Described are imprint lithography templates, methods of forming and using
the templates, and a template holder device. An imprint lithography
template may include a body with a plurality of recesses on a surface of
the body. The body may be of a material that is substantially transparent
to activating light. At least a portion of the plurality of recesses may
define features having a feature size less than about 250 nm. A template
may be formed by obtaining a material that is substantially transparent
to activating light and forming a plurality or recesses on a surface of
the template. In some embodiments, a template may further include at
least one alignment mark. In some embodiments, a template may further
include a gap sensing area. An imprint lithography template may be used
to form an imprinted layer in a light curable liquid disposed on a
substrate. During use, the template may be disposed within a template
holder. The template holder may include a body with an opening configured
to receive the template, a support plate, and at least one piezo actuator
coupled to the body. The piezo actuator may be configured to alter a
physical dimension of the template during use.
