Method and apparatus for pulling a monocrystal

摘要

A method and an apparatus for pulling a silicon monocrystal from a melt includes the pulling of a conical portion in each case at the beginning and at the end of the monocrystal and the pulling of a cylindrical portion between the conical portions. In this method, the surface of the conical portion at the beginning of the monocrystal is shielded by a shielding means spaced apart from the monocrystal.
