Abstract
Embodiments herein provide relatively permanent labeling of an imprint lithography template. The imprint lithography template generally has first and second sides, one side having a pattern to imprint a substrate and the other being optically smooth to unobstructably pass UV light. In one embodiment, a method of labeling the imprint lithography template includes placing a masking layer on a portion of the first side (e.g., the optically smooth side) of the template, forming a liftoff layer on the remainder of the first side of the template, removing the masking layer to expose the portion of the first side of the template, and placing a polymer mark on the exposed portion of the first side of the template. The method also includes depositing an opaque material on the first side of the template and removing the liftoff layer and the mark to form a label on the first side of the template with the deposited opaque material.
