Title: Cleaning method for surface
Inventor: TANAKA MASATO
IPC: B08B7/00
Filed: 1986-07-28
Abstract: PURPOSE:To decompose and remove inorganic contaminants adhering to the surface of a wafer by irradiating the wafer with ultraviolet rays for a predetermined time before cleaning or during the cleaning. CONSTITUTION:A surface treating solution is supplied to the surface of a wafer W, the surface is treated as predetermined, and ultraviolet rays are then emitted to inorganic ions of the solution coupled with the surface of the wafer W. Thus, the energy of the emitted ultraviolet rays is absorbed to the ions to become an active state, and the bond between the molecules between the ions and the wafer W can be cut as the absorbing effect. When the surface of the wafer W of this state is cleaned with cleaning water, such as pure water, the separated ions are removed from the surface of the wafer W. When the ultraviolet rays are emitted to it during the cleansing step, the pure water on the wafer is photodecomposed to hydroxide ions or hydrogen ions and becomes capable of combining with the activated ions to readily separate the ions from the surface of the wafer W.
