摘要： The present invention relates to novel low dielectric constant nanoporous dielectric films having improved mechanical strength, and to improved processes for producing the same on substrates suitable for use in the production of integrated circuits. The nanoporous dielectric films are prepared by a process of preparing a mixture of a spin-on-glass material with a suitable thermally degradable polymer that is soluble in nonpolar solvents. Applying the resulting mixture onto a substrate suitable for use in the production of an integrated circuit, to produce a coated substrate. The coated substrate is then heated for a time and at one or more temperatures effective to remove the thermally degradable polymer, so as to produce the desired low dielectric nanoporous dielectric film.
