Abstract:
1. A process for producing a circuit arrangement having a layer arrangement, in which two electrically conductive interconnects running substantially parallel to one another are formed on a substrate, comprising; forming at least one auxiliary structure on the substrate and between the two interconnects, running in a first direction, which first direction includes an angle of between 45 degrees and 90 degrees with a connecting axis of the interconnects, running orthogonally with respect to the two interconnects, the at least one auxiliary structure being produced from a material which allows the at least one auxiliary structure to be selectively removed from a dielectric layer; forming the dielectric layer between the two interconnects, in such a manner that the at least one auxiliary structure is at least partially covered by the dielectric layer; and forming a layer of catalyst material for catalyzing the formation of the auxiliary structure between at least part of the substrate and the at least one auxiliary structure.
