  • Patent number: 11505493
    Abstract: Disclosed is a method of treating the surface of a quartz member. The method can remove a masking material generated by a chemical reaction between the quartz member and an etching solution, thereby completely removing scratches on the surface of the quartz member without interrupting the treatment process unlike existing technologies. The method also embosses the surface of the quartz member, thereby increasing the frictional resistance and surface roughness of the surface of the quartz member depending on the shape or density of protrusions on the surface. In addition, the method prevents deposits on the surface of the quartz member from peeling off.
