Each micro-channel has micro-channel walls and a micro-channel bottom, the micro-channel bottom having distinct first and second portions. Deposited material is located on the micro-channel walls and not on the second portion of the micro-channel bottom. ## Claims ### Claim 1 A high-aspect-ratio imprinted structure, comprising: a first layer of cured layer material having a surface and a plurality of micro-channels imprinted in the first layer, each micro-channel having a length, micro-channel walls, and a micro-channel bottom, the micro-channel bottom having distinct first and second portions; and deposited material located on the micro-channel walls and not on the second portion of the micro-channel bottom, wherein the micro-channels extend over the first layer to define a length, and wherein the micro-channels and the deposited material on the micro-channel walls have a substantially rectangular cross section taken in a direction perpendicular to the length of the micro-channels and perpendicular to the surface of the first layer, and wherein the deposited material has a transmissivity of less than 50% and is not present on the surface of the first layer. ### Claim 2 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 further including a second layer over the first layer and the deposited material. ### Claim 3 (depends on 2) The high-aspect-ratio imprinted structure of claim 2 wherein the second layer includes the cured layer material. ### Claim 4 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 further including a cured filler material in each micro-channel between the deposited materials and on only the second portion of the micro-channel bottom. ### Claim 5 (depends on 4) The high-aspect-ratio imprinted structure of claim 4 wherein the cured layer material is the same as the cured filler material. ### Claim 6 (depends on 4) The high-aspect-ratio imprinted structure of claim 4 further including a second layer over the first layer, the deposited material, and the cured filler material. ### Claim 7 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channels extend only partially through the first layer. ### Claim 8 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channels extend through the first layer. ### Claim 9 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 further including a substrate having a surface on which the first layer is located. ### Claim 10 (depends on 9) The high-aspect-ratio imprinted structure of claim 9 wherein the substrate surface is a display cover or a display substrate. ### Claim 11 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 2. ### Claim 12 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 5. ### Claim 13 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 10. ### Claim 14 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 20. ### Claim 15 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material is a metal or includes a metal. ### Claim 16 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channels are spaced apart by an amount greater than or equal to the width of the micro-channel. ### Claim 17 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the first cured material is a cross-linked material, a resin, or a polymer. ### Claim 18 (depends on 1) The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channel has a cross section parallel to the surface of the first layer that is not rectangular. ### Claim 19 (depends on 6) The high-aspect-ratio imprinted structure of claim 6, wherein the first and second layers are cross linked or wherein the second layer and filler material are cross linked. ### Claim 20 (depends on 1) The high-aspect-ratio imprinted structure of claim 1, wherein the high-aspect-ratio structure is a privacy screen, a wire grid polarizer, a plasmonic device, or a grating.
