ABSTRACT:
An arrangement for interconnecting high density signals of integrated circuits includes an electronic circuit on a multilayered substrate which includes at least three layers. These layers comprise a signal layer for carrying signals in the electronic circuit, a dielectric layer of organic material disposed adjacent the signal layer, and a metallic reference layer. The layers are disposed such that the dielectric layer is between the signal layer and the metallic reference layer. For providing controlled line impedance and for reducing cross-talk between the signals carried in the electronic circuit, the metallic reference layer includes uniformly spaced apertures which are situated in a slanted grid arrangement.
