Abstract
We introduce and compare two methods to produce the phase-shift patterns, which are widely generated in the near-field lithography, in the optical far field. The key component of the two methods is a phase-only diffractive optical element, a similar function found in the maskless lithography. The technique to produce a smaller feature size was a major improvement beyond the diffraction limit.
