Abstract:
1. In an integrated circuit, the improvement comprising a pressure resistant current carrying structure having: electrically conductive layers for carrying current, a first electrically nonconductive material at least partially surrounding the electrically conductive layers, the first electrically nonconductive material providing electrical insulation between the electrically conductive layers, the first electrically nonconductive material having a first degree of fragility and a first dielectric constant, wherein the first electrically nonconductive material directly contacts and underlies a bottom surface of an overlying electrically conductive layer below which it is disposed and a top surface of an underlying electrically conductive layer above which it is disposed, and a second electrically nonconductive material disposed in a pattern within the first electrically nonconductive material between the electrically conductive layers, the second electrically nonconductive material providing structural support for the first electrically nonconductive material between the electrically conductive layers, the second electrically nonconductive material having a second degree of fragility that is less than the first degree of fragility and a second dielectric constant that is greater than the first dielectric constant, wherein the second electrically nonconductive material directly contacts a bottom surface of an overlying electrically conductive layer below which it is disposed and a top surface of an underlying electrically conductive layer above which it is disposed.
