  • Publication number: 20150243489
    Abstract: A Ti-containing remaining in a chamber of a plasma processing apparatus can be simply and efficiently removed. In a Low-k film etching process, immediately after a dry etching process (process S2) is finished, a dry cleaning process is performed in the presence of a wafer while the wafer is held on an electrostatic chuck 40 (process S3). The dry cleaning process (process S3) is performed to mainly remove the Ti-containing reactant remaining in the chamber 10. To this end, a cleaning gas containing a H2 gas and a N2 gas is introduced into the chamber 10 from a processing gas supply unit 70 at a preset flow rate ratio. Then, a first high frequency power HF for plasma generation is applied to a susceptor 12 at a preset power level, so that plasma is generated within the chamber 10 by the high frequency discharge of the cleaning gas.

  • Patent number: 7906219
    Abstract: A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate.

  • Patent number: 7488689
    Abstract: In a vacuum processing chamber, an etching is performed on an object to be processed having at least a mask layer formed in a predetermined pattern and a Ti layer, as a layer to be etched, formed under the mask layer. During the etching, a first plasma processing is carried out to etch the Ti layer by using a plasma of an etching gas containing a fluorine compound at an inner pressure of the chamber of 4 Pa or less. Subsequently, a second plasma processing for dry cleaning is performed by using a plasma of a cleaning gas after the first plasma processing is completed. At this time, a deposit containing a Ti compound produced during the plasma processing is removed.

  • Publication number: 20070163995
    Abstract: In etching an insulating film such as an SiOC film or the like, in order to suppress a diameter of a hole or a width of a groove, a pre-processing is performed before performing the etching. In the pre-processing, a processing gas containing CF4 gas and CH3F gas is converted into a plasma, and an opening size of an opening portion of a resist mask is decreased by depositing deposits at a sidewall thereof by using the plasma. Further, in etching the SiOC film, a processing gas containing CF4 gas, CH3F gas, and N2 gas is converted into a plasma by supplying a processing gas atmosphere by using a first high frequency wave for generating the plasma, wherein the electric power divided by a surface area of a substrate becomes over 1500 W/70685.8 mm2 (a surface area of a 300 mm wafer), and then the SiOC film is etched.
