Provided are methods post deposition treatment of films comprising SiN. Certain methods pertain to providing a film comprising SiN; and exposing the film to an inductively coupled plasma, capacitively coupled plasma or a microwave plasma to provide a treated film with a modulated film stress and/or wet etch rate in dilute HF. Certain other methods comprise depositing a PEALD SiN film followed by exposure to a plasma nitridation process or a UV treatment to provide a treated film. |
