    Abstract: In order to produce a power semiconductor for operation at high blocking voltages, there is produced on a lightly doped layer having a doping of a first charge carrier type a medium-doped layer of the same charge carrier type. A highly doped layer is produced at that side of the medium-doped layer which is remote from the lightly doped layer, of which highly doped layer a part with high doping that remains in the finished semiconductor forms a second stop layer, wherein the doping of the highly doped layer is higher than the doping of the medium-doped layer. An electrode is subsequently indiffused into the highly doped layer. The part with low doping that remains in the finished semiconductor forms the drift layer and the remaining medium-doped part forms the first stop layer.

    Abstract: A method for producing a semiconductor device such as a RC-IGBT or a BIGT having a patterned surface wherein partial regions doped with dopants of a first conductivity type and regions doped with dopants of a second conductivity type are on a same side of a semiconductor substrate is proposed. An exemplary method includes: (a) implanting dopants of the first conductivity type and implanting dopants of the second conductivity type into the surface to be patterned; (b) locally activating dopants of the first conductivity type by locally heating the partial region of the surface to be patterned to a first temperature (e.g., between 900 and 1000° C.) using a laser beam similar to those used in laser annealing; and (c) activating the dopants of the second conductivity type by heating the substrate to a second temperature lower than the first temperature (e.g., to a temperature below 600° C.). Boron is an exemplary dopant of the first conductivity type, and phosphorous is an exemplary dopant of the second conductivity type. Boron can be activated in the regions irradiated only with the laser beam, whereas phosphorus may be activated in a low temperature sintering step on the entire surface.
