Abstract
A minute convexo-concave pattern forming method includes: transferring a minute convexo-concave pattern of a mold to a resist layer of a transfer substrate where a resist layer is formed on a substrate and curing the transferred minute convexo-concave pattern; and after curing the transferred minute convexo-concave pattern, peeling the transfer substrate and the mold, the peeling step including: pressurizing a substrate back surface side of the transfer substrate with a peripheral part of the transfer substrate being fixed to bend the transfer substrate in a curved shape and starting peeling of the transfer substrate and the mold with a bending of the transfer substrate; and peeling a part of the minute convexo-concave pattern of the transfer substrate not peeled in the first peeling step by gradually decreasing a pressure for a pressurization so as to undo the bending of the transfer substrate.
