Abstract
The present invention includes forming a hydrophobic thin film on a substrate, removing a portion of the first hydrophobic thin film to form a first hydrophilic region, coating a first organic solution on the substrate and selectively wetting the first hydrophilic region, drying the first organic solution to form a first organic thin film pattern in the first hydrophilic region, forming a second hydrophobic thin film on the first organic thin film pattern, coating a second organic solution and selectively wetting the second organic solution, and drying the second organic solution to form a second organic thin film pattern.
