Abstract:
A process for forming a capacitor on a substrate having circuitry, the process comprising the steps of:depositing a first insulative layer on said substrate;depositing a first conductive layer on said first insulative layer;depositing a second insulative layer on said first conductive layer;depositing a second conductive layer on said second insulative layer;forming a patterning layer on a first region of said substrate, leaving a second region of said substrate exposed;removing said second conductive layer, said second insulative layer, said first conductive layer and said first insulative layer from said second region;depositing a third insulative layer on said first and said second regions;forming openings in said third insulative layer in said first and said second regions;depositing a third conductive layer in said openings; anddepositing an upper level conductive layer on said third insulative layer and said third conductive layer.
