Paper Abstract

We introduce a combined e-beam and x-ray lithographic method to fabricate microzone plates (MZP) on free-standing silicon nitride films. An automatic design program is developed to draw the complex layout of MZP with very smooth boundaries. A gold MZP master mask with a minimum ring width of 250 nm is fabricated by e-beam lithography. The master mask is replicated using x-ray lithography (XRL) and nickel electroplating to obtain the final MZP. The combined lithographic technique produces a MZP with a pattern aspect ratio of 4.4:1.
