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.

摘要： A semiconductor body of a semiconductor device includes a doped layer of a first conductivity type and one or more doped zones of a second conductivity type. The one or more doped zones are formed between the doped layer and the first surface of a semiconductor body. Trench structures extend from one of the first and the second opposing surface into the semiconductor body. The trench structures are arranged between portions of the semiconductor body which are electrically connected to each other. The trench structures may be arranged for mitigating mechanical stress, locally controlling charge carrier mobility, locally controlling a charge carrier recombination rate and/or shaping buried diffusion zones.
