Abstract
A film formation device for forming a film of a composition on the substrate by irradiating the composition on the substrate with light, includes an optical modulation unit for forming a distribution of an integrated light amount of the light on the substrate, and a control unit for controlling the optical modulation unit, in which the control unit controls the distribution of the integrated light amount of the optical modulation unit on the basis of residual film ratio characteristics of the composition and at least one of a curved shape of an imaging plane of an original template used in a subsequent process and a surface shape of a base film formed on the substrate.
