    Abstract: The present invention relates generally to an improved apparatus and process to provide a thin self-aligning layer prior to forming a conducting film layer thereover to improve the film characteristics and deposition coverage. In one aspect of the invention, a dielectric layer is formed over a conducting or semiconducting layer and etched to form an aperture exposing the underlying conducting or semiconducting layer on the aperture floor. An ultra-thin nucleation layer is then deposited by either vapor deposition or chemical vapor deposition onto the field of the dielectric layer. A CVD metal layer is then deposited onto the structure to achieve selective deposition on the floor of the aperture, while preferably also forming a highly oriented blanket layer on the field. In another aspect of the invention, a thin, self-aligning layer is formed over a barrier layer prior to deposition of a conducting film thereover. It is believed that the self-aligning layer enhances the reflectivity of the films by improving the crystal structure in the resulting film and provides improved electromigration performance by providing crystal orientation. The process is preferably carried out in an integrated processing system that includes both a PVD and CVD processing chamber so that once the substrate is introduced into a vacuum environment, the process occurs without the formation of oxides between the layers.

    Abstract: The present invention relates generally to an improved apparatus and process for providing uniform step coverage on a substrate and planarization of metal layers to form continuous, void-free contacts or vias in sub-half micron aperture width applications. In one aspect of the invention, a dielectric layer is formed over a conducting member. A thin nucleation layer is then deposited onto the dielectric layer prior to etching high aspect ratio apertures through the nucleation and dielectric layers to expose the underlying conducting member on the aperture floor. A CVD metal layer is then deposited onto the structure to achieve selective deposition within the apertures, while preferably also forming a blanket layer on the field. The present apparatus and process reduce the number of steps necessary to fabricate CVD metal interconnects and layers that are substantially void-free and planarized. The metallization process is preferably carried out in an integrated processing system that includes both a PVD and CVD processing chamber so that once the substrate is introduced into a vacuum environment, the metallization of the apertures to form vias and contacts occurs without the formation of oxides between the layers.

    Abstract: Plasma etching or resputtering of a layer of sputtered materials including opaque metal conductor materials may be controlled in a sputter reactor system. In one embodiment, resputtering of a sputter deposited layer is performed after material has been sputtered deposited and while additional material is being sputter deposited onto a substrate. A path positioned within a chamber of the system directs light or other radiation emitted by the plasma to a chamber window or other optical view-port which is protected by a shield against deposition by the conductor material. In one embodiment, the radiation path is folded to reflect plasma light around the chamber shield and through the window to a detector positioned outside the chamber window. Although deposition material may be deposited onto portions of the folded radiation path, in many applications, the deposition material will be sufficiently reflective to permit the emission spectra to be detected by a spectrometer or other suitable detector without significant signal loss. The etching or resputtering may be terminated when the detector detects that an underlying layer has been reached or when some other suitable process point has been reached.

    Abstract: The construction of a film on a wafer, which is placed in a processing chamber, may be carried out through the following steps. A layer of material is deposited on the wafer. Next, the layer of material is annealed. Once the annealing is completed, the material may be oxidized. Alternatively, the material may be exposed to a silicon gas once the annealing is completed. The deposition, annealing, and either oxidation or silicon gas exposure may all be carried out in the same chamber, without need for removing the wafer from the chamber until all three steps are completed. A semiconductor wafer processing chamber for carrying out such an in-situ construction may include a processing chamber, a showerhead, a wafer support and a rf signal means. The showerhead supplies gases into the processing chamber, while the wafer support supports a wafer in the processing chamber. The rf signal means is coupled to the showerhead and the wafer support for providing a first rf signal to the showerhead and a second rf signal to the wafer support.
