Abstract

In this paper, the use of Focused Ion Beam (FIB) milling as an alternative technology to electron-beam lithography in production of complex 3-D-structures such as “Motheye” lenses for Step and Flash Imprint Lithography (S–FIL) templates is discussed. Alterations introduced to conventional template fabrication techniques and the advantages and disadvantages of the proposed template fabrication method over conventional routes are discussed. Comparing the template and replication, we show that the surface topographies are almost identical, and thus FIB milled structures can be consistently replicated employing the S–FIL technology.
