Patent Document 5 describes that this positive photosensitive resin composition is suitable for use as an interlayer insulating film in a liquid crystal display or an EL display, a light shielding material corresponding to an inkjet method, or a partition material.
- Patent Documents 4 and 5 when a pattern film is formed on a substrate by photolithography, the substrate surface, which is a concave portion of the pattern film, is contaminated with an organic substance, and when formed by an imprint method, the pattern film Since the recesses of the pattern film become water-repellent due to defects such as film residue in the recesses, hydrophilic treatment is performed on the substrate with the pattern film using hydrophilic ink to make the recesses of the pattern film hydrophilic. It is described. When the hydrophilization treatment is performed, in the ink jet, the ink can be satisfactorily dropped onto the substrate with the pattern film without the concave portions of the pattern film repelling the ink.
- Patent Document 4 a substrate with a pattern film is brought into contact with oxygen plasma gas and fluorine plasma gas so that the substrate surface, which is a concave portion of the pattern film, has hydrophilicity, and the bank of the convex portion has water repellency. Is described.
- a substrate with a pattern film is obtained that maintains high liquid repellency on the surface of the pattern film that is a bank even after UV ozone cleaning in the hydrophilic treatment. It is said that it is possible.
- a method of manufacturing a substrate with a pattern film that solves the above problem is provided.
- the present disclosure also provides a novel fluorine-containing copolymer contained in the pattern film.
- the present inventors have conducted intensive studies. As a result, when UV ozone cleaning or oxygen plasma cleaning is performed on a substrate with a pattern film containing a specific fluorine-containing copolymer, the pattern film is repelled. It was found that the liquid property is once lowered, but then the liquid repellency can be obtained by heating (the liquid repellency is restored).
- the pattern film containing a specific fluorine-containing copolymer showed a decrease in liquid repellency with respect to water and anisole used as an ink solvent in an inkjet method after UV ozone cleaning or oxygen plasma cleaning, By heating the pattern film, the lowered liquid repellency was restored for both water and anisole (see Tables 2 and 3 in [Examples] of this specification).
- the pattern film containing a specific fluorine-containing copolymer showed a decrease in liquid repellency with respect to propylene glycol monomethyl ether acetate (PGMEA) and xylene after UV ozone cleaning or oxygen plasma cleaning.

- a special fluorine-containing copolymer capable of suppressing the cleavage of the polymer main chain.
- UV ozone cleaning means that the substrate with the pattern film is irradiated with ultraviolet rays to decompose the organic contaminants attached to the pattern film and the concave portions of the substrate with the pattern film, and at the same time separated from the ozone generated by the ultraviolet irradiation.
- Active oxygen is a method that chemically bonds with organic pollutants, decomposes them into volatile substances such as carbon dioxide and water, and removes organic pollutants.
- a low-pressure mercury lamp is usually used for the ultraviolet irradiation device.
- oxygen plasma cleaning is a method in which an organic pollutant that adheres to the surface of a substrate with a pattern film is formed by applying high voltage to a gas containing oxygen molecules to dissociate the oxygen molecules, and adhering to the surface of the substrate with the pattern film.
