Abstract: PROBLEM TO BE SOLVED: To improve an etching rate, improve the selectivity and reduce the damage to the inside of a reaction chamber by a method wherein a high frequency voltage is applied to a member which couples with fluorine to reduce the fluorine monomer in a treatment chamber. SOLUTION: Fluorine (F) radical reducing members 12, for instance Si members, are placed on the walls of a reaction chamber 3b by F-radical reducing member supporters 13 and a high frequency voltage is applied to the F- radical reducing members 12 by a high frequency power supply 11b. F-radicals in the reaction chamber 3b adhere to the F-radical reducing members 12 to produce low reactivity gas which is exhausted through a gas exhaust system 8. However, SiFx which is produced by the reaction between the F-radicals in a vapor phase and the F-radical reducing member material (in this case, Si) exists on the surface of the F-radical reducing member 12. Then, the deposit is removed by sputtering which is caused by ion collision induced by applying the high frequency voltage to the F-radical reducing members 12 to expose Si on the surface of the F-radical reducing members 12. Thus, the reaction between the F-radical reducing members 12 and F-radicals is further promoted.
