Abstract:
A method for producing a semiconductor component in which at least one doped region is introduced into a semiconductor wafer, comprising the steps of:applying a solid glass layer both on the front side of the semiconductor wafer and on the back side of the semiconductor wafer, a doping type of the dopant on the back side being opposite compared to the doping type of the dopant on the front side; heating the semiconductor wafer to a high temperature of at least 1200 degrees centigrade while the glass layer is applied so that the dopant from the solid glass layer penetrates into the semiconductor wafer to produce the at least one doped region; applying a neutral glass layer on the solid glass layers prior to heating the semiconductor wafer; removing the neutral glass layers together with the solid glass layers after heating the semiconductor wafer; and providing the dopant at a dosage of at least 1017/cm2 in the at least one doped region; wherein the step of applying the solid glass layer is performed in accordance with a chemical vapor deposition at atmospheric pressure.
