Patent number: 12032285Abstract: A method and system for imprinting a substrate supported on a moveable stage is provided and includes contacting a liquid resist on the substrate with a template and aligning the substrate with the template using a feedback-feedforward control process with a first set of control parameters. Calibration data is obtained and the viscosity of at least a portion of the resist is increased. The substrate is then with the template using the feedback-feedforward control process with a second set of control parameters after the viscosity of the resist has increased, the second set of control parameters are determined based on the calibration data and the resist is cured under the template.Type: GrantFiled: February 9, 2023Date of Patent: July 9, 2024Assignee: Canon Kabushiki KaishaInventors: Mingji Lou, Takahiro Yoshida, Steven T. Jenkins, Kenichi Kobayashi, Tatsuya Arakawa
