A MOS field plate trench transistor device is disclosed. In one embodiment, in order to obtain a lowest possible on resistance, in the case of a MOS field plate trench transistor device having a body contact hole, it is proposed to form the avalanche breakdown region preferably in an end region of a provided trench structure by virtue of the fact that a mesa region with the body contact region in the semiconductor region as intermediate region in a direction running perpendicular to the first direction and with respect to an adjacent MOS transistor device has a width DMesa, the value of which corresponds to the value of the width DTrench of the trench structure in this direction or exceeds said value and does not go beyond 1.5 times said value, so that the following holds true: DTrench≦DMesa≦1.5·DTrench. As an alternative, the width DMesa is chosen such that the body contact hole precisely still has space, but the breakdown region is in any event shifted into the end region.

A method for fabricating a semiconductor power component is disclosed. In one embodiment, the method for fabricating a semiconductor power component includes formation of a semiconductor structure in/on a substrate, a semiconductor region serving as a stop layer being formed at the level of a target thickness of the semiconductor power component through the semiconductor structure in the semiconductor structure or in the substrate, the doping concentration of said semiconductor region being increased/reduced with respect to that of the substrate, and/or the doping type of said semiconductor region being inverted with respect to that of the substrate. At least one part of the substrate is thinned to the target thickness using an etchant whose etching rate is dependent on the concentration and/or the type of the doping, the etchant being chosen such that the thinning process is stopped or slowed down by the semiconductor region serving as a stop layer.
