  • Patent number: 9816193
    Abstract: Methods, systems, and apparatus for plating a metal onto a work piece with a plating solution having a low oxygen concentration are described. In one aspect, a method includes reducing an oxygen concentration of a plating solution. The plating solution includes about 100 parts per million or less of an accelerator. After reducing the oxygen concentration of the plating solution, a wafer substrate is contacted with the plating solution in a plating cell. The oxygen concentration of the plating solution in the plating cell is about 1 part per million or less. A metal is electroplated with the plating solution onto the wafer substrate in the plating cell. After electroplating the metal onto the wafer substrate, an oxidizing strength of the plating solution is increased.

  • Patent number: 7678713
    Abstract: The present invention provides a process for improving the hardness and/or modulus of elasticity of a dielectric layer and a method for manufacturing an integrated circuit. The process for improving the hardness and/or modulus of elasticity of a dielectric layer, among other steps, includes providing a dielectric layer having a hardness and a modulus of elasticity, and subjecting the dielectric layer to an energy beam, thereby causing the hardness or modulus of elasticity to increase in value.

  • Publication number: 20050090087
    Abstract: A process for forming nickel silicide and silicon nitride structure in a semiconductor integrated circuit device is described. Good adhesion between the nickel silicide and the silicon nitride is accomplished by passivating the nickel silicide surface with nitrogen. The passivation may be performed by treating the nickel silicide surface with plasma activated nitrogen species. An alternative passivation method is to cover the nickel silicide with a film of metal nitride and heat the substrate to about 500° C. Another alternative method is to sputter deposit silicon nitride on top of nickel silicide.

  • Patent number: 6872665
    Abstract: A dual damascene process flow for forming interconnect lines and vias in which at least part of the via (116) is etched prior to the trench etch. A low-k material such as a thermoset organic polymer is used for the ILD (106) and IMD (110). After the at least partial via etch, a BARC (120) is deposited over the structure including in the via (116). Then, the trench (126) is patterned and etched. Although at least some of the BARC (120) material is removed during the trench etch, the bottom of the via (116) is protected.
