ABSTRACT:
The device of the invention comprises a thin film transistor of an organic semiconductor material. This semiconductor material is patterned by applying first a protective layer and thereafter a photoresist. As a result hereof, the transistor of the invention (A) shows a very low leakage current and a low threshold voltage in comparison with prior art transistors (B,C).
