Abstract:
A method for forming a capacitor comprising:providing a silicon-containing region of a substrate assembly; forming a first electrode on at least a portion of the silicon-containing region of the substrate assembly, the forming of the first electrode comprising: forming an adhesion layer of RuSixOy, wherein the RuSixQy adhesion layer is formed by chemical vapor deposition using a ruthenium precursor and a silicon precursor and where x and y are in a range of about 0.01 to about 10; and forming one or more conductive layers relative to the RuSixOy adhesion layer, the one or more conductive layers formed of at least one of a metal or a conductive metal oxide; providing a high dielectric constant material over at least a portion of the first electrode; and providing a second electrode over the high dielectric constant material.
