A method of forming a thin-film including a capability to remove contaminants from the formed thin-film and/or a substrate on which the thin-film is formed using alcohol. The method includes allowing a substrate holder to support a substract. A first mixture is produced by mixing a condensation polymer containing an element of metal oxide compound and alcohol. Then second mixture is produced by mixing supercritical fluid or liquid carbon dioxide and the first mixture. A thin film is formed by applying the second mixture on a surface of the substrate. After forming the thin-film, the substrate is cleaned by applying alcohol to upper and lower surfaces, preferably the whole upper and lower surfaces, of the substract. The thin-film is crystallized by heating, and the crystallizing may include applying oxygen in a crystallizing chamber. Soft X-rays may be applied to the substrate, during the forming of the thin-film on the surface of the substrate.
