The surface profile of Fresnel lens during the fabrication process depends on many factors including the thickness, flatness, and pattern clarity of a photoresist (PR) film used as a hard mask for the Si lithography. SU-8 PR with a high viscosity, which is capable of creating large thickness films, can be used as a hard mask in the Fresnel lens fabrication processes. However, it is not easy to achieve a film thickness of about 10 µm with the requirement of a flat surface, free of air bubbles after the baking phases.
