Czochralski Crystal Puller from Japan
A Czochralski crystal puller is used to produce extremely pure monocrystalline semiconductor boules from which silicon wafers are sliced, fitting under HTS 8412.90.90.85 as a part of semiconductor manufacturing equipment powered by reaction engines or motors. It employs the Czochralski method for growing semiconductor crystals like silicon and gallium arsenide.
