    摘要: A semiconductor interconnect structure including a semiconductor substrate, a semiconductor active device formed in the substrate, a layer of low-k dielectric material, a first patterned conducting layer, a second patterned conducting layer, and a cap layer formed thereon. The low-k material layer is formed over the semiconductor device. The first conducting line is formed in the low-k material layer and connected to the semiconductor active device. The second conducting line is formed in the low-k material layer but not electrically connected to the semiconductor active device. The cap layer is formed over the low-k material layer, the first and second conducting lines. The cap layer includes silicon and carbon. Since the adhesion strength between the cap layer and the patterned conducting layer is greater than the adhesion strength between the cap layer and the low-k material layer, the addition of second patterned conducting layer would eliminate the overall possibility of delamination between the surface where cap layer is in contact with the low-k material and the first and the second patterned conducting layers.

    摘要: The present disclosure provides a method of fabricating a semiconductor device, a semiconductor device fabricated by such a method, and a chemical mechanical polishing (CMP) tool for performing such a method. In one embodiment, a method of fabricating a semiconductor device includes providing an integrated circuit (IC) wafer including a metal conductor in a trench of a dielectric layer over a substrate, and performing a chemical mechanical polishing (CMP) process to planarize the metal conductor and the dielectric layer. The method further includes cleaning the planarized metal conductor and dielectric layer to remove residue from the CMP process, rinsing the cleaned metal conductor and dielectric layer with an alcohol, and drying the rinsed metal conductor and dielectric layer in an inert gas environment.
