    摘要: 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 cap layer is permeable to helium, and the pores in the porous layer are configured to accept gas passing through the cap layer during an imprint lithography process. The porous layer provides high porosity with a Young's modulus and hardness that are advantageous for imprint lithography processes.

    摘要: An imprint lithography template includes a porous material defining a multiplicity of pores with an average pore size of at least about 0.4 nm. The porous material includes silicon and oxygen, and a ratio of Young's modulus (E) to relative density of the porous material with respect to fused silica (ρporous/ρfused silica) is at least about 10:1. A refractive index of the porous material is between about 1.4 and 1.5. The porous material may form an intermediate layer or a cap layer of an imprint lithography template. The template may include a pore seal layer between a porous layer and a cap layer, or a pore seal layer on top of a cap layer.

    摘要: 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.

    摘要: A solid layer is formed by applying a multiplicity of discrete portions of a fluid composition onto a surface of an imprint lithography substrate, and allowing the discrete portions of the composition to spontaneously spread on the surface of the substrate to form a substantially continuous layer. The composition includes a solvent and a solid or a solvent and a polymerizable material. The composition can be a solution or a dispersion. At least some of the solvent is evaporated from the composition, and a solid layer is formed (e.g., polymerized or dried) on the substrate. The solid layer is substantially free of interstitial voids.
