Abstract:
PURPOSE: A thin film patterning method and a manufacturing method of a semiconductor device using the same are provided to simplify a manufacturing process by patterning a thin film of a simple process without a separate sensitive film. CONSTITUTION: A precursor solution including a precursor of metal oxide is prepared. A thin film (200) is formed by spreading the precursor solution on a substrate (100). The thin film is softly dried. The thin film is exposed to the light by using a photomask in an ozone atmosphere. The part which is not exposed to the light is developed. A patterned metal oxide thin film is formed by hardly drying the developed thin film.
