  • Abstract
    We have found an effective dry cleaning technique using SiCl4 as a cleaning gas. Now, for the first time, surface Fe contaminants can be removed from an SiO2 surface using SiCl 4. A Cl2+SiCl4 combination allows dry cleaning of a Si surface at a lower temperature than the conventional UV/Cl2 method. Use of this Cl2+SiCl4 mixture gave good surface flatness and surface constitution for both Si and SiO2 surfaces
