Abstract
Focused Ion Beam (FIB) was employed to fabricate nanoimprint stamps. Complex three dimensional (3D) micro-nano patterns were fabricated including the emblems of Beijing 2008 Olympic Games and Shanghai 2010 World Expo on a single stamp. These micro/nano structures were then faithfully replicated to SU-8 2000.1 resist, with low imprint temperature. Field emission-scanning electron microscope (FE-SEM) and atomic force microscopy (AFM) were used to characterize both stamp and replica's surface profile and replication fidelity. The results show that nanoimprint with the FIB fabricated stamps can successfully replicate complex 3D micro-nano SU-8 structures at the same time under low temperature.
