Abstract
A two-aspherical-mirror system designed for large-area, high-resolutio n pattern replication has been developed. In order to expand the expos ure area to 20 mm x 25 mm, new critical-illumination optics and a scan ning mask stage synchronized with the wafer stage were developed. Thes e improvements enabled the reduction of patterns in a large exposure f ield.
