Dry patterning of a variety of solution‐ and vapor‐deposited small‐molecule organic semiconductors using adhesive tape is demonstrated. This technique allows direct fabrication of large‐area arrays of bottom‐contact high‐performance organic‐ thin‐film field‐effect transistors with self‐aligned electrodes. These patterned devices exhibit significantly higher on/off ratios and lower parasitic leakage currents than control unpatterned devices of the same materials.
