Method for etching organic film |
| abstract |
Disclosed is a method for etching an organic film. Plasma of a processing gas containing hydrogen gas and nitrogen gas is generated within a processing container of a plasma processing apparatus that accommodates a workpiece. A partial region of the organic film that is exposed from a hard mask is changed into a denatured region by the generation of the plasma of the processing gas. Subsequently, plasma of a rare gas is generated within the processing container. The denatured region is removed by the plasma of the rare gas, and a substance released from the denatured region is deposited on the surface of the hard mask. In this method, the generation of the plasma of the processing gas and the generation of the plasma of the rare gas are repeated alternately. |
