Abstract:
In a semiconductor device, a structure for conducting current and reducing parasitic effects of currents generated in the semiconductor substrate, said structure comprising:a substrate of semiconductor material;two or more elongated conductors over the substrate, each conductor parallel to the other(s) for at least a portion of their respective lengths and capable of capacitively and inductively inducing current in the substrate; anda single current barrier layer proximate the elongated conductors comprising a plurality of adjacent sequentially and coplanar alternating regions of high conductivity and high resistivity defined within said current barrier layer, boundaries between adjacent said regions oriented transversely with respect to the conductors so that said current barrier layer intercepts and conducts current capacitively generated in the substrate by the conductors and blocks current inductively induced in the substrate by the conductors.
