Paper Abstract

In this paper, we propose a self-assembled microlens arrays (MLAs) on top of light emitting diodes (LEDs) based on hydrophilic effect by UV/ozone treatment. After hydrophilic zones were produced by UV/ozone treatment, the substrate with hydrophilic zones was dipped in and out of diluted SU-8 solution with slow and constant velocity. Finally, MLA was formed after UV curing and baking. By this approach, the fabrication is low cost and low time-consuming.
