ABSTRACT:
A process for reducing the load on a seed crystal during the pulling of a single crystal uses a pulling device. An adhesive bond is made between a conical section at the start of the single crystal and a retaining body. The load on the seed crystal is reduced by creating a tensile stress between the retaining body and the pulling device.
