    摘要: A method includes providing at least one wafer having a process layer formed thereon for polishing. The process layer is polished using a first polishing process that is associated with a slurry having a first abrasive particle size. The process layer is polished using a second polishing process that is associated with a slurry having a second abrasive particle size that is different from the first abrasive particle size. A system includes a polishing tool and a process controller. The polishing tool is adapted to receive at least one wafer having a process layer formed thereon for polishing. The polishing tool is adapted to polish the process layer using a first polishing process that is associated with a slurry having a first abrasive particle size. The polishing tool is adapted to polish the process layer using a second polishing process that is associated with a slurry having a second abrasive particle size that is different from the first abrasive particle size. The process controller is coupled to the polishing tool and adapted to communicate with at least one of a slurry controller and the polishing tool.

    摘要: The electromigration resistance of Cu lines is significantly improved by depositing a low-k capping layer thereon, e.g., a silicon carbide capping layer having a dielectric constant of about 4.5 to about 5.5. Embodiments include sequentially treating the exposed planarized surface of inlaid Cu with a plasma containing NH3 diluted with N2, discontinuing the plasma and flow of NH3 and N2, pumping out the chamber; introducing trimethylsilane, NH3 and He, initiating PECVD to deposit the silicon carbide capping layer, as at a thickness of about 200 Å to about 800 Å. Embodiments also include Cu dual damascene structures formed in dielectric material having a dielectric constant (k) less than about 3.9.

    摘要: A test circuit includes a wafer, an insulative layer formed on the wafer, and a plurality of test structures formed in the insulative layer. Each of the test structures comprises a first comb having a first plurality of fingers and a second comb having a second plurality of fingers. The first and second pluralities of fingers are interleaved to define a finger spacing between the first and second pluralities of fingers. The finger spacing in a first one of the test structures being different than the finger spacing in a second one of the test structures. A method for characterizing damage in a semiconductor device includes providing a wafer having an insulative layer and a plurality of test structures formed in the insulative layer. The test structures have different geometries. An electrical characteristic of first and second test structures of the plurality of test structures is determined. The electrical characteristics of the first and second test structures is compared. Damage to the insulative layer is characterized based on the comparison.
