Abstract: PURPOSE: A fabricating method of a thin film through a sol-gel technique is provided to prevent undesirable phenomena such as fracture, crack, or roughness of the thin film without employing a drying additive. CONSTITUTION: A method for fabricating a thin film through a sol-gel technique includes a step of coating a sol solution in which a film material is dissolved on a substrate or a preformed thin film, and a step of forming the thin film of gel state by drying the coated sol solution. In particular, the sol solution does not employ a drying control chemical additive. However, the sol solution has a good property of preventing fracture, crack, or roughness of the thin film. Such a property of the sol solution is obtained by controlling surface tension thereof. Surface tension of the sol solution is controlled by changing the mixture ratio between solvent and distilled water. Preferably, the sol solution may have surface tension of less than 35 dyne/cm by mixing solvent of two mol or more per one mol distilled water.
