  • 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.

  • 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.

  • Patent number: 7807585
    Abstract: A dielectric insulating film including HfO or the like is formed by: cleaning a surface of a semiconductor substrate by exposing the substrate surface to a fluorine radical; performing hydrogen termination processing with a fluorine radical or a hydride (SiH4 or the like); sputtering Hf or the like; and then performing oxidation/nitridation. These steps are carried out without exposing the substrate to atmosphere, thereby making it possible to obtain a C-V curve with less hysteresis and realize a MOS-FET having favorable device characteristics.

  • 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.
