Claim of US Patent No. 10,091,890

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 scratching 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.
