Conductive structure based on poly-3,4-alkenedioxythiophene (PEDOT) and polystyrene sulfonic acid (PSS)

摘要

An electronic component has an electrically conductive relief structure (3), which contains a salt of a poly-3,4-alkylenedioxythiophene. This salt provides the structure with a stable conductivity. The salt is a polyacid salt by preference. In the method of manufacturing a relief structure on an electrically insulating substrate the polyacid salt of poly-3,4-alkylenedioxythiophene is used. Relief structures (3) comprising tracks (311-314, 321-324) and channels (141) with track widths (tW) and channel lengths (cL) of less than 10 µm can be achieved. The tracks (311-314; 321-324) are used as electrodes (31;32), the channels (141) are used as semiconductor channels in electronic components, especially in field-effect transistors (11) and light-emitting diodes.
