  • Patent number: 7488688
    Abstract: A method for removing an oxide layer such as a natural oxide layer and a semiconductor manufacturing apparatus which uses the method to remove the oxide layer. A vertically movable susceptor is installed at the lower portion in a processing chamber and a silicon wafer is loaded onto the susceptor when it is at the lower portion of the processing chamber. The air is exhausted from the processing chamber to form a vacuum condition therein. A hydrogen gas in a plasma state and a fluorine-containing gas are supplied into the processing chamber to induce a chemical reaction with the oxide layer on the silicon wafer, resulting in a reaction layer. Then, the susceptor is moved up to the upper portion of the processing chamber, to anneal the silicon wafer on the susceptor with a heater installed at the upper portion of the processing chamber, thus vaporizing the reaction layer. The vaporized reaction layer is exhausted out of the chamber.

  • Patent number: 7446033
    Abstract: A metal interconnection of a semiconductor device, formed using a damascene process, has large grains and yet a smooth surface. First, a barrier layer and a metal layer are sequentially formed in an opening in an interlayer dielectric layer. A CMP process is carried out on the metal layer to form a metal interconnection remaining within the opening. Then, the metal interconnection is treated with plasma. The plasma treatment creates compressive stress in the metal interconnection, which stress produces hillocks at the surface of the metal interconnection. In addition, the plasma treatment process causes grains of the metal to grow, especially when the design rule is small, to thereby decrease the resistivity of the metal interconnection. The hillocks are then removed by a CMP process aimed at polishing the portion of the barrier layer that extends over the upper surface of the interlayer dielectric layer. Finally, a capping insulating layer is formed.

  • Publication number: 20040217013
    Abstract: The present invention relates to an apparatus and method for electropolishing a metal wire layer on a semiconductor device. To electropolish the metal wiring layer, a wafer is dipped into an electrolyte solution, and positive and negative voltages are applied to the wafer and electrodes, respectively. The electrodes include a main electrode and a plurality of auxiliary electrodes disposed above the main electrode. In a preferred embodiment, the plurality of auxiliary electrodes are mesh-type electrodes and are annular in shape and concentrically disposed, and thus the electrolyte solution can readily flow between them. Further, the metal wiring layer is preferably sequentially electropolished outwardly from the center of the wafer by sequentially applying negative voltages to the plurality of annular auxiliary electrodes. In this manner, a uniform electropolishing process is performed.
