Patent ID: 6914258

Claim:
A field effect transistor sandwiched organic semiconductor, comprising: a substrate ( 1 ), a gate electrode ( 2 ) formed on the surface of the substrate ( 1 ), a gate insulation layer ( 3 ) formed on the substrate ( 1 ) and the gate electrode ( 2 ), which is characterized in that, further comprising: an organic active layer ( 4 ) formed on the gate insulation layer ( 3 ), or meanwhile leaving a part of the gate insulation layer ( 3 ) to be exposed, a source and drain electrodes ( 5 ) formed on a part of the gate insulation layer ( 3 ) and a part of the organic active layer ( 4 ), an active layer ( 6 ) formed on the exposed part of the gate insulation layer ( 3 ), the organic active layer ( 4 ), the source electrode and the drain electrode ( 5 ).
