    摘要: A semiconductor structure including a highly reliable high aspect ratio contact structure in which key-hole seam formation is eliminated is provided. The key-hole seam formation is eliminated in the present invention by providing a densified noble metal-containing liner within a high aspect ratio contact opening that is present in a dielectric material. The densified noble metal-containing liner is located atop a diffusion barrier and both those elements separate the conductive material of the inventive contact structure from a conductive material of an underlying semiconductor structure. The densified noble metal-containing liner of the present invention is formed by deposition of a noble metal-containing material having a first resistivity and subjecting the deposited noble metal-containing material to a densification treatment process (either thermal or plasma) that decreases the resistivity of the deposited noble metal-containing material to a lower resistivity.

    摘要: A semiconductor structure is provided that includes an interconnect structure and a fuse structure located in different areas, yet within the same interconnect level. The interconnect structure has high electromigration resistance, while the fuse structure has a lower electromigration resistance as compared with the interconnect structure. The fuse structure includes a conductive material embedded within an interconnect dielectric in which the upper surface of the conductive material has a high concentration of oxygen present therein. A dielectric capping layer is located atop the dielectric material and the conductive material. The presence of the surface oxide layer at the interface between the conductive material and the dielectric capping layer degrades the adhesion between the conductive material and the dielectric capping layer. As such, when current is provided to the fuse structure electromigration of the conductive material occurs and over time an opening is formed in the conductive material blowing the fuse element.
