Abstract:
A process for forming a cured, globally planarized, polymeric dielectric thin film on a semiconductor substrate comprising the steps of:(a) depositing a polymeric, dielectric film composition onto a surface of a semiconductor substrate, wherein the polymeric, dielectric film composition comprises a material selected from the group consisting of silicates, phosphosilicates, siloxanes, silsesquioxane, polyarylene ethers, crosslinked polyarylene ethers, fluorinated polyarylene ethers, benzocyclobutene, polyarylene ethers and mixtures thereof;(b) partially curing the deposited film;(c) performing a chemical mechanical polishing step to said partially cured dielectric film, until said dielectric film is substantially planarized; and(d) subjecting the polished film to an additional curing step.
