Abstract:
1. A method for fabricating a semiconductor element in a substrate, the method comprising: implanting first implantation ions into the substrate, whereby micro-cavities are produced in a first partial region of the substrate; implanting pre-amorphization ions into the substrate, whereby a second partial region of the substrate is at least partly amorphized, and whereby crystal defects are produced in the substrate; implanting second implantation ions into the second partial region of the substrate, wherein the second implantation ions comprise reactive ions, wherein the reactive ions are selected from the group consisting of Cl+ ions and N+ ions; heating the substrate, such that at least some of the crystal defects are eliminated using the second implantation ions; and implanting dopant atoms into the second partial region of the substrate, wherein the semiconductor element is formed using the dopant atoms.
