Method and apparatus for generating gas plasma, gas composition for generating plasma and method for manufacturing semiconductor device using the same

摘要

A method and an apparatus for generating a plasma, and a method and an apparatus for manufacturing a semiconductor device using the plasma. A gas flows along a flow path having the displacement identical to the lines of magnetic force of the main magnetic field, and high frequency alternating current is applied to the gas, thereby generating a gas plasma. The gas plasma is provided into a processing chamber to perform a process for manufacturing the semiconductor device.
