The Czochralski Process (CZ) and Float-zone refining of silicon necessitate an inert argon atmosphere to minimize impurities. The purity of the argon directly influences the density of impurities that can diffuse into the crystal structure. Additionally, the vacuum level prior to introducing argon is crucial; a higher vacuum enhances the effectiveness of the inert atmosphere. Maintaining optimal pressure is also essential, as it helps prevent the separation of volatile components from the melt, thereby preserving stoichiometry.
