  • Thin film structures with negative inductance and methods for fabricating inductors comprising the same
    Patent number: 7956715
    Abstract: An inductor structure comprising a substrate and a planar conductor structure on a surface of the substrate, and methods for fabricating an inductor structure. The planar conductor structure may comprise a vertical stack of three or more multilayer films. Each multilayer film may comprise a first layer of a first metal, defining a first vertical thickness, and a second layer of a second metal, defining a second vertical thickness. The metals and thicknesses are chosen such that the inductor exhibits a negative electrical self-inductance when an electrical signal is transmitted from a first contact point to a second contact point.
