Abstract:
A method for producing a power semiconductor module arrangement includes arranging two or more individual semiconductor devices on a base layer, each semiconductor device including a lead frame, a semiconductor body arranged on the lead frame, and a molding material enclosing the semiconductor body and at least part of the lead frame, arranging a frame on the base layer such that the frame surrounds the two or more individual semiconductor devices, and filling a first material into a capacity formed by the base layer and the frame, and hardening the first material to form a casting compound that at least partly fills the capacity, thereby at least partly encloses the two or more individual semiconductor devices.
Abstract:
A semiconductor arrangement includes upper and lower contact plates and basic chip assemblies. Each chip assembly has a semiconductor chip having a semiconductor body with upper and lower spaced apart sides. An individual upper main electrode and an individual control electrode are arranged on the upper side. The chip assemblies have either respectively a separate lower main electrode arranged on the lower side of the semiconductor chip of the corresponding basic chip assembly, or a common lower main electrode, which for each of the chip assemblies is arranged on the lower side of the semiconductor body of that chip assembly. An electrical current between the individual upper main electrode and the individual or common lower main electrode is controllable by its control electrode. The chip assemblies are connected to one another with a material bonded connection by a dielectric embedding compound, forming a solid assembly.

Abstract:
A semiconductor device includes a drift zone in a semiconductor body. A charge-carrier transfer region forms a pn junction with the drift zone in the semiconductor body. A control structure electrically connects a recombination region to the drift zone during a desaturation cycle and disconnects the recombination region from the drift zone outside the desaturation cycle. During the desaturation cycle the recombination region reduces a charge carrier plasma in the drift zone and reduces reverse recovery losses without adversely affecting blocking characteristics.

Abstract:
A method for driving a controllable power semiconductor switch, having a first input terminal and first and second output terminals coupled to a voltage supply and a load, the first and second output terminals providing an output of the power semiconductor switch, includes adjusting a gradient of switch-off edges of an output current and an output voltage of the power semiconductor switch by a voltage source arrangement coupled to the input terminal. A gradient of switch-on edges of an output current and an output voltage is adjusted by a controllable current source arrangement that is coupled to the input terminal and generates a gate drive current. The profile of the gate drive current from one switching operation to a subsequent switching operation, beginning at a rise in the output current and ending at a decrease in the output voltage, is varied at most within a predefined tolerance band.
