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.

The process gas also includes dielectric forming precursors such as silicon and oxygen-containing molecules.

Methods of filling high aspect ratio, narrow width (e.g., sub-50 nm) gaps on a substrate are provided. The methods provide gap fill with little or no incidence of voids, seams or weak spots. According to various embodiments, the methods depositing dielectric material in the gaps to partially fill the gaps, then performing multi-step atomic layer removal process to selectively etch unwanted material deposited on the sidewalls of the gaps. The multi-step atomic layer removal process involves a performing one or more initial atomic layer removal operations to remove unwanted material deposited at the top of the gap, followed by one or more subsequent atomic layer removal operations to remove unwanted material deposited on the sidewalls of the gap. Each atomic layer removal operation involves selectively chemically reacting a portion of the fill material with one or more reactants to form a solid reaction product, which is then removed.

A resealable container is provided having a container opening and a rim and a multilayer film covering the container opening and the rim.
