Abstract
Chemical vapor deposition processes are employed to fill high aspect ratio (typically at least 3:1), narrow width (typically 1.5 microns or less and even sub 0.15 micron) gaps with significantly reduced incidence of voids or weak spots. This deposition process involves the use of both hydrogen and fluorine as process gases in the reactive mixture of a plasma-containing CVD reactor. The process gas also includes dielectric forming precursors such as silicon and oxygen-containing molecules.
