  • Patent number: 6939808
    Abstract: A method for etching a metal layer formed on a substrate to form a metal line, using an amorphous carbon layer as a pattern mask. One embodiment of the method of the invention etches a metal layer formed on a substrate, for forming a metal line, by depositing an amorphous carbon layer on the metal layer, patterning the amorphous carbon layer to provide a pattern mask on the metal layer, thus exposing portions of said metal layer; and etching the exposed portions of the metal layer, to form a metal line. In an embodiment, the metal layer comprises a copper layer.

  • Patent number: 6423384
    Abstract: The present invention generally provides a method for depositing a low dielectric constant amorphous carbon film on a substrate or other workpiece using high density plasma chemical vapor deposition (HDP-CVD) techniques. Specifically, the present invention provides a method for forming an amorphous carbon film having a low dielectric constant of less than about 3.0 and a high thermal stability at a temperature of at least about 400° C. In a preferred embodiment, the film is deposited using methane (CH4) and argon in a HDP-CVD reactor. The amorphous carbon film formed according to the invention is useful for many applications in ultra large scale integration (ULSI) structures and devices, such as for example, an inter-metal dielectric material and an anti-reflective coating useful for patterning sub-micron interconnect features.

  • Patent number: 6395157
    Abstract: A method and apparatus for conditioning a surface of a ceramic body in a process chamber when the process chamber has a vacuum pump, an anode and a cathode. The conditioning method consists of pumping the process chamber down to a vacuum with the vacuum pump, introducing a gas into the chamber, energizing the anode and cathode with RF power to ignite the gas into a plasma, sputter etchinq the surface with ions from the plasma to remove contaminants therefrom. The method is accomplished either within a process chamber to condition, in situ, a ceramic chuck or within a cleaning chamber to condition any form of ceramic body or component.

  • Patent number: 6211065
    Abstract: The present invention provides a method of depositing an amorphous fluorocarbon film using a high bias power applied to the substrate on which the material is deposited. The invention contemplates flowing a carbon precursor at rate and at a power level so that equal same molar ratios of a carbon source is available to bind the fragmented fluorine in the film thereby improving film quality while also enabling improved gap fill performance. The invention further provides for improved adhesion of the amorphous fluorocarbon film to metal surfaces by first depositing a metal or TiN adhesion layer on the metal surfaces and then stuffing the surface of the deposited adhesion layer with nitrogen. Adhesion is further improved by coating the chamber walls with silicon nitride or silicon oxynitride.
