Abstract

The invention relates to an electronic component made primarily from organic materials with high resolution structuring, in particular to an organic field effect transistor (OFET) with a small source-drain distance, and to a production method thereof. The organic electronic component has depressions and/or modified regions in which the conductor tracks/electrodes, which can be metallic, for example, are arranged, and which have been produced by means of a laser during production.

Claims

1. An electronic component made from primarily organic material, comprising:

an electrically insulating substrate and/or lower layer having a depression formed by a laser; and

at least one electrical conductor track and/or electrode in the depression, the depression having steep walls, sharp contours and a relatively rough bottom surface, the at least one conductor track and/or electrode comprising at least one electrically conductive material for interconnecting electrical components on the substrate.

2. The electronic component as claimed in claim 1, having at least two conductor tracks and at least two electrically conductive electrodes and a distance l smaller than 10 μ

m between the two conductor tracks, the at least two electrodes and/or between a conductor track and an electrode.

3. The electronic component as claimed in claim 1 wherein the conductor track and/or electrode comprises at least one metallic layer or metal alloy layer.

4. The electronic component as claimed in claim 1 wherein at least one layer of the conductor track is organic material.

5. A method for producing an organic electronic component with a conductor track or electrode, the component having an insulating lower layer and/or a substrate, the method comprising treating the lower layer and/or substrate with a laser such that at least one depression and/or one modified region are formed in the lower layer and/or the substrate, then filling the depression and/or modified region with an electrically conductive material to thereby produce the conductor track and/or electrode from the electrically conductive material for interconnecting electrical components.

6. The method as claimed in claim 5, including the step of mechanically structuring the electrically conductive material.

7. The method as claimed in claim 5 in which superfluous electrically conductive material is produced, the method including wiping off the superfluous conductive material in a process step following the application of the layer.

8. The method as claimed in claim 6 including forming the at least one depression and/or one modified region with a pulsed laser.

9. The method as claimed in claim 6 which is carried out in a continuous roll-to-roll process.

10. The method as claimed in claim 5 wherein the electrically conductive material is metallic.
