A semiconductor component includes a semiconductor body of a first conductivity type which accommodates a space charge region. Semiconductor regions of a second conductivity type are disposed in at least one plane extending essentially perpendicularly to a connecting line extending between two electrodes. A cell array is disposed under one of the electrodes in the semiconductor body. At least some of the semiconductor regions of the second conductivity type are connected to the cell array via filiform semiconductor zones of the second conductivity type in order to expedite switching processes. A method for fabricating such a semiconductor component is also provided.
