Abstract
A semiconductor component comprises a pn junction in which both the p-conducting and the n-conducting layers of the pn junction are doped silicon carbide layers and the edge of at least one of the conducting layers of the pn junction exhibits a stepwise or uniformly decreasing total charge or effective surface charge density from the initial value at the defined working junction to a zero or almost zero total charge at the outermost edge of the junction following a radial direction from the central part of the junction towards its outermost edge.
