  • Patent number: 10083830
    Abstract: It was found out that when radicals generated by plasma are fed to a treatment chamber via a plurality of holes (111) formed on a partition plate which separates a plasma-forming chamber (108) from the treatment chamber, and the radicals are mixed with a treatment gas which is separately fed to the treatment chamber, the excitation energy of the radicals is suppressed and thereby the substrate surface treatment at high Si-selectivity becomes possible, which makes it possible to conduct the surface treatment of removing native oxide film and organic matter without deteriorating the flatness of the substrate surface. The radicals in the plasma are fed to the treatment chamber via radical-passing holes (111) of a plasma-confinement electrode plate (110) for plasma separation, the treatment gas is fed to the treatment chamber (121) to be mixed with the radicals in the treatment chamber, and then the substrate surface is cleaned by the mixed atmosphere of the radicals and the treatment gas.

  • Patent number: 8524094
    Abstract: The object of the present invention is to provide a masking material for dry etching, which is suitable for fine processing of a magnetic film as thin as a few nm such as NiFe or CoFe constituting a TMR film and capable of simplifying the process for producing a TMR element and reducing production costs related to facilities and materials. This object was solved by a masking material for dry etching of a magnetic material by using a mixed gas of carbon monoxide and a nitrogenous compound as etching gas, which comprises a metal (tantalum, tungsten, zirconium or hafnium) with a melting or boiling point increasing upon conversion thereof into a nitride or carbide.

  • Publication number: 20120258582
    Abstract: In one embodiment of the present invention, the processing surface of a substrate having at least a single crystal surface and a dielectric surface is exposed to a first deposition gas containing a source gas and a doping gas to form a first doped thin film on the single crystal surface, whereas supply of the first deposition gas is stopped before a film is formed on the dielectric surface. Next, the processing surface of the substrate is exposed to a second deposition gas containing a source gas and a doping gas to form a second thin film doped with less dopant than the first thin film on the single crystal surface, whereas supply of the second deposition gas is stopped before a film is formed on the dielectric surface. Subsequently, the processing surface of the substrate is exposed to a chlorine-containing gas to be etched.

  • Publication number: 20110312179
    Abstract: The present invention provides a substrate processing method and a substrate processing apparatus, which are capable of forming a high-k dielectric film with few trapping levels due to oxygen deficiencies and hot carriers by a sputtering method in one and the same vacuum vessel. The substrate processing method according to a first embodiment of the present invention includes: a first step of heating a to-be-processed substrate (102) arranged in a film forming treatment chamber (100) and depositing a metal film on the to-be-processed substrate (102) by physical vapor deposition using a target (106); and a second step of supplying a gas containing elements for oxidizing a metal film in the film forming treatment chamber (100) to oxidize the metal film by a thermal oxidation reaction.

  • Publication number: 20100326818
    Abstract: The invention provides a method of manufacturing a semiconductor device and a sputtering apparatus which improve the composition of a film formed by a metal and a reactive gas without increasing the number of steps. An embodiment includes the steps of: placing a substrate on a substrate holder in a process chamber; and sputtering a target in the process chamber by applying electric power thereto while feeding a first reactive gas and a second reactive gas having higher reactivity than that of the first reactive gas into the process chamber, to form a film containing a target material on the substrate. The step of forming a film is conducted by feeding at least the first reactive gas from a first gas feed opening formed near the target, and by feeding the second reactive gas from a second gas feed opening formed at a position with the distance from the target larger than that of the first gas feed opening.

  • Publication number: 20100221895
    Abstract: HF-originated radicals generated in a plasma-forming chamber are fed to a treatment chamber via feed holes, while HF gas molecules as the treatment gas are supplied to the treatment chamber from near the radical feed holes to suppress the excitation energy, thereby increasing the selectivity to Si to remove a native oxide film. Even with the dry-treatment, the surface treatment provides good surface flatness equivalent to that obtained by the wet-cleaning which requires high-temperature treatment, and further attains growth of Si single crystal film on the substrate after the surface treatment. The surface of formed Si single crystal film has small quantity of impurities of oxygen, carbon, and the like. After sputtering Hf and the like onto the surface of the grown Si single crystal film, oxidation and nitrification are applied thereto to form a dielectric insulation film such as HfO thereon, thus forming a metal electrode film.
