Image Number 16 for United States Patent #8017516.
A system and method for forming a planar dielectric layer includes identifying a non-planarity in the dielectric layer, forming one or more additional dielectric layers over the dielectric layer and planarizing at least one of the additional dielectric layers wherein the one or more additional dielectric layers include at least one of a spin-on-glass layer and at least one of a low-k dielectric material layer and wherein each one of the one or more additional dielectric layers having a thickness of less than about 1000 angstroms and wherein the one or more additional dielectric layers has a total thickness of between about 1000 and about 4000 angstroms.
