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).
