Abstract
Within a method for forming a microelectronic fabrication there is first provided a substrate. There is then formed over the substrate a patterned conductor layer having a topographic variation at a periphery of the patterned conductor layer. There is then formed over the substrate and passivating the topographic variation at the periphery of the patterned conductor layer a planarizing passivation layer formed of a thermally reflowable material. There is then formed upon the planarizing passivation layer a dimensionally stabilizing layer. Finally, there is then thermally annealed the microelectronic fabrication to form from the planarizing passivation layer a thermally annealed planarizing passivation layer. By employing formed upon the planarizing passivation layer the dimensionally stabilizing layer, there is attenuated within the thermally annealed planarizing passivation layer replication of the topographic variation at the periphery of the patterned conductor layer.
