1. A method for forming a porous organosilicate film comprising:

  • providing a composite organosilicate film wherein the composite organosilicate film is deposited from a composition comprising at least one silicon-containing precursor and at least one porogen-containing precursor and wherein the composite organosilicate film comprises carbon-containing species;

    exposing the composite organosilicate film to an energy source comprising ultraviolet light; and

    treating the composite organosilicate film to a chemical comprising at least one selected from an oxidizer, a fluorinating agent, a methylating agent, a reducing agent, and combinations thereof to remove at least a portion of the carbon-containing species contained therein and provide a porous organosilicate film.
