Abstract
First-generation, full-wafer exposure, X-ray lithography equipment has been in continuous operation since 1979 in a pilot line application.(1,2,3) Second-generation, full-wafer exposure systems that incorporate the latest advancements in X-ray lithography are now being developed for early, submicron, VLSI patterning. This paper discusses recent advances in E-beam gun design and high-speed rotating anode development in terms of X-ray lithographic performances such as resolution and image contrast. In addition, the performance of a physical optics alignment technique that is compatible with submicron IC pattern overlay requirements is reported. The Perkin-Elmer X-100 full-wafer exposure system is a valuable development tool because of its flexibility. It is compatible with all X-ray masks and resists and can be used to expose either 75 mm or 100 mm diameter wafers.
