ABSTRACT:
An etching processing method capable of etching a low dielectric constant layer at a reduced cost by using an etching processing apparatus comprising a vacuum vessel, a sample loading electrode disposed in the vacuum vessel, a gas introduction device for introducing a reaction gas into the vacuum vessel, an antenna for forming plasmas in the vacuum vessel, and a high frequency power supply for supplying a bias power to a sample loaded on the sample loading electrode, wherein the bias power to be supplied to the sample is 3 W/cm2or less, and the gas introduction device introduces a gas containing chlorine atoms or bromine atoms to apply etching processing to an inorganic insulation material of low dielectric constant loaded on the loading electrode.
