Abstract
We proposed a cost-effective and compact optical setup for laser Interference lithography. The system is based on the special designed wave-front splitting prisms with only one spatial filter for two and tree coplanar beams interference. This configuration allows to reduce the total size of the setup. Employing a low coherence laser diode source allows to reduce the price and the size of the setup as well. The coherence length of the source was improved by Littrow type external cavity configuration. The patterning on large area (1 cm2) with sub-micron resolution was successfully demonstrated.
