Abstract:
Methods are disclosed herein that improve contours of trenches formed when fabricating vias and conductive lines of a multi-layer interconnect (MLI) structure. An exemplary device that can result from such methods includes a via of an MLI structure and a conductive line of the MLI structure disposed over the via. A first dielectric liner layer is disposed along sidewalls of the via and sidewalls of the conductive line. A thickness of the first dielectric liner layer is substantially the same along the sidewalls of the via. A thickness of the first dielectric liner layer increases along the sidewalls of the conductive line, such that the first dielectric liner layer has a tiger-tooth shape at each bottom corner of the conductive line. A second dielectric liner layer is disposed along the first dielectric liner layer that is disposed along the sidewalls of the via.

Claim (Index 19):
The device of  claim 17 , wherein the first dielectric capping layer and the second dielectric capping layer each include a non-carbon-containing dielectric material.
