Technical Examples
A method for eliminating eruptions, impurities, and/or damage in a crystal lattice by selectively etching silicon elements of surface-plated and sawn-out parts of a silicon wafer. At least areas of the silicon elements are brought into contact with a gaseous etching medium that etches silicon selectively in a chemical reaction, and gaseous reaction products are produced during etching. An interhalogen or fluorine-noble gas compound that is in a gaseous state or was converted to the gaseous phase may be used as the etching medium. The method is believed to be suitable for producing power diodes sawn from a wafer or for overetching fully mounted individual diodes.
