Abstract
A method of post-treating a silicon nitride (SiN)-based dielectric film formed on a surface of a substrate includes positioning a substrate having a silicon nitride (SiN)-based dielectric film formed thereon in a processing chamber, and exposing the silicon nitride (SiN)-based dielectric film to helium-containing high-energy low-dose plasma in the processing chamber. Energy of helium ions in the helium-containing high-energy low-dose plasma is between 1 eV and 3.01 eV, and flux density of the helium ions in the helium-containing high-energy low-dose plasma is between 5×10ions/cm·sec and 1.37×10ions/cm·sec.
