Abstract
In order to produce silicon wafers, liquid ultra-pure silicon is solidified on a silicon monocrystalline seed arranged in the bottom area of a crucible and having a seed surface comprising a {110}-crystal orientation and an edge surface having a {100}-crystal orientation starting from the bottom of the crucible, thus forming a silicon block on the seed surface of the silicon monocrystalline seed which largely takes over the {110}-crystal orientation. Subsequently, the silicon block is divided into wafers with a wafer surface having a {100}-crystal orientation.
