    Abstract: A method for repairing process-related damage of a dielectric film includes: (i) adsorbing a first gas containing silicon on a surface of the damaged dielectric film without depositing a film in the absence of reactive species, (ii) adsorbing a second gas containing silicon on a surface of the dielectric film, followed by applying reactive species to the surface of the dielectric film, to form a monolayer film thereon, and (iii) repeating step (ii). The duration of exposing the surface to the first gas in step (i) is longer than the duration of exposing the surface to the second gas in step (ii).

  • Patent number: 7662696
    Abstract: According to the present invention, an oxide film with the film quality almost equivalent to that of the thermal oxide can be formed by the low-temperature treatment. After removing an insulator on the active region of the substrate which constitutes a semiconductor wafer, an insulator made of, for example, silicon oxide is deposited on the main surface of the semiconductor wafer by the low pressure CVD method. This insulator is a film to form a gate insulator of MISFET in a later step. Subsequently, a plasma treatment is performed in an atmosphere containing oxygen (oxygen plasma treatment) to the insulator in the manner as schematically shown by the arrows. By so doing, the film quality of the insulator formed by the CVD method can be improved to the extent almost equivalent to that of the insulator formed of the thermal oxide.

  • Patent number: 7262101
    Abstract: A method of manufacturing a semiconductor integrated circuit device comprising forming a silicon oxide film as thin as 5 nm or less on the surfaces of p type wells and n type wells by wet oxidizing a substrate, heating the substrate in an atmosphere containing about 5% of an NO gas to introduce nitrogen into the silicon oxide film so as to form a silicon oxynitride film, exposing the substrate to a nitrogen plasma atmosphere to further introduce nitrogen into the silicon oxynitride film in order to form a silicon oxynitride gate insulating film having a first peak concentration near the interface with the substrate and a second peak concentration near the surface thereof. Thereby, the concentration of nitrogen in the gate insulating film is increased without raising the concentration of nitrogen near the interface between the substrate and the gate insulating film to a higher level than required.
