A method of forming a low-k dielectric layer or film includes forming a porous low-k dielectric layer or film over a wafer or substrate. Active bonding is introduced into the porous low-k dielectric layer or fihm to improve damage resistance and chemical integrity of the layer or film, to retain the low dielectric constant of the layer and film after subsequent processing. Introduction of the active bonding may be accomplished by introducing OH and/or H radicals into pores of the porous low-k dielectric layer or film to generate, in the case of a Si based low-k dielectric layer or film, Si-OH and/or Si-H active bonds. After further processing of the low-k dielectric film, the active bonding is removed from the low-k dielectric layer or film.
