Czochralski Crystal Puller for Silicon Wafer Production from Mexico
A specialized machine tool that uses the Czochralski method to grow monocrystalline silicon boules by pulling a seed crystal from molten silicon. The boule is then sliced into wafers for semiconductor fabrication. Classified under HTS 8465.96.0040 as a splitting, slicing, or paring machine for woodworking due to its precision slicing capabilities on hard materials akin to wood processing.
