Abstract
A novel multilevel interconnection system for bipolar or BiCMOS LSIs was developed. Bias sputtered quartz (BSQ) and plasma CVD SiO(P-SiO) constituted the stacked interlayer, making it possible to smooth high aspect ratio (0.82) topography. The electrical properties of the films and the manufacturing-process damage were investigated. The results show that the stacked structure offers good electrical stability and reliability. This system was successfully applied to real devices.<>
