Abstract:
1. A method of fabricating a capacitor in a semiconductor substrate comprising a first surface and a second surface, said method comprising: forming a first dielectric layer directly on a first portion of said first surface of said semiconductor substrate; forming a first electrode layer directly over said first dielectric layer, wherein said first electrode layer is electrically insulated from said semiconductor substrate; forming a second dielectric layer directly on a second portion of said first surface of said semiconductor substrate, wherein said first dielectric layer is separated from said second dielectric layer; forming a second electrode layer directly over said second dielectric layer, wherein said first electrode, said second electrode, said first dielectric layer and said second dielectric layer form a plurality of capacitors in series, and wherein said first and said second electrode layers comprise a plurality of fingers, and wherein a first portion of said first electrode layer is interdigitated with a second portion of said second electrode layer.
