An aqueous solution of ammonia, tetramethylammonium hydroxide and sodium hydroxide, etc. has been used as a cleaning liquid and an etching liquid of a semiconductor substrate and a glass substrate. However, the metal impurities in the alkali components are adsorbed onto the substrate surface during treatment, so that a process for removing the adsorbed metal impurities is necessary as the next process. In addition, in the case of the cleaning liquid, though it is effective in the removal of fine particles, the metal impurities cannot be cleaned, so that it is necessary to carry out acid cleaning, which makes the process complicated. According to the present invention, the alkaline aqueous solution for treating a substrate wherein an alkali component and a specific chelating agent are combined prevents adsorption of metal impurities onto the substrate, and further cleans and removes the metals adhered to the substrate. If necessary, it is also possible to add a metal anticorrosive and a surfactant to suppress corrosion of the metal materials, or enhance affinity to the substrate and ability for removing fine particles.
