Abstract:
A power semiconductor component, comprising:an n-doped silicon layer; a first main area and a second main area; a plurality of doped layers introduced into said n-doped silicon layer between said first main area and said second main area; said doped layers, as seen from said second main area, including a p-doped anode zone and an n-doped stop layer adjoining said p-doped anode zone; said n-doped silicon layer having a first dopant concentration, said n-doped stop layer having a second dopant concentration higher than said first dopant concentration, said n-doped stop layer adjoining and completely covering said n-doped silicon layer; said n-doped stop layer being doped with at least one dopant having at least one donor level between a valence band edge of silicon and a conduction band edge of silicon and the at least one donor level being more than 200 meV away from the conduction band edge of silicon, to form said n-doped stop layer non-epitaxially and without lengthy deep diffusion; a cathode assigned to said first main area and formed by a first metallization layer; and an anode formed by a second metallization layer covering said second main area.
