Czochralski Crystal Puller from Canada
A specialized mixing and stirring machine used in semiconductor manufacturing to grow monocrystalline silicon boules via the Czochralski method, where a seed crystal is dipped into molten silicon and slowly pulled while rotating to form pure crystals. It falls under HTS 8479.82.0040 as a stirring machine for high-precision material processing in wafer production. The continuous stirring of the melt ensures uniform crystal growth essential for semiconductor wafers.
