Claim 15:
16. A method for fabricating a power electronics module, the method comprising:
providing at least one first substrate comprising a first side with one or more first semiconductor dies and a second side opposite the first side;
providing at least one second substrate comprising a first side with one or more second semiconductor dies and a second side opposite the first side;
providing a baseplate comprising a first side and a second side opposite the first side, the second side configured to directly contact a cooling fluid in a fluid channel of a heat sink;
providing at least one of a thermal gap pad or a layer of a thermal interface material, a lower surface of the at least one the thermal gap pad or the layer of the thermal interface material configured to be brought into contact with a wall of the heat sink;
arranging the baseplate below the at least one first substrate such that the first side of the baseplate faces the second side of the at least one first substrate;
arranging the thermal gap pad below the at least one second substrate or applying the layer of the thermal interface material to the second side of the at least one second substrate;
arranging the at least one first substrate and the at least one second substrate laterally such that the first side of the at least one first substrate and the first side of the at least one second substrate face away from the baseplate in the same direction; and
encasing the at least one first substrate and the at least one second substrate in a common frame, the common frame being a monobloc part,
wherein the one or more first semiconductor dies and the at least one first substrate provide a higher power part of the power electronics module, and the one or more second semiconductor dies and the at least one second substrate provide a lower power part of the power electronics module.
