Patent ID: 8420479

Claim:
A method, comprising: forming a first opening in a dielectric material of a contact level of a semiconductor device, said first opening connecting to a first contact region of a transistor; forming a conductive material and a capacitor dielectric material on inner surface areas of said first opening; forming a second opening in said dielectric material so as to connect to a second contact region of said transistor; and forming a conductive material in said first and second openings, wherein forming said conductive material and said capacitor dielectric material comprises forming a layer of said conductive material above said dielectric material and within said first opening and removing said conductive material from said dielectric material outside said first opening prior to forming said capacitor dielectric material, and wherein removing said conductive material from said dielectric material outside said first opening comprises filling said first opening at least partially with a sacrificial fill material and performing a removal process in the presence of said sacrificial fill material.
