  • Patent number: 8117987
    Abstract: Methods and apparatus for hot wire chemical vapor deposition (HWCVD) are provided herein. In some embodiments, an inline HWCVD tool may include a linear conveyor for moving a substrate through the linear process tool; and a multiplicity of HWCVD sources, the multiplicity of HWCVD sources being positioned parallel to and spaced apart from the linear conveyor and configured to deposit material on the surface of the substrate as the substrate moves along the linear conveyor; wherein the substrate is coated by the multiplicity of HWCVD sources without breaking vacuum. In some embodiments, methods of coating substrates may include depositing a first material from an HWCVD source on a substrate moving through a first deposition chamber; moving the substrate from the first deposition chamber to a second deposition chamber; and depositing a second material from a second HWCVD source on the substrate moving through the second deposition chamber.

  • Patent number: 8101025
    Abstract: A method for controlling corrosion of a substrate is provided herein. In one embodiment, a method for controlling corrosion of a substrate includes the steps of providing a substrate having a patterned photoresist layer with a metallic residue disposed thereon; exposing the substrate to a hydrogen-based plasma to remove the metallic residue; and removing the photoresist. The metallic residue may comprise residue from etching at least one of aluminum or copper. The metallic residue may further comprise a halogen compound from etching a metal-containing layer with a halogen-based process gas. The hydrogen-based plasma may comprise hydrogen (H2) and may further comprise at least one of nitrogen (N2) and water (H2O) vapor. The hydrogen-based plasma may further comprise an inert gas, such as argon (Ar).

  • Patent number: 8089046
    Abstract: A method for determining the flow rate of a gas includes measuring a first concentration of a calibration gas provided to the process chamber at a first pressure and temperature by directing infrared radiation into the process chamber and monitoring a first amount of infrared radiation absorbed by the calibration gas. A mixture of a second gas and the calibration gas is provided to the process chamber while maintaining the first pressure and temperature. A second concentration of the calibration gas in the mixture is measured by directing infrared radiation into the process chamber and monitoring a second amount of infrared radiation absorbed by the calibration gas. A flow rate of the second gas is calculated by comparing the first and second concentrations of the calibration gas. In one embodiment, the calibration gas and the second gas may not absorb the infrared radiation at the same wavelength.

  • Patent number: 8050440
    Abstract: A hearing aid (2) is provided which includes a receiver tube (14) containing waterproof ear wax mesh trap (16). The receiver tube is removably connected directly to the hearing aid receiver (12) and the tube may be cleaned or replaced by a hearing aid dispenser or audiologist during a patient office visit. The receiver tube includes a waterproof ear wax trap lodged within, that is made of a foamed and stretched PTFE membrane. Further, the length of the receiver tube may be adjusted by the dispenser or audiologist during the office visit by clipping it accordingly.
