  • Patent number: 7223442
    Abstract: The present invention provides a method for producing a conducting doped diamond-like nanocomposite film containing, as basic elements, carbon, silicon, metal, oxygen and hydrogen. The film is produced as follows: a substrate is disposed in a vacuum chamber, and a voltage of 0.3-5.0 kV is applied to the substrate; a gas discharge plasma with an energy density of more than 5 kilowatt-hour/gram-atom of carbon particles is generated, and an organosiloxane compound is evaporated into the plasma; a beam of particles of a dopant is introduced into the plasma; and a film is grown on the substrate to produce a conducting doped carbon nanocomposite film with a predetermined relationship of atomic concentrations of carbon, metal and silicon. The film surface is coated with a silicon dioxide layer. A unidirectional alternating current is passed through the film in a current generator mode to effect electric thermal exposure of the film.

  • Patent number: 7182980
    Abstract: Annular substrates (20) are stacked in an enclosure where they define an inside volume (24) and an outer volume (26) outside the stack. A gas containing at least one precursor of a matrix material to be deposited within the pores of the substrates is channeled inside the enclosure to a first one (24) of the two volumes, and a residual gas is extracted from the enclosure from the other one (26) of the volumes. One or more leakage passages (22) allow the volumes to communicate with each other, other than through the substrates. The total section of the leakage passages has a value lying between a minimum value for ensuring that a maximum gas pressure in the first volume is not exceeded until the end of densification, and a maximum value such that a pressure difference is indeed established between the two volumes from the beginning of densification.

  • Patent number: 7147896
    Abstract: An electroless nickel plating method for the preparation of zirconia ceramic material. The surface of the zirconia ceramic material is first cleaned of contaminants. This is followed by an etching step where the surface of the material is etched by an acid. Then, activating the surface of the material is achieved by first applying a tin sensitizer, and then a palladium activator. Following the palladium activator step, applying an electroless nickel to the surface of the post activated material. After the electroless nickel bath, the zirconial ceramic material can then be further electroless or electrolytically plated with a variety of finishes. Applying the method of the present invention provides a suitable, commercially practicable method for the preparation of zirconia ceramic material for electroless nickel plating, so that the electroless nickel chemistry is distributed evenly on the material's surface.

  • Patent number: 7118783
    Abstract: CVD, ALD, and other vapor processes used in processing semiconductor workpieces often require volatilizing a liquid or solid precursor. Certain embodiments of the invention provide improved and/or more consistent volatilization rates by moving a reaction vessel. In one exemplary embodiment, a reaction vessel is rotated about a rotation axis which is disposed at an angle with respect to vertical. This deposits a quantity of the reaction precursor on an interior surface of the vessel's sidewall which is exposed to the headspace as the vessel rotates. Other embodiments employ drivers adapted to move the reaction vessel in other manners, such as a pendulum arm to oscillate the vessel along an arcuate path or a mechanical linkage which moves the vessel along an elliptical path.

  • Patent number: 7118779
    Abstract: Protective layers are formed on a surface of an atomic layer deposition (ALD) or chemical vapor deposition (CVD) reactor. Parts defining a reaction space for an ALD or CVD reactor can be treated, in situ or ex situ, with chemicals that deactivate reactive sites on the reaction space surface(s). A pre-treatment step can maximize the available reactive sites prior to the treatment step. With reactive sites deactivated by adsorbed treatment reactant, during subsequent processing the reactant gases have reduced reactivity or deposition upon these treated surfaces. Accordingly, purge steps can be greatly shortened and a greater number of runs can be conducted between cleaning steps to remove built-up deposition on the reactor walls.

  • Patent number: 7041335
    Abstract: Methods and apparatus of forming titanium tantalum silicon nitride (TixTay(Si)Nz) layers are described. The titanium tantalum silicon nitride (TixTay(Si)Nz) layer may be formed using a cyclical deposition process by alternately adsorbing a titanium-containing precursor, a tantalum-containing precursor, a nitrogen-containing gas and a silicon-containing gas on a substrate. The titanium-containing precursor, the tantalum-containing precursor, the silicon-containing precursor and the nitrogen-containing precursor react to form the titanium tantalum silicon nitride (TixTay(Si)Nz) layer on the substrate. The formation of the titanium tantalum silicon nitride (TixTay(Si)Nz) layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the titanium tantalum silicon nitride (TixTay(Si)Nz) layer is used as a diffusion barrier for a copper metallization process.

  • Patent number: 7041341
    Abstract: The present invention is related to methods and apparatus for processing weak ferroelectric films on semiconductor substrates, including relatively large substrates, e.g., with 300 millimeter diameter. A ferroelectric film of zinc oxide (ZnO) doped with lithium (Li) and/or magnesium (Mg) is deposited on a substrate in a plasma assisted chemical vapor deposition process such as an electron cyclotron resonance chemical vapor deposition (ECR CVD) process. Zinc is introduced to a chamber through a zinc precursor in a vaporizer. Microwave energy ionizes zinc and oxygen in the chamber to a plasma, which is directed to the substrate with a relatively strong field. Electrically biased control grids control a rate of deposition of the plasma. The control grids also provide Li and/or Mg dopants for the ZnO to create the ferroelectric film. A desired ferroelectric property of the ferroelectric film can be tailored by selecting an appropriate composition of the control grids.
