The invention relates to a high voltage resistant edge structure in the edge region of a semiconductor component which has floating guard rings of the first conductivity type and inter-ring zones of the second conductivity type which are arranged between the floating guard rings, wherein the conductivities and / or the inter-ring zones are set such that their charge carriers are totally depleted when blocking voltage is applied.
