Abstract
The present invention provides a method of removing a foreign particle on a first member, comprising: supplying a composition on the first member; pressing a second member against the composition supplied on the first member; curing the composition on the first member after the pressing; and separating the second member together with the composition from the first member, after the curing, wherein in the supplying, a supply amount of the composition to be supplied on the first member is controlled based on a cure shrinkage rate of the composition in the curing and an estimated size of a foreign particle being presumably adhered on the first member, such that a thickness of a portion of the composition cured in the curing, which exists between the second member and the first member, becomes larger than the estimated size.
