Abstract
This paper reports a novel contact printing method which can transfer patterned metallic films directly from a mold to a substrate, based on applied contact pressure and infrared pulse laser heating. Experiments have been carried out using a 1064 nm pulsed Nd:YAG laser to demonstrate the feasibility of the proposed method. Chromium (Cr) films of 70 nm thickness with both array-dot patterns and linear grating patterns of typically 500 nm feature sizes are successfully transferred. The transferred Cr patterns can serve as an etching mask for the subsequent etching on the substrate. The potential for applying this method to nano-patterning and nano-fabrication is addressed.
