Abstract:
1. A method, comprising: providing a planar workpiece surface that includes a first surface region having a first wettability coefficient and a second surface region having a second wettability coefficient, wherein the first and second surface regions are co-planar and where second wettability coefficient is different from the first wettability coefficient, wherein the second surface region includes first and second sub-region surfaces which are separated from one another by the first surface region, and wherein the first and second sub-region surfaces have first and second lengths, respectively, wherein the first length is different from the second length; dispensing a liquid corresponding to an optical structure on the first and second surface regions of the workpiece, wherein the liquid self-aligns to the first and second sub-region surfaces due to the difference between the first and second wettability coefficients; and hardening the self-aligned liquid to form a first optical structure on the first sub-region surface and a second optical structure on the second sub-region surface.
