Abstract
A template () having a first surface (), usable for transferring a pattern of the first surface to an object () having a second surface () covered by a light-sensitive coating (), by contacting the patterned first surface with the coating, wherein the template comprises a carrier base () of e.g. nickel, and a waveguide () is disposed on the carrier base at the first surface. The waveguide is devised to lead light therein, introduced at a radiation input, and to leak evanescent waves to portions () of the coating corresponding to said pattern. The template may also be devised with an opaque shield (), disposed at the first surface over selected portions of the waveguide, which serves to define where the evanescent waves can leak to the coating. The invention also relates to a method and an apparatus for using the template, and a method for manufacturing it.
