Abstract:
A method for making a capacitor structure in a substrate comprising the steps of:forming a conductive plug in said substrate;forming a first conductor on said substrate;forming a first non-conductor on top of and substantially in register with the first conductor;defining a first opening in said first conductor and first non-conductor said first opening being substantially aligned with said conductive plug and exposing said substrate;forming a continuous non-conductive sidewall spacer in the first opening;forming a second opening in said continuous non-conductive sidewall spacer whereby said resulting sidewall spacer comprises first and second continuous non-conductive sidewalls and said second opening exposing said substrate; andforming a second conductor in the second opening, wherein said first and second continuous non-conductive sidewalls of said resulting sidewall spacer insulate said first conductor from said second conductor.
