摘要: A method for repairing and lowering the dielectric constant of low-k dielectric layers used in semiconductor fabrication is provided. In one implementation, a method of repairing a damaged low-k dielectric layer comprising exposing the porous low-k dielectric layer to a vinyl silane containing compound and optionally exposing the porous low-k dielectric layer to an ultraviolet (UV) cure process.
