Abstract
Semiconductor components containing at least one junction and at least one weakly N- or P-conducting zone containing from 10.sup.13 to 2.5 .times. 10.sup.14 doping atoms/cm.sup.3 are prepared by diffusing dopant atoms at elevated temperatures into appropriate zones of a semiconductor crystal from a nickel film containing the dopant deposited on the surface of the crystal and then cooling the in-diffused semiconductor crystal to room temperature at a rate sufficient such that the specific resistance of the weakly doped zone is not changed by the nickel atoms which diffuse into the semiconductor crystal along with the doping atom.
