Czochralski Crystal Puller Nozzle Assembly from Mexico
This nozzle assembly is a critical part of Czochralski crystal pullers used in semiconductor wafer manufacturing to project inert gas jets for controlled crystal growth. It falls under HTS 8424.90.90.40 as a component of steam and similar jet projecting machines employed in high-purity monocrystalline silicon boule production. The precise jet projection ensures minimal contamination during the pulling process.
