NOVOLAC POLYMER PLANARIZATION FILMS WITH HIGH TEMPERATURE STABILITY |
摘要 |
A process for forming a planarization film on a substrate that does not smoke or fume on heating includes applying a polymeric solution including a novolac resin having a weight average molecular weight between about 1000 and 3000 amu, which has been fractionated to remove molecules with molecular weight below about 350 amu, a surfactant selected from a group consisting of a non-fluorinated hydrocarbon, a fluorinated hydrocarbon and combinations thereof, and an optional organic solvent to a substrate, followed by heating the substrate.
