  • Publication number: 20240119296
    Abstract: A learning device calculates an estimation target item reference value according to a fixed value of each estimation target object. The learning device acquires learning data that includes the fixed value of each estimation target object, a variable item value, and an estimation target item value according to the fixed value and the variable item value. The learning device trains, using the learning data and an evaluation function, a model that outputs an estimated value of the estimation target item value in response to input of the fixed value of each estimation target object and the variable item value.

  • Publication number: 20140061970
    Abstract: The present invention provides a nanoimprint curable composition to be used in “nanoimprint lithography” in which a nanoimprint mold is pressed to transfer a fine concave-convex pattern, the nanoimprint curable composition containing a composite resin which has a polysiloxane segment and a polymer segment other than the polysiloxane segment, the polysiloxane segment containing a silanol group and/or hydrolyzable silyl group and having a polymerizable double bond. In addition, the present invention provides a nanoimprint-lithographic molded product, resist film, resin mold, and method for forming a pattern, which each involves use of the nanoimprint composition.
