    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: 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.
