Microcontact printing using a flat metal-embedded stamp fabricated using a dry peel-off process

Ikjoo Byun, Anthony W. Coleman, Beomjoon Kim

Abstract

A microcontact printing method using a flat metal-embedded polydimethylsiloxane (PDMS) stamp has been demonstrated. Metal patterns embedded in the PDMS stamp act as a molecular transport barrier. The flat stamp avoids the mechanical deformation of the stamp tip which is a crucial problem when printing the stamp onto a substrate.
