Abstract:
1. A method of forming a capacitor, comprising: forming a titanium nitride material within at least one aperture defined by a support material; forming a ruthenium material over the titanium nitride material within the at least one aperture; oxidizing a portion of the ruthenium material to a ruthenium oxide material; forming a first electrode comprising a conductive material over the ruthenium oxide material within the at least one aperture, the ruthenium material laterally surrounding the conductive material and the ruthenium oxide material laterally adjacent the first electrode; oxidizing the titanium nitride material to a rutile titanium dioxide material, the rutile titanium dioxide material laterally adjacent the ruthenium oxide material; and forming a second electrode comprising a conductive material over a surface laterally adjacent to the rutile titanium dioxide material, wherein a major longitudinal portion of the capacitor is not surrounded by a solid material.
