Abstract

The present invention relates to low dielectric constant nanoporous silica films and to processes for their manufacture. A substrate, e.g., a wafer suitable for the production of an integrated circuit, having a plurality of raised lines and/or electronic elements present on its surface, is provided with a relatively high porosity, low dielectric constant, silicon-containing polymer film composition.
