Abstract

Separation of an imprint lithography template and a patterned layer in an imprint lithography process may result in stress to features of the template and/or features of the patterned layer. Such stress may be reduced by minimizing open areas on the template, including dummy features within the open areas, and/or selective positioning of features on the template.
