Abstract:
1. A power semiconductor module, comprising: a circuit carrier including an insulation carrier having a top side on which a metallization layer is arranged; a power semiconductor chip arranged on a side of the metallization layer facing away from the insulation carrier, and which has, on a top side of the power semiconductor chip facing away from the circuit carrier, an upper chip metallization composed of copper or a copper alloy having a thickness of greater than or equal to 1 μm; an electrical connection conductor composed of copper or a copper alloy connected to the upper chip metallization at a connecting location; and a potting compound which extends from the circuit carrier to at least over the top side of the power semiconductor chip, completely covers the top side of the power semiconductor chip, and encloses the connection conductor at least in the region of the connecting location, wherein the potting compound is a one-component potting material or a multi-component potting material; wherein the one-component potting material is selected from the group consisting of: a silicone resin, and an epoxy resin; wherein one of the components in the multi-component potting material is selected from the group consisting of: a silicone-gel, an internal adhesion promoter, a silicone resin, and an epoxy resin, and wherein the compound ingredients of the multi-component potting material form a uniform potting compound that contacts the power semiconductor chip and the electrical connection conductor.
