Treating an imprint lithography template includes heating the template to desorb gases from the template. Heating the template includes radiating the template at a selected wavelength with, for example, infrared radiation. The selected wavelength may correspond to a wavelength at which the template material is strongly absorbing.03-25-2010
20100084376NANO-IMPRINT LITHOGRAPHY TEMPLATES - Porous nano-imprint lithography templates may include pores, channels, or porous layers arranged to allow evacuation of gas trapped between a nano-imprint lithography template and substrate.

20100109201Nano-Imprint Lithography Template with Ordered Pore Structure - A nano-imprint lithography template includes a non-porous base layer, a cap layer, and a porous layer between the base layer and the cap layer. The porous layer defines a multiplicity of pores and has an ordered pore structure.

The porous layer provides high porosity with a Young's modulus and hardness that are advantageous for imprint lithography processes.05-06-2010
20110180127SOLAR CELL FABRICATION BY NANOIMPRINT LITHOGRAPHY - Fabricating a solar cell stack includes forming a nanopatterned polymeric layer on a first surface of a silicon wafer and etching the first surface of the silicon wafer to transfer a pattern of the nanopatterned polymeric layer to the first surface of the silicon wafer. A layer of reflective electrode material is formed on a second surface of the silicon wafer. The nanopatterned first surface of the silicon wafer undergoes a buffered oxide etching. After the buffered oxide etching, the nanopatterned first surface of the silicon wafer is treated to decrease a contact angle of water on the nanopatterned first surface. Electron donor material is deposited on the nanopatterned first surface of the silicon wafer to form an electron donor layer, and a transparent electrode material is deposited on the electron donor layer to form a transparent electrode layer on the electron donor layer.07-28-2011
