The protective coating may be deposited using particular reactants and/or reaction mechanisms that result in substantially complete sidewall coating at relatively low temperatures without the use of plasma. In some cases the protective coating is deposited using molecular layer deposition techniques. In certain implementations the protective coating is fluorinated.
