Czochralski Crystal Puller from Japan
A specialized machine used in semiconductor manufacturing to grow monocrystalline silicon boules by slowly pulling a seed crystal from molten silicon using the Czochralski method. It falls under HTS 8479.82.00 as a mixing or stirring machine due to the precise stirring and homogenization of the melt to ensure crystal purity and uniformity.
