Abstract:
1. A method for separating a stamper from a patterned substrate, the method comprising: providing a substrate having a top and a bottom with an opening therein, the top comprising an imprintable resist layer; providing a support mechanism configured to retain the substrate with a suction force; providing a stamper having a formed pattern and configured to come in contact with the top of the substrate to transfer the formed pattern to the imprintable resist layer, wherein a chamber is formed within the opening of the substrate when the stamper is in contact with the top of the substrate, and wherein the formed pattern comprising nano-scaled features each comprising a width of at most approximately 20 nanometers; providing a channel directed toward the chamber to introduce pressurized air into the chamber; applying a suction force to the substrate to prevent movement of the substrate relative to the support mechanism; and while applying the suction force to the substrate, directing pressurized air through the channel to the chamber to initiate separation of the stamper from the substrate.
