Abstract: Atomic lithography is a technique in which nearly resonant light is used to pattern an atom beam periodically. In this article, a 425 nm laser light standing wave is used to focus a beam of chromium atoms to fabricate the period of the nanoscale pitch standards of 213 ± 0.1 nm. The height was 4 nm. The (FWHM) width is 64 ± 6 nm. And this result will be analysed theoretically. The tracing of atoms is numerical simulated based on particle-optics and the factors of affecting deposition result will be found in this article.

Keywords: nanopitch standards; atomic lithography; cooled atoms; nanoscale pitch standards; nanotechnology; atom tracing; numerical simulation; particle optics.
