    Abstract: Provided is a method of etching a multilayer film including an organic film formed between first and second oxide films. In this method, a high frequency power for generating plasma in etching the organic film is greater than those in etching the first and second oxide films. High frequency bias powers for ion implantation in the etching of the first and second oxide films are greater than that in the etching of the organic film. In the etching of the first and second oxide films and the organic film, a magnetic field is generated such that horizontal magnetic field components in a radial direction with respect to a central axis line of a target object have an intensity distribution having a peak value at a position far from the central axis line, and a position of the peak value in the etching of the organic film is closer to the central axis line than those of the horizontal magnetic field components of the first and second oxide films.

    Abstract: PURPOSE: A substrate processing apparatus is provided to simultaneously prevent charges from being accumulated on a gate electrode and to suppress the quantity of charges passing through a gate oxide layer. CONSTITUTION: A substrate processing apparatus generates an electric field in a processing space between a top electrode and a bottom electrode. The frequency of high frequency power supplied to the bottom electrode is 60 MHz or greater. The substrate processing apparatus processes a substrate mounted on the bottom electrode by using plasma generated by the electric field. The substrate processing apparatus controls the distribution of plasma density by a magnetic field generated by controlling a plurality of electromagnets. The electromagnets are formed on the upper side of a surface which is opposite to the processing space. [Reference numerals] (AA) Ne distribution; (BB) Vdc distribution
