Paper Abstract
The Micrascan I system, a new 0.5-micron lithography tool, employs a 'step-and-scans concept that combines the virtues of ring-field scanning systems with those of conventional step-and-repeat systems. Individual exposure fields on the wafer are sequentially scanned past the arcuate image field of a catadioptric projection optics system with a 4:1 reduction ratio. The reticle is scanned in precisely coordinated fashion by a separate stage. Exposure illumination is provided by a long-life mercury-xenon arc lamp. The concept enables very large field sizes and high system productivity.
