However , to modify reactivity of the silane , transesterification may be employed
to replace some of the alkoxy groups with a more or less labile group . The extent
of this replacement depends upon the relative concentrations of the two groups ...

Based on our results and previously published work , the minimum relative
dielectric constant for stable FSG films appears to be 3 . 5 . PECVD SiO2 has a
relative dielectric constant of 4 . 1 - 4 . 2 and , if the line pitch and width is kept
constant ...
