Abstract: Microcontact printing (μCP), a cost-effective replication method, is an alternative to the conventional electron beam or X-ray lithography technique to create microstructure patterns. But the resolution problem in microcontact printed structures is a major user concern. A μCP technique to focus on the deformation effect of different printing time and printing pressure on the microcontact printed structures is revealed in this paper. To study the deformation effect, cost-effective μCP channels of self-assembled monolayers (SAMs) of alkanethiol has been prepared on gold (Au) surface. The alkanethiol inking the polydimethylsiloxanes (PDMS)stamp effectively forms the SAMs on the noble Au surface that protects the metal against etchant solution and thereby forms channel-like structures. To address the deformation issue, various printing time and printing pressure have been reported. The estimation of differing channel width and channel space with varying printing time and pressure shows the best resolution structures printed under minimal printing time at atmospheric pressure.
