Abstract
The present invention relates to a dielectric filling for electrical wiring planes of an integrated circuit. The electrical wiring of the integrated circuit comprises a base body on which track and passivation planes can already be disposed; a conductive layer which is disposed on the base body and is patterned in such a manner that it exhibits a first conductor track, a second conductor track and a trench between the first conductor track and the second conductor track; at least one dielectric layer is disposed on the conductive layer and at least partially fills the trench, the preferred material of the dielectric layer being the polymer material polybenzoxazole.
