Title: Method for evaluating analyzing cleanliness of clean room ambience
Inventor: SHIROMIZU YOSHIMI
IPC: G01N30/00
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To evaluate and analyze metals, organic substances, inorganic components such as ammonia, etc., in a clean room ambience by providing a process of selectively catching to a semiconductor substrate of a surface state corresponding to each kind to be caught. SOLUTION: A semiconductor substrate is thermally oxidized to assume polarities on a surface, thereby chemically adsorbing organic impurities in a clean room ambience. An acid treatment to the semiconductor substrate enables metallic components to be selectively caught and is effective to catch ammonia and lower amine. When the semiconductor substrate is alkalized to be charged positive, the substrate is ion bonded with hydrochloric acid ions, nitric acid ions, sulfuric acid ions, etc., thus enabling selective adsorption. Moreover, when the semiconductor substrate is treated with hydrofluoric acid to terminate the surface with hydrogen and fluorine, floating boric acid of boron components are decomposed, so that boron is selectively adsorbed to the surface.  Impurities in the clean room ambience can be selectively efficiently caught by the four kinds of the semiconductor substrate surfaces.
