Abstract:
1. A method for producing a power module having a first substrate populated with power semiconductor chips, and having a second substrate populated with signal semiconductor chips, the substrates in the power module being oriented parallel one above the other and their placement sides being arranged facing one another, and bonding wires bent in a hingelike manner electrically connecting the two placement sides to one another and defining the distance between the first and second substrates and mechanically fixing them, the method comprising: providing a first substrate populated with power semiconductor chips, and a second substrate populated with signal semiconductor chips; orientating the first substrate and second substrate such that their placement sides are arranged next to one another and edge regions of the placement sides of the two substrates that have bonding areas lie next to one another; connecting the first substrate and the second substrate at edge regions having bonding areas to bonding wires arranged next to one another in hinge-type fashion; folding over of the second substrate through 180° with bending of the bonding wires arranged in hinge-type fashion, so that the substrates are oriented parallel one above the other and the first placement side and the second placement side are arranged facing one another; and packaging of the power module in a plastic housing.
