S. Liu, H. A. Becerril, M. C. LeMieux, W. M. Wang, J. H. Oh, Z. Bao, “Direct Patterning of Organic-Thin-Film-Transistor Arrays via a “Dry-Taping” Approach”, Adv. Mater. 2009, 21, 1266–1270.

[Featured as a Cover Paper]

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.
