24_46i/2012Organic Semiconductors: Dry Lithography of Large-Area, Thin-Film Organic Semiconductors Using Frozen CO2 Resists (Adv. Mater. 46/2012)

Frozen carbon dioxide can be used as a phase-change resist to perform dry lithography of organic thin films, as shown by Matthias E. Bahlke and co-workers on page 6136. The resist sublimes closest to the surface, separating the still-solid resist that in turn lifts off undesired organic material. This new technique will help address the incompatibility of organic semiconductors with traditional photolithography.
