Abstract
Methods of forming a capacitor including forming a titanium nitride material within at least one aperture defined by a support material, forming a ruthenium material within the at least one aperture over the titanium nitride material, and forming a first conductive material over the ruthenium material within the at least one aperture. The titanium nitride material may be oxidized to a titanium dioxide material. A second conductive material may be formed over a surface of the titanium dioxide material. A semiconductor device may include at least one capacitor, wherein a major longitudinal portion of the at least one capacitor is not surrounded by a solid material. The capacitor may include a first electrode; a ruthenium oxide material laterally adjacent the first electrode; a rutile titanium dioxide material laterally adjacent the ruthenium oxide material; and a second electrode laterally adjacent the rutile titanium dioxide material.
