Abstract
A method of fabricating a micro lens, the method including: forming a photo-sensitive film on a substrate; placing a photo mask at a predetermined distance from a top of the photo-sensitive film; exposing the photo-sensitive film by varying an area of exposure of the photo-sensitive film so as to selectively expose three-dimensional structures of the photo-sensitive film corresponding to desired micro lenses; and developing the photo-sensitive film such that the exposed three-dimensional structures remain. Also, there is provided a method of fabricating a master for a micro lens, in which a master material is applied on the photo-sensitive film with the three-dimensional structures to form a master having the three-dimensional structures transferred thereonto.
