Defect analysis and lifetime evaluation of a release-coated nanoimprint mold
The lifetime of the release agent on nanoimprint lithography were evaluated. Lifetime is usually evaluated by measuring the release force and the contact angle. We introduce the error rate as a new means of the lifetime of release coatings. The error rate for OPTOOL DSX-coated was less than that for C8H4Cl3F13Si-coated. We found mixing OPTOOL DSX with C8H4Cl3F13Si resulted in a lower overall error rate.
