Abstract: A semiconductor component and a method for manufacturing such a semiconductor component which has a resistance behavior which depends heavily on the temperature. This resistance behavior is obtained by a special multi-layer structure of the semiconductor component, one layer being designed in such a way that, for example, multiple p-doped regions are present in an n-doped region, said regions being short-circuited on one side via a metal-plated layer. For example, the semiconductor component may be used for reducing current peaks, by being integrated into a conductor. In the cold state, the semiconductor component has a high resistance which becomes significantly lower when the semiconductor component is heated as a result of the flowing current.
