Conformal nanolaminate dielectric deposition and etch back processes that can fill high aspect ratio (typically at least 5:1, for example 6:1), narrow width (typically sub 0.13 micron, for example 0.1 micron or less) gaps with significantly reduced incidence of voids or weak spots involve the use of any suitable confirmal dielectric deposition technique and a dry etch back. The etch back part of the process involves a single step or an integrated multi-step (for example, two-step) procedure including an anisotropic dry etch followed by an isotropic dry etch. The all dry deposition and etch back process in a single tool increases throughput and reduces handling of wafers resulting in more efficient and higher quality nanolaminate dielectric gap fill operations.

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.

In-situ semiconductor process that can fill high aspect ratio (typically at least 6:1, for example 7:1 or higher), narrow width (typically sub 0.13 micron, for example 0.1 micron or less) gaps with significantly reduced incidence of voids or weak spots is provided. This deposition part of the process may involve the use of any suitable high density plasma chemical vapor deposition (HDP CVD) chemistry. Prior to etch back, the feature gap is plugged with an etch selectivity layer. The etch back part of the process involves multiple steps including a sputter etch to reduce the top hat formations followed by a reactive plasma etch to open the gap. This method improves gapfill, reduces the use of high cost fluorine-based etching and produces interim gaps with better sidewall profiles and aspect ratios.
