Abstract:
Integrated circuits, a process for recessing an embedded copper feature within a substrate, and a process for recessing an embedded copper interconnect within an interlayer dielectric substrate of an integrated circuit are provided. In an embodiment, a process for recessing an embedded copper feature, such as an embedded copper interconnect, within a substrate, such as an interlayer dielectric substrate, includes providing a substrate having an embedded copper feature disposed therein. The embedded copper feature has an exposed surface and the substrate has a substrate surface adjacent to the exposed surface of the embedded copper feature. The exposed surface of the embedded copper feature is nitrided to form a layer of copper nitride in the embedded copper feature. Copper nitride is selectively etched from the embedded copper feature to recess the embedded copper feature within the substrate.
