Float Zone Crystal Grower for Gallium Arsenide Wafers from Japan

Machine employing float zone method to produce high-purity monocrystalline semiconductor boules from polycrystalline rods, essential for slicing into GaAs wafers. It precisely controls melting zones for defect-free crystals used in optoelectronics. Falls under HTS 8465.96.0040 as a paring/splitting machine for hard materials in semiconductor prep analogous to woodworking tools.
