surface of said at least one heat dissipating fin element, and wherein a part of the upper surface of said at least one heat dissipating fin element is exposed; a heat spreader located on said insulating sheet; a power element located on said heat spreader; and a transfer molding resin located to cover a predetermined surface including said part of the upper surface of said at least one heat dissipating fin element, said insulating sheet, said heat spreader and said power element.
