Abstract:
The present invention relates to a method for manufacturing a multilayer thin film using a sol-gel process. The present invention includes a step of coating a first thin film on a rotating substrate; a step of measuring a contact angle for the hydrophobic analysis of the surface of the first thin film; a step of coating a second thin film on the first thin film; and a step of performing a thermal process for the crystallization of a thin film material. The first thin film and the second thin film are successively laminated, and then a thermal process is performed to form a multilayer thin film. According to the present invention, the residual organic material of a sol-gel process is analyzed according to the condition of a thermal process, thereby effectively performing a thermal process for manufacturing a multilayer thin film without having to apply existing additional processes such as an ultraviolet ray or plasma process.
