Patent number: 5952243Abstract: A method for forming a gap-filled, planarization structure of dielectric materials on a substrate topography useful for forming microelectronic devices. A dielectric material is first deposited as continuous, dry dielectric layer, preferably a SOG layer. Then the dielectric layer is partially removed by chemical-mechanical polishing (CMP). The chemical and mechanical properties of the structure can be chosen by varying the composition of the SOG layer and the subsequent CMP conditions.Type: GrantFiled: June 24, 1996Date of Patent: September 14, 1999Assignee: AlliedSignal Inc.Inventors: Lynn Forester, Dong K.
