Abstract:
1. A method of forming a capacitor, said method comprising: forming, above a substrate, a layer comprising a first portion and two second portions on opposite sides of said first portion; forming above said second portions two parallel nodes; forming a plurality of vertical conductive plates above said first portion such that said conductive plates are alternately connected at connecting points to one of said two parallel nodes and such that said conductive plates are separated by spaces that are filled with a dielectric material; and after said forming of said conductivity plates, reducing a size of said spaces such that a first spacing between said connecting points of adjacent conductive plates connected to different ones of said two parallel nodes, as measured along an x-axis, is greater than a second spacing between main bodies of said adjacent conductive plates; further comprising, after said reducing, depositing over said conductive plates a second dielectric material that has a different dielectric constant than said first dielectric material.
