Patent ID: 8304015

Claim:
A method of forming a resin film on a substrate by depositing droplets of resin liquid by an inkjet method, comprising: a first resin liquid arrangement step of arranging a plurality of droplets of a first resin liquid separately from each other on a substrate in such a manner that the droplets do not make contact with each other; a first resin liquid curing step of curing at least a surface of each of the droplets of the first resin liquid arranged on the substrate; a second resin liquid arrangement step of arranging a plurality of droplets of a second resin liquid at substantially central positions between the droplets of the first resin liquid on the substrate, after the at least the surface of each of the droplets of the first resin liquid is cured; a second resin liquid curing step of curing the droplets of the second resin liquid arranged on the substrate, a third resin liquid arrangement step of separately arranging at least two droplets of a third resin liquid of smaller volume than the droplets of the first resin liquid so as not to make contact with the droplets of the first resin liquid at respective edge portions, in a direction perpendicular to a direction of arrangement of the droplets of the first resin liquid, of a region corresponding to a gap between the droplets of the first resin liquid on the substrate; and a third resin liquid curing step of curing at least a surface of each of the droplets of the third resin liquid arranged on the substrate, wherein the second resin liquid arrangement step is carried out after the at least the surface of each of the droplets of the third resin liquid is cured.
