Abstract:
1. A capacitor device, comprising: a semiconductor substrate having at least one active device; at least one capacitor device formed in a predetermined region of said semiconductor substrate, said capacitor device comprising: a bulk dielectric material positioned in said predetermined region of said semiconductor substrate; a plurality of first electrode plates extending vertically from one surface of said semiconductor substrate into said bulk dielectric material, each first electrode plate being disposed parallel to one another; a first common conducting line formed on said surface of said semiconductor substrate and electrically connecting said first electrode plates; a plurality of second electrode plates extending vertically from said surface of said semiconductor substrate into said bulk dielectric material and interdigitating parallel to said first electrode plates; a second common conducting line formed opposite to said first common conducting line on said surface of said semiconductor substrate and electrically connecting said second electrode plates; and a first vertical conducting line, a first parallel conducting line, a second vertical conducting line and a second parallel conducting line, said first vertical conducting line extending through said semiconductor substrate and said first parallel conducting line, which is formed on said surface of said semiconductor substrate and electrically connecting said first vertical conducting line with a first electrode plate closest to the outside; and said second vertical conducting line formed opposite to said first vertical conducting line and extending through said semiconductor substrate and said second parallel conducting line, which is formed on said surface of said semiconductor substrate and electrically connecting said second vertical conducting line with a second electrode plate closest to the outside.
