Microcontact Printing as a Versatile Tool for Patterning Organic Field-Effect Transistors

Patterning of organic field‐effect transistors can be easily accomplished by microcontact printing combined with subsequent electroplating and electrode‐peeling transfer. The method is based on area‐selective electrodeposition and diffusion electropolymerization performed on metallized substrates with a previously patterned self‐assembled monolayer, which is used as a template in the subsequent deposition of drain and source contacts (see Figure).
