Classification: CPC B  H  G | IPC B  H

Claim 0:
1. A flattening apparatus comprising:
a mold holding unit configured to suck and hold a mold, the mold including a flat portion;
a substrate holding unit configured to hold a substrate;
an exposure unit configured to irradiate a light curing composition supplied onto the substrate with light at least via the mold to cure the composition, the composition being irradiated with the light and cured in a state where the flat portion of the mold is in contact with the composition on the substrate;
a gas suction unit configured to suck gas from a spatial region between the mold and the mold holding unit;
a gas supply unit configured to supply the gas to the spatial region; and
a control unit configured to control the gas suction unit and the gas supply unit to perform temperature adjustment processing for supplying the gas to the spatial region in a state where the mold is sucked and held onto the mold holding unit,
wherein the control unit is configured to perform control such that 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.
