  • Publication number: 20090170309
    Abstract: A barrier architecture is provided that includes different materials that are selected to be employed in connection with copper contact applications. Some of the barrier material is formed over trench contact sidewalls, and other different barrier material is formed over trench contact bottoms. By selecting the appropriate barrier materials, electromigration can be improved while, at the same time, interconnect and contact resistances can be kept low and array leakage can be mitigated.

  • Patent number: 7371311
    Abstract: An embodiment of the invention provides a method for reducing within die thickness variations by modifying the concentration of components of a low-acid electroplating solution. For one embodiment, the leveler concentration is increased sufficiently to reduce within die thickness variations to a specified value. For one embodiment of the invention, the leveler and suppressor are increased to reduce within die thickness variations and substantially reduce a plurality of electroplating defects. In such an embodiment the combined concentration of leveler and suppressor is determined to maintain adequate gap fill.

  • Publication number: 20060091018
    Abstract: Embodiments of the invention provide methods for electroplating a substrate that substantially reduce or eliminate protrusions and decrease WID thickness variations. The number of protrusions formed on the plating surface is highly dependent upon the electroplating current density. Embodiments of the invention vary the electroplating current waveform by implementing an initial current step sufficient to fill substrate features and a terminal current step sufficient to achieve the specified plating thickness while suppressing protrusions and within die thickness variations.

  • Publication number: 20060006071
    Abstract: Embodiments of the invention provide methods of reducing electroplating defects by adjusting immersion conditions. For one embodiment, the immersion conditions are adjusted based upon characteristics of the substrate, including feature size. Additionally or alternatively, the immersion conditions may be adjusted based upon aspects of the electroplating process, including motion of the substrate upon immersion. Immersion conditions that may be adjusted in accordance with various embodiments of the invention include entry bias voltage/current, vertical immersion speed, and angle of immersion.
