Abstract
Crystal pulling systems for growing monocrystalline ingots from a melt of semiconductor or solar-grade material are described. The crystal pulling systems include seed chuck assemblies designed to reduce formation of deposits on components of the crystal pulling systems by reducing and inhibiting the formation of gas flow recirculation cells within the crystal pulling systems.
