Abstract
An image projection system is provided. The system can be used for performing lithography. The system includes a deuterium light source, a converging lens coupled to the deuterium light source. The system includes an aperture configured to provide image tiling disposed adjacent to the converging lens. The system includes a movable stage disposed adjacent to the aperture. A method of fabricating an optical device is provided. The method includes depositing a resist over a substrate and determining an exposure pattern for the optical device. The method includes exposing a portion of the resist with a light beam based on the determined exposure pattern. Exposing the portion of the resist includes directing the light beam from a deuterium light source to the substrate and developing the resist.
