Abstract:
An imprinting apparatus includes a silicon master having a plurality of nanofeatures defined therein. An anti-stick layer coats the silicon master, the anti-stick layer including a molecule having a cyclosiloxane with at least one silane functional group. A method includes forming a master template by: depositing a formulation on a silicon master including a plurality of nanofeatures defined therein, the formulation including a solvent and a molecule having a cyclosiloxane with at least one silane functional group; and curing the formulation, thereby forming an anti-stick layer on the silicon master, the anti-stick layer including the molecule. The method further includes depositing a silicon-based working stamp material on the anti-stick layer of the master template; curing the silicon-based working stamp material to form a working stamp including a negative replica of the plurality of nanofeatures; and releasing the working stamp from the master template.
