Dry etching - Wikipedia

Dry etching refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a boardment of ions (usually a plasma of reactive gases such as fluorocarbons, oxygen, chlorine, boron trichloride; sometimes with addition of nitrogen, argon, helium and other gases) that dislodge portions of the material from the exposed surface.
