    摘要: The invention relates to a power module comprising a substrate (2), whose surfaces are provided with at least one electrically conductive layer (4, 6), at least one active semiconductor chip (8), which is electrically connected to an electrically conductive layer (6), a film (12) consisting of an electrically conductive material, which is in close contact with the surfaces of the semiconductor chips (8) of the electrically conductive layer (6) and the substrate (2) and is provided with planar printed conductors (16). According to the invention: the module is equipped with a second film (18), which is in close contact with the surfaces of the printed conductors (16) and the first film (12); a passive semiconductor chip (22) is applied to said second film (18), above the active semiconductor chip (8) and is electrically connected to the planar printed conductor (16) lying below by means of a window (14) that is configured in the second film (18); the module is equipped with a third film (24), which is in close contact with the surfaces of the passive semiconductor chip (22) and the second film (18) and said third film (24) is provided with a planar printed conductor (28), which is conductively connected to the conductive layer (6) lying below the active semiconductor chip (8). The invention thus provides a compact power module that can comprise complex topologies.
