Abstract:
1. A method of performing pattern transfer, the method comprising: applying liquid to a substrate, while performing relative movement of the substrate and a liquid ejection head having a plurality of nozzles, by performing ejection and deposition of a plurality of droplets of the liquid from the nozzles onto the substrate in a state where a shape of each of the droplets upon the deposition is not a single circular shape and each of the droplets does not combine with adjacent another of the droplets on the substrate; and curing the liquid that has been applied to the substrate in the applying step while pressing a pattern forming surface of a stamper having a prescribed projection-recess pattern against the liquid, wherein each of the droplets upon the ejection from the nozzles has a substantially columnar shape and satisfies: where V is a volume of each of the droplets, l is a length of the substantially columnar shape of each of the droplets, U d is a speed of each of the droplets upon the ejection, U k is a speed of the relative movement of the substrate and the liquid ejection head, and θ is an angle of contact between each of the droplets and the substrate.
