High-aspect-ratio imprinted structure

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.

2. The high-aspect-ratio imprinted structure of claim 1 further including a second layer over the first layer and the deposited material.

3. The high-aspect-ratio imprinted structure of claim 2 wherein the second layer includes the cured layer material.

4. 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.

5. The high-aspect-ratio imprinted structure of claim 4 wherein the cured layer material is the same as the cured filler material.

6. 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.

7. The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channels extend only partially through the first layer.

8. The high-aspect-ratio imprinted structure of claim 1 wherein the micro-channels extend through the first layer.

9. The high-aspect-ratio imprinted structure of claim 1 further including a substrate having a surface on which the first layer is located.

10. The high-aspect-ratio imprinted structure of claim 9 wherein the substrate surface is a display cover or a display substrate.

11. The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 2.

12. The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 5.

13. The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 10.

14. The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material has a cross section having an aspect ratio greater than 20.

15. The high-aspect-ratio imprinted structure of claim 1 wherein the deposited material is a metal or includes a metal.

16. 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.

17. The high-aspect-ratio imprinted structure of claim 1 wherein the first cured material is a cross-linked material, a resin, or a polymer.

18. 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.

19. 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.

20. 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.
