Top gate pentacene thin film transistor with spin-coated dielectric

Fabrication of top gate pentacene thin film transistor (TFT) is made possible with spin-coatable dielectrics by the technique presented here. Such fabrication has been impractical because of the ill effects a solvent can have on pentacene. A bilayer of pentacene on insulator that are coated on a mold is transferred to a glass substrate on which source and drain electrodes are defined. In the transfer process, pentacene is automatically patterned. This fabrication method allows for the channel length to be as small as photolithography would permit.
