Abstract
A method of forming a device includes emitting a coherent light beam and providing a mask including a region transparent to the light beam. The method further includes projecting the light beam on a photosensitive layer through the transparent region of the mask. The method further includes forming a recess in the photosensitive layer, wherein the recess corresponds to a position of the transparent region of the mask. The method further includes filling an organic light emitting material in the recess.
