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.

Provided are novel methods of filling gaps with a flowable dielectric material. According to various embodiments, the methods involve performing a surface treatment on the gap to enhance subsequent bottom up fill of the gap. In certain embodiments, the treatment involves exposing the surface to activated species, such as activated species of one or more of nitrogen, oxygen, and hydrogen. In certain embodiments, the treatment involves exposing the surface to a plasma generated from a mixture of nitrogen and oxygen. The treatment may enable uniform nucleation of the flowable dielectric film, reduce nucleation delay, increase deposition rate and enhance feature-to-feature fill height uniformity.

Etch profile control with pulsed gas flow and its applications to etching such as anisotropic etching of high aspect ratio features and etching of self-aligned contact structures in various processes. Pulsing can be applied according to this invention to the flow rate of a gas such as an etchant gas, a gas that leads to the deposition of a protective layer, a gas that modifies the deposition of a protective layer, and a gas that modifies etching.

Methods for forming thin dielectric films by selectively depositing a conformal film of dielectric material on a high aspect ratio structure have uses in semiconductor processing and other applications. A method for forming a dielectric film involves providing in a deposition reaction chamber a substrate having a gap on the surface. The gap has a top opening and a surface area comprising a bottom and sidewalls running from the top to the bottom. A conformal silicon oxide-based dielectric film is selectively deposited in the gap by first preferentially applying a film formation catalyst or a catalyst precursor on a portion representing less than all of the gap surface area. The substrate surface is then exposed to a silicon-containing precursor gas such that a silicon oxide-based dielectric film layer is preferentially formed on the portion of the gap surface area. The preferential application of the catalyst or catalyst precursor may occur either at the top of the gap, for example to form a sacrificial mask, or at the bottom of the gap to create a seamless and void-free gap fill.

This invention relates to materials and processes for thin film deposition on solid substrates. Silica/alumina nanolaminates were deposited on heated substrates by the reaction of an aluminum-containing compound with a silanol. The nanolaminates have very uniform thickness and excellent step coverage in holes with aspect ratios over 40:1. The films are transparent and good electrical insulators. This invention also relates to materials and processes for producing improved porous dielectric materials used in the insulation of electrical conductors in microelectronic devices, particularly through materials and processes for producing semi-porous dielectric materials wherein surface porosity is significantly reduced or removed while internal porosity is preserved to maintain a desired low-k value for the overall dielectric material. The invention can also be used to selectively fill narrow trenches with low-k dielectric material while at the same time avoiding deposition of any dielectric on the surface area outside of the trenches.

The present invention comprises a method and computer implemented system for presenting multiple virtual desktops on a display of a computer system. A “pager” window is displayed on a desktop (either real or virtual) which comprises multiple subpanes, each of which contains a scaled virtual desktop having dimensions that are proportional to, but less than the dimensions of a corresponding virtual desktop. Each scaled virtual desktop provides a representation of the corresponding full-size virtual desktop that would display one or more application windows whose content may optionally be replaced by the icon designating the application program or data file displayed therein, for sake of visual clarity. The present invention also provides a mechanism for varying the background image of virtual desktop, and thus, of each scaled virtual desktop pane, in addition to a number of enhancements to the user interface for controlling the virtual desktop environment including transparency hiding of the pager window, constant aspect ratio scaling of the pager window, mouse desktop changing with corner exclusion, display and interaction with window lists, individual pop up menus for windows, starting desktop selection, a method for moving windows between virtual desktops, a method to override virtual desktop behaviors, a method for placing child windows on the same desktop as the parent window, notification of desktop changes, tracking topmost application on other desktops, sticky monitors, and API remote control.

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.

A method of depositing a film on a substrate disposed in a substrate processing chamber. The method includes depositing a first portion of the film by forming a high density plasma from a first gaseous mixture flown into the process chamber. The deposition processes is then stopped and part of the deposited first portion of the film is etched by flowing a halogen etchant into the processing chamber. Next, the surface of the etched film is passivated by flowing a passivation gas into the processing chamber, and then a second portion of the film is deposited over the first portion by forming a high density plasma from a second gaseous mixture flown into the process chamber. In one embodiment the passivation gas consists of an oxygen source with our without an inert gas.
