    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.

One of the first and second semiconductor zones constitute drift zones and a diffusion coefficient of the second dopant species is at least twice as large as the diffusion coefficient of the first dopant species. A concentration profile of the first dopant species along a vertical direction perpendicular to the surface of the semiconductor body includes at least two maxima.
