Abstract:
1. A pattern formation method comprising: applying a plurality of resist droplets for imprinting to a substrate discretely in space, the resist droplets including a first resin component that is nonvolatile, a second resin component that is volatile, and a coupling reaction initiator that promotes curing of the first resin component; causing the second resin component in the plurality of resist droplets applied to the substrate discretely to evaporate, thereby reducing the resist droplets in volume and keeping the resist droplets discrete; imprinting a pattern surface of a template onto, in the order of resist drop application, a shot of the resist droplets, the resist droplets which are reduced in volume due to the second resin component that has evaporated and are discrete, the resist droplets being transformed to a resist film by the imprinting; curing the resist film while keeping the pattern surface of the template imprinted onto the resist film; and separating the template from the resist film after the resist film has been cured, wherein during the imprinting a pattern surface of a template onto the resist droplets reduced in volume in the shot, resist droplets for imprinting are applied onto the substrate discretely in space in another shot.
