1. Introduction. The conventional way of pulling mono-crystalline Czochralski (CZ) silicon ingots for electronic applications usually results in wafers, which contain voids in concentrations between 10 6 and 10 7 cm −3. These ingots are pulled rapidly in the vacancy-rich regime. During cooling the vacancies supersaturate and agglomerate.
