Abstract:
The present disclosure relates to a semiconductor device and a manufacturing method, and more particularly to forming via rail and deep via structures to reduce parasitic capacitances in standard cell structures. Via rail structures are formed in a level different from the conductive lines. The via rail structure can reduce the number of conductive lines and provide larger separations between conductive lines that are on the same interconnect level and thus reduce parasitic capacitance between conductive lines.

Claim (Index 1):
A semiconductor structure comprising:\n a plurality of gate structures; a plurality of vias formed in a first dielectric layer, wherein each via of the plurality of vias is formed on each gate structure of the plurality of gate structures; a conductive rail structure formed in the first dielectric layer and over at least one via of the plurality of vias, wherein the conductive rail structure is electrically connected to the at least one via of the plurality of vias; a second dielectric layer formed over the first dielectric layer and the conductive rail structure; a deep via formed at least in the second dielectric layer and over the conductive rail structure, wherein the deep via is electrically connected to the conductive rail structure; and a first plurality of metal lines formed over and electrically connected to the deep via.
