    摘要: Transistor cells (2) of a power transistor component are in each case provided with a gate conductor structure that forms a gate electrode (52) in sections and is connected via a gate cell terminal (43) to a gate wiring line (81) led to a gate terminal (44) of the power transistor component (1). The gate conductor structure (5) has a desired fusible section (51) with an increased resistance, which is arranged within a cavity. The resistance of the desired fusible section (51) can be set in such a way that, in the event of a current loading of the magnitude of a value that is typical of a defective gate dielectric (41), the gate conductor section (5) is interrupted in the desired fusible section (51) and the gate electrode (52) is disconnected from the gate wiring line (81). The power transistor component can be produced with high yield and has a smaller number of failures during application operation.

    摘要: A semiconductor device in one embodiment has a first connection region, a second connection region and a semiconductor volume arranged between the first and second connection regions. Provision is made, within the semiconductor volume, in the vicinity of the second connection region, of a field stop zone for spatially delimiting a space charge zone that can be formed in the semiconductor volume, and of an anode region adjoining the first connection region. The dopant concentration profile within the semiconductor volume is configured such that the integral of the ionized dopant charge over the semiconductor volume, proceeding from an interface of the anode region which faces the second connection region, in the direction of the second connection region, reaches a quantity of charge corresponding to the breakdown charge of the semiconductor device only near the interface of the field stop zone which faces the second connection region.
