An organic field-effect transistor is disclosed in which an insulating layer having a thickness of 0.3 m or less is provided on a substantially planar electrode layer. This transistor has a channel length down to 2 m, satisfying the condition for voltage amplification well below 10V, and has an on/off ratio of about 25.

Field-effect transistor substantially consisting of organic materials

A practical method of manufacturing an organic field-effect transistor is disclosed. By applying the insulating layer, preferably having a thickness of 0.3 &mgr;m or less to a substantially planar electrode layer, an organic field-effect transistor can be made having a channel length down to 2 &mgr;m, satisfying the condition for voltage amplification at voltages well below 10 V, and having an on/off ratio of about 25.

Method of manufacturing a field-effect transistor substantially consisting of organic materials

A simple and reliable method of providing a vertical interconnect between thin-film microelectronic devices is provided. In said method, a tool tip is used to make a notch in a vertical interconnect area of two organic electrically conducting areas separated from each other by an organic electrically insulating area. The method is used in the manufacture of integrated circuits consisting substantially of organic materials.
