Abstract:
A method of forming a capacitor comprising:providing a substrate comprising a node location disposed between two conductive lines, each of the conductive lines comprising a conductive portion and an insulative cap formed on the conductive portion, the insulative cap having an uppermost surface; forming a first contact structure joined with the node location, the first contact structure comprising an upper surface entirely elevationally at or below the uppermost surface of the insulative cap; forming a second contact structure joined with the first contact structure; forming a first container over the second contact structure, the first container being electrically joined with the node location through the first and second contact structures, the first container having an opening defining a first interior area; forming a second container over the second contact structure, the second container being electrically joined with the node location through the first and second contact structures, the second container having an opening defining a second interior area, the first and second interior areas being spaced apart from one another in a non-overlapping relationship; and forming a dielectric layer and a conductive capacitor electrode layer disposed operably proximate the first and second containers.
