摘要: Densifying a multi-layer substrate includes providing a substrate with a first dielectric layer on a surface of the substrate. The first dielectric layer includes a multiplicity of pores. Water is introduced into the pores of the first dielectric layer to form a water-containing dielectric layer. A second dielectric layer is provided on the surface of the water-containing first dielectric layer. The first and second dielectric layers are annealed at temperature of 600° C. or less. In an example, the multi-layer substrate is a nanoimprint lithography template. The second dielectric layer may have a density and therefore an etch rate similar to that of thermal oxide, yet may still be porous enough to allow more rapid diffusion of helium than a thermal oxide layer.

摘要: 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. The pores or channels may be formed by etch or other processes. Gaskets may be formed on an nano-imprint lithography template to restrict flow of polymerizable material during nano-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: A silicon nanowire array including a multiplicity of silicon nanowires extending from a silicon substrate. Cross-sectional shape of the silicon nanowires and spacing between the silicon nanowires can be selected to maximize the ratio of the surface area of the silicon nanowires to the volume of the nanowire array. Methods of forming the silicon nanowire array include a nanoimprint lithography process to form a template for the silicon nanowire array and an electroless etching process to etch the template formed by the nanoimprint lithography process.

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.

One such photovoltaic cell includes a first electrode and a first electrically conductive layer electrically coupled to the first electrode. The first conductive layer has a multiplicity of protrusions and recesses formed by a nano-imprint lithography process. A second electrically conductive layer substantially fills the recesses and covers the protrusions of the first conductive layer, and a second electrode is electrically coupled to the second conductive layer. A circuit electrically connects the first electrode and the second electrode.
