21_12/2009“Dry” Patterning: Direct Patterning of Organic-Thin-Film-Transistor Arrays via a “Dry-Taping” Approach (Adv. Mater. 12/2009)

The cover shows the patterning of several solution- and vapor-deposited small molecule organic semiconductors using a dry taping approach. Zhenan Bao and co-workers demonstrate on page 1266 that this technique allows direct fabrication of large area arrays of bottom-contact high-performance organic thin-film field-effect transistors with self-aligned electrodes. Patterned devices exhibit significantly higher On/Off ratios and lower parasitic leakage than unpatterned ones.
