Structure of power grid for semiconductor devices and method of making the same

Abstract:

An embodiment of the invention provides a semiconductor structure, which may include a stud of a first conductive material formed inside a dielectric layer; a via of a second conductive material having a bottom and sidewalls with the bottom and the sidewalls being covered by a conductive liner, and the bottom being formed directly on top of the stud and being in contact with the via through the conductive liner; and one or more conductive paths of a third conductive material connecting to the via through the conductive liner at the sidewalls of said the. A method of making the semiconductor structure is also provided.
