Abstract
Lithography for printing rough patterns with widths of 1-10 mum in a large area is widely applied for fabricating various micromechanical components. Since the production volume is usually far smaller than that for universal electronics devices, however, expensive lithography systems are not easily adopted to the production. In this research, a novel low-cost projection exposure system is proposed, and its feasibility is investigated. A gradient-index lens array is used as the projection optics, and the array is scanned. The light intensity distribution caused by the array structure is investigated and the highly resoluble potential is clarified.
