Ingot lifting device equipped with a dopant dispenser for adding multiple dopant batches.

Abstract

An ingot pulling apparatus for producing doped single-crystal silicon ingots is disclosed. The ingot pulling apparatus includes a dopant feeder comprising a first dopant receptacle for holding a first dopant batch and a second dopant receptacle for holding a second dopant batch. A rotating mechanism rotates the first dopant receptacle to release the first dopant batch into the crucible and rotates the second dopant receptacle to release the second dopant batch into the crucible.
