摘要: A method for producing large-area power semiconductor components, wherein at least two irradiation processes (neutron irridiation, ion implantation electron, .gamma.or proton irradiation) are used to produce the basic doping, to introduce deep pn junctions and to introduce recombination centers. It is precisely for the critical process steps (p-base, n-type stop layer) that the improved homogeneity of the layers signifies a higher yield and improved limit data for the finished components.
