Abstract:
1. An electronic module with switching functions, the module comprising: a pair of integrated circuit chips arranged in a chip stack to provide the switching functions, wherein each of the integrated circuit chips comprises a first power electrode that is disposed on and completely covers a rear side of the integrated circuit chip, the rear sides of the integrated circuit chips facing toward each other, and each of the integrated circuit chips further comprises a second power electrode covering a majority of the surface of a top side of the integrated circuit chip and a small-area control electrode on the top side that has a smaller dimension than the second power electrode, the top sides of the integrated semiconductor chips facing away from each other; and a diffusion solder layer arranged between the first power electrodes disposed on the rear sides of the stacked chips, wherein the diffusion solder layer extends to edges of the chips.
