Patent ID: 7943477

Claim:
A method of forming a container capacitor, the method comprising: forming a first insulating material over a semiconductor substrate; forming an opening within the first insulating material; forming a barrier conductive material over the insulating material and along sidewalls and a bottom of the opening; forming a lower electrode along sidewalls and a bottom of portions of the barrier conductive material disposed within the opening, wherein forming the lower electrode comprises: forming a lower electrode material above the barrier conductive material and along sidewalls and the bottom of portions of the barrier conductive material within the opening, forming a photoresist plug over the lower electrode material disposed within the opening, removing a portion of the lower electrode material that is not within the opening, and removing the photoresist plug; removing a portion of the barrier conductive material that is not within the opening; forming a dielectric material over the first insulating material and along sidewalls and a bottom of the lower electrode; and forming an upper electrode over the dielectric material.
