Claim 11:
12. A flattening method of a flattening apparatus including a mold holding unit configured to suck and hold a mold including a flat portion and a substrate holding unit configured to hold a substrate, the flattening apparatus being configured to irradiate a light curing composition supplied onto the substrate with light to cure the composition in a state where the flat portion of the mold is in contact with the composition on the substrate, the flattening method comprising:
adjusting temperature of the mold by supplying gas to a spatial region between the mold and the mold holding unit in a state where the mold is sucked and held onto the mold holding unit;
bringing the mold into contact with the composition on the substrate; and
irradiating the composition on the substrate with the light at least via the mold to cure the composition,
the adjusting, the bringing, and the irradiating being performed in this order,
wherein processing of irradiating the composition with the light to cure the composition in a state where the mold held on the mold holding unit is brought into contact with the composition on the substrate is executed with the mold separated from the mold holding unit.
