Paper Abstract

This paper describes effects of spin-on-glass (SOG) planarization layer etchback process on reliability of submicron vias for multilevel metalization. Resistance values of double-level metal via chains containing 4,000-200,000 vias in the 0.8-2.0 um size range have been measured. Mass spectra for outgas from SOG films have been studied in more detail. The SOG etchback process and the subsequent P-SiO layer deposition process have been executed in a multichamber CVD system. The multichamber processing can reduce the emission of outgas which degrades via yield and reliability.
