Abstract

A process of producing a component includes providing a substrate having an electrically conductive surface in the form of an electrically conductive layer; subdividing the layer with the aid of a laser process into a first electrically autonomous region and a second electrically autonomous region, wherein an electrically insulating region is formed in the electrically conductive layer to electrically separate the electrically autonomous regions; forming an electrical potential difference between the first electrically autonomous region and the second electrically autonomous region; and applying an electrically charged substance or an electrically charged substance mixture onto the first electrically autonomous region and/or the second electrically autonomous region, wherein the electrically autonomous region and/or an amount of the applied electrically charged substance or of the electrically charged substance mixture are adjusted by the electrical potential difference.

First claim

The invention claimed is:

1. A process of producing a component comprising:
providing a substrate having an electrically conductive surface in the form of an electrically conductive layer;
subdividing the layer with the aid of a laser process into a first electrically autonomous region and a second electrically autonomous region, wherein an electrically insulating region is formed in the electrically conductive layer to electrically separate the electrically autonomous regions;
forming an electrical potential difference between the first electrically autonomous region and the second electrically autonomous region; and
applying an electrically charged substance or an electrically charged substance mixture onto the first electrically autonomous region and/or the second electrically autonomous region,
wherein the electrically autonomous region and/or an amount of the applied electrically charged substance or of the electrically charged substance mixture are adjusted by the electrical potential difference.

2. The process as claimed in claim 1 , wherein providing the substrate having an electrically conductive surface comprises forming the electrically conductive layer on or over an electrically insulating surface of the substrate.

3. The process as claimed in claim 1 , wherein providing the substrate having an electrically conductive surface comprises forming the electrically conductive layer on or over an electrically insulating surface of the substrate, the electrically insulating surface of the substrate is formed by forming the electrically insulating layer on or over a partially or fully electrically insulating surface of the substrate.

4. The process as claimed in claim 1 , wherein forming the electrically insulating region between the electrically autonomous regions comprises chemical crosslinking or chemical degradation of the substance or substance mixture of the electrically conductive layer or a ballistic process.

5. The process as claimed in claim 1 , wherein forming the potential difference between the first electrically autonomous region and the second electrically autonomous region comprises connecting at least one electrically autonomous region to a voltage source, and forming a first electrode.

6. The process as claimed in claim 1 , wherein, to apply the first electrically charged substance or the first electrically charged substance mixture onto the first electrically autonomous region or the second electrically autonomous region, physical contact of the first electrically autonomous region and/or the second electrically autonomous region with a suspension is formed, wherein the suspension comprises the first electrically charged substance or the first electrically charged substance mixture in a first solvent, and a second electrode is configured in the suspension.

7. The process as claimed in claim 1 , further comprising applying a further electrically charged substance or a further electrically charged substance mixture on or over the first electrically autonomous region or the second electrically autonomous region.

8. The process as claimed in claim 1 , further comprising applying a further electrically charged substance or a further electrically charged substance mixture on or over the first electrically autonomous region or the second electrically autonomous region,
wherein the further application of a further electrically charged substance or of a further electrically charged substance mixture comprises modifying one or more parameters selected from the group consisting of:
the electrical potential difference,

the solvent of the suspension, and
the layer thickness of the applied further electrically charged substance or electrically charged substance mixture.

9. The process as claimed in claim 1 , wherein the component is formed with at least one of a wavelength-converted optoelectronic component or a wavelength-converted light-emitting diode.

10. The process as claimed in claim 1 , wherein the component is formed with at least one of a wavelength-converted optoelectronic component or a wavelength-converted light-emitting diode, and the component is formed with a plurality of wavelength-converted optoelectronic components as a multicolor emitting or absorbing optoelectronic component, or a multicolor light-emitting diode.

11. The process as claimed in claim 1 , wherein a luminophore is applied onto the first electrically autonomous region and a reflector is applied onto the second electrically autonomous region.
