Backside lithography with a moving mask UV exposure technique is proposed. A novel moving-mask exposure apparatus was developed and evaluated both experimentally and through exposure simulations. The backside exposure using this technique was validated and is capable of producing tapered microstructures of thick photoresist for molding. The shape of the structure can be modified by the trajectory of the stage movement. It was confirmed that the shape of the processed structure could be successfully predicted using the proposed simulation method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
