Paper Abstract

As part of the development of a synchrotron-based x-ray lithography beamline, progress has been made in designing an optics system which meets the current industrial requirements. The primary goals of the optics are to achieve 0.25 micrometers line resolution over a 50-mm-wide by 25-mm-tall exposure field. The beamline optics must also provide a 5% power uniformity over the exposure field and enough power to achieve a 60-wafer-per-hour throughput with 20 exposure fields. In this paper, a description of a beamline optics system is presented for use with the Superconducting X-ray Lithography Source (SXLS) being built by Brookhaven National Laboratory with assistance from the Grumman Corporation. The basic design approach, performance characteristics, and some design data will be discussed.
