Abstract:
A method of fabricating a semiconductor device, comprising the steps of:forming an interlayer insulation film of an organic polymer on a substrate; forming an organic spin-on-glass film on said interlayer insulation film before patterning said interlayer insulation film; patterning said organic spin-on-glass film and said interlayer insulation film to form a depression such that said depression penetrates through said organic spin-on-glass film and reaches said interlayer insulation film; depositing a conductor layer on said organic spin-on-glass film so as to fill said depression; and removing a part of said conductor layer locating above said organic spin-on-glass film by a chemical mechanical polishing process, to form a conductor pattern filling said depression, said chemical mechanical polishing process being conducted while using said organic spin-on-glass film as a polishing stopper.
