Abstract:
A microlens manufacturing method using X-ray lithography, comprising of steps of:(a) positioning an X-ray mask for manufacturing the microlens on a substrate on which a sensitive film is formed, and arranging a rotation axis of the substrate and a central axis of the X-ray mask; (b) applying X-rays to the X-ray mask to expose the sensitive film while fixing the X-ray mask and rotating the substrate; and (c) developing the sensitive film to form the microlens, wherein the X-ray mask comprises: a mask substrate permeating the X-rays; a holder fixedly installed on the mask substrate and defining a hole; and an absorbing member including an inserter removably formed in the hole, and having a microlens form, for absorbing the X-rays.
