Hybrid organic thin layered field effect transistor for use in polymer circuit, has source and drain electrodes including thin copper layer whose surface area facing semiconductor layer is modified to form copper oxide layer between layers

摘要

The transistor has a substrate base (1) made of thin, flexible polyethylene foil, and source and drain electrodes (2, 3) arranged on the substrate base. The electrodes are designed as flat electrodes. The electrodes have a thin copper layer whose surface area facing the organic semiconductor layer (4) is modified such that a copper oxide layer is formed as an intermediate layer between the copper layers and the semiconductor layer. The copper layers are structured by UV lithographic process and standard etching process. An independent claim is also included for a method for manufacturing an organic field effect transistor.
