Abstract

A method for reforming an insulating film such as a BSG film formed by a CVD technique. The method reduces the parasitic capacitance between conductor layers having an intervening film, especially a BSG film, and includes the steps of depositing a BSG film on a substrate from a gaseous source and exposing the BSG film to a reforming gas plasma.
