Force‐ and Time‐Dependent Feature Size and Shape Control in Molecular Printing via Polymer‐Pen Lithography

Year: 2009

Type: article

Abstract: Polymer-pen lithography is a scanning-probe contact-printing method that can control feature diameter from many micrometers to sub-100nm in a single writing operation as a result of force- and time-dependent ink transport. A quantitative model that relates the force between the elastomeric tips and the substrate to the feature edge length has been derived and experimentally confirmed (see image).
