Abstract: PURPOSE: A method of patterning an indium tin oxide layer on a plastic thin film and a rotary coater used for the method are provided to coat photoresist in uniform thickness and prevent undercut generated in the event of wet etching. CONSTITUTION: An ITO layer(11) is formed on a plastic substrate(10), and photoresist is coated on the ITO layer. Heat treatment is performed in order to remove a solvent contained in the coated photoresist. Ultraviolet rays are irradiated on a portion of the ITO layer, which is etched, using a patterned mask. The exposed portion of the photoresist is developed. Heat treatment is carried out to eliminate moisture and solvent left in the photoresist. The ITO layer is dipped in an ITO etchant using the patterned photoresist as a mask to wet-etch the ITO layer. The photoresist used as the mask is stripped.
