Czochralski Crystal Puller from Japan
A machine used to produce monocrystalline silicon boules by slowly pulling a seed crystal from molten silicon in the Czochralski method. It is essential for semiconductor wafer manufacturing as it creates the pure crystal ingots from which wafers are sliced. Classified under HTS 8479.79.00.00 as a machine having individual function not specified elsewhere for semiconductor material growth.
