Abstract

The present invention provides combining the advantages of hybrid resist with the unique properties of x-ray lithography to form high tolerance devices with x-ray pitch and to provide a means for varying the space width and fine tuning to account for process variations. Accordingly, a space width in the hybrid resist can be selectively printed by varying the mask-wafer gap distance, allowing more versatile structures to be formed and adjustments to be made for process changes such as resist composition and ion implant levels.
