A semiconductor power component and a method for producing a semiconductor power component, in particular a vertical NPT-IGBT for ignition applications with a breakdown voltage of less than approx. 1000 V. The semiconductor power component includes a wafer substrate of a first conductive type including a rear-side emitter region of a second conductive type and a front-side drift region of the first conductive type; a rear-side anode contact which is connected to the emitter region and extends partially to the front-side surface; a front-side MOS control structure; and a front-side cathode contact which is connected to a front-side source region and a body region of the front-side MOS control structure. The thickness of the drift region is much larger than the width of the space charge region at a defined breakdown voltage; and the thickness of the rear-side emitter region is greater than 5 μm.

The present invention relates to a circuit configuration for protecting against polarity reversal of a DMOS transistor. A charge carrier zone (30) is provided, situated in the drift zone (14) of DMOS transistor (10), made up of individual partial charge carrier zones (32) situated at a distance from one another and connected to one another in a conducting manner, the charge carrier zone (30) having an opposite charge carrier doping from that of the drift zone (14), and being able to be acted upon by a potential that is negative with respect to a potential present at a drain terminal (24) of the DMOS transistor (10), so that a short-circuit current is prevented.

An inverter for an electric machine is specified that includes a plurality of switching elements, in particular six, which are positioned in a bridge circuit and produce a connection between the electric machine and a battery. The switching elements built into the low-side branch of the inverter are ones that are conductive without a control voltage present, i.e., normally-on switching elements. That ensures that if the supply voltage is absent and the electric machine is rotating the windings of the electric machine are short circuited and no overvoltages are able to occur. In normal operation the inverter is operated like a conventional inverter, by clocked actuation, but with reversed actuation of the control electrodes, i.e., with control voltage for non-conductive time phases and without control voltage in conductive phases.

The invention concerns a monolithically integrated semiconductor component, having a first charge carrier region of a first charge carrier doping; at least two second charge carrier regions with opposite charge carrier doping, patterned within the first charge carrier region at a spacing from one another, and third charge carrier regions, with the first charge carrier doping, patterned within the second charge carrier regions, a PN transition being short-circuited between the second charge carrier regions and the third charge carrier regions via a contacting area (source connection), the first charge carrier region being equipped with a contact (drain connection), and the second charge carrier regions being invertable by means of a contacting area in the region between the first charge carrier region and the third charge carrier region; and having at least one Schottky diode connected in parallel with the charge carrier region and the charge carrier region. Provision is made for the first charge carrier region to have a further contacting area, this contacting area being additionally doped near the surface, depending on the doping concentration of the first region, with a further near-surface charge carrier region of higher concentration, so that an ohmic contact is created and is connected to the anode connection of the at least one Schottky diode.
