Czochralski Crystal Puller from Canada
A machine used to produce monocrystalline silicon boules by slowly pulling a seed crystal from molten silicon in a crucible, employing the Czochralski method. It falls under HTS 8445.90.00.00 as other machinery for preparing fibers, analogous to preparing semiconductor crystal 'fibers' from raw material for subsequent wafer processing. This equipment is essential for semiconductor wafer manufacturing.
