  • Patent number: 11353789
    Abstract: An imprint method using a mold and/or a transfer substrate having a mesa structure includes a resin supply step, a contact step, a curing step, and a mold release step. In the resin supply step, a balance layer is formed by supplying a molded resin also to an area outside of a pattern formation area of the transfer substrate in which a pattern structure is to be formed.

  • Patent number: 10960598
    Abstract: Provided are: an imprinting method which suppresses volatilization of a photocurable resin applied on a transfer-receiving substrate by an inkjet method, satisfactorily maintains the wet-spreading property of the resin at the time of transfer, maintains cleanness of the environment for transfer, and can fill the environment for transfer with a particular gas appropriate for transfer; and an imprinting apparatus. Disclosed is an imprinting method of using a template having a concavo-convex pattern formed thereon, and transferring the pattern of the template by imprinting to a photocurable resin on a transfer-receiving substrate, characterized in that, in a space where the template and the photocurable resin are brought into contact, clean air is sent to the space through an air blowing port during a standby mode of not performing imprinting, and the flow rate of clean air in the space is reduced or clean air is not sent during an imprinting mode.
