The present invention provides a reactive gas application apparatus capable of easily and surely applying a reactive gas to a target object. The reactive gas application apparatus () includes: a plasma generating unit (), a nozzle () for discharging a reactive gas activated by plasma generated in the plasma generation unit (), and a light source unit () for emitting light toward a position ahead of a tip of the nozzle (). The reactive gas application apparatus preferably further includes a control unit for synchronizing plasma generation in the plasma generation unit and light emission in the light source unit.

Reactive gas application apparatus

The present invention discloses a medical therapeutic apparatus () which generates plasma and blows out an reactive gas generated by the generated plasma toward a target object from an outlet, wherein a temperature of the reactive gas at a target surface positioned at a distance of 1 mm or more and 10 mm or less from the outlet is 40&#xb0; C. or less, and a radical concentration is 0.1 to 300 &#x3bc;mol/L as determined by a hydroxy radical concentration measuring method comprising applying the reactive gas to 0.4 mL of a 0.2 mol/L solution of DMPO (5,5-dimethyl-1-pyrroline-N-oxide) for 30 seconds with a distance from the outlet to a liquid surface of the solution being 5.0 mm, and measuring a hydroxyl radical concentration of the resulting solution by electron spin resonance (ESR) method.

Uniform oxynitride and nitride films can be formed by low-temperature and high-speed nitriding reaction not dependent on the nitriding time or nitriding temperature. A solid dielectric is provided on at least one of opposed surfaces of a pair of electrodes opposed to each other under a pressure of 300 (Torr) or higher, a nitrogen gas containing an oxide equal to or lower than 0.2% is introduced into a space between the pair of opposed electrodes, an electric field is applied to the nitrogen gas, and the resulting N(2p.s.) or N(H.I.R) active species is brought into contact with an object to be processed to form an oxynitride film/nitride film on a surface of the object to be processed.
