Abstract:
Techniques for fabricating slanted surface-relief structures are disclosed. In some embodiments, a method for of fabricating a target slanted surface-relief structure, such as a nanoimprint lithography (NIL) mold or a slanted surface-relief grating, includes manufacturing a preliminary surface-relief structure that includes a plurality of ridges and modifying a parameter of the preliminary surface-relief structure to make the target slanted surface-relief structure. The parameter includes a width of each of the plurality of ridges, a height of each of the plurality of ridges, a surface energy of the preliminary surface-relief structure, or a slant angle of an edge of the plurality of ridges. Modifying the parameter includes depositing a material layer on the preliminary surface-relief structure and etching or surface-treating the material layer.

Claim (Index 4):
The method of  claim 3 , wherein modifying the parameter of the preliminary surface-relief structure comprises:\n depositing a spacer layer on the preliminary surface-relief structure; and anisotropically etching the spacer layer to remove the spacer layer on top of the plurality of ridges and the spacer layer between the plurality of ridges, and to keep the spacer layer on sidewalls of the plurality of ridges.
