Abstract: A slurry dispensing apparatus for use with a chemical mechanical polishing tool for planarizing semiconductor substrates having irregular topology. The apparatus includes a slurry dispensing manifold with a first end suspended over a polishing pad, and a second end for mounting to the chemical mechanical polishing tool. The slurry dispensing manifold has a linear array of nozzles positioned under the suspended manifold. Each nozzle provides an adjusted slurry mixture that is supplied from bifurcated supply lines. A first branch supplying a slurry, and a second branch supplying deionized water. Each nozzle is capable of providing a particular slurry concentration to either decrease or to increase polishing rate in specific zonal areas on a substrate according to its surface topology.

Abstract: A new method to monitor sheet resistance of a metal silicide layer in the manufacture of an integrated circuit device is achieved. The method comprises providing a metal silicide layer overlying an exposed silicon layer on a substrate. A thermal wave intensity signal is generated for the metal silicide layer by an optical measurement system. The optical measurement system comprises a first laser beam that is intensity modulated and a second laser beam. The first and second laser beams comprise different wavelengths. A dichroic mirror is used to combine the first and second laser beams and to project the first and second laser beams onto the metal silicide layer. A detector is used to gather the second laser beam reflected from the metal silicide layer and to generate a thermal wave intensity signal based on the reflected second laser beam. Sheet resistance of the metal silicide layer is calculated by a linear equation based on the thermal wave intensity signal.

Abstract: A new method is provided for the creation of an adhesion/barrier layer over which a tungsten interconnect is created. The invention reduces metal extrusion and effects of pin-holes by dividing the process of barrier material of TiN deposition into phases, whereby after about half the thickness of the required layer of TiN has been deposited, an intermediate and very thin layer of Ti is deposited. After the thin layer of Ti has been deposited, the deposition of the barrier layer of TiN is continued to the point where the required thickness for the layer of TiN has been reached.
