Abstract:
A method of fabricating a semiconductor device having a multilayer interconnection structure including an interlayer insulation film, comprising the steps of:applying a film-forming liquid on an underlying structure, said film-forming liquid including therein SiO.sub.2 particles and a binder; andheating said underlying structure applied with said film-forming liquid to form an insulation film thereon as said interlayer insulation film, such that said insulation film includes said SiO.sub.2 particles and voids formed between said SiO.sub.2 particles,wherein said SiO.sub.2 particles have a diameter in the range between about 5 nm and about 50 nm, andwherein said step of heating is conducted at a temperature in the range between about 350.degree. C. and about 400.degree. C., in an inert gas atmosphere containing oxygen with a concentration of 1% or less.
