  • Publication number: 20240096012
    Abstract: In an approach to improve the generation of a virtual object in a three-dimensional virtual environment, embodiments of the present invention identify a virtual object to be generated in a three-dimensional virtual environment based on a natural language utterance. Additionally, embodiments generate the virtual object based on a CLIP-guided Generative Latent Space (CLIP-GLS) analysis, and monitor usage of the generated virtual object in the three-dimensional virtual space. Moreover, embodiments infer human perception data from the monitoring, and generate a utility score for the virtual object based on the human perception data.

  • Publication number: 20240078809
    Abstract: Determining contextual relevance of images to automatically generate notifications is provided. An analysis of an image is performed using a set of machine learning models. A context of a current environment of a user captured in the image is determined based on the analysis of the image. A comparison of the context of the current environment of the user is performed against the known information stored in the knowledge corpus. An insight corresponding to the user activity is generated based on the comparison of the context of the current environment of the user against the known information stored in the knowledge corpus. The insight identifies a set of interested parties corresponding to the user who are to be notified and provides proactive assistance to the user to automatically generate a notification in real time. The notification is generated containing the insight corresponding to the user activity.

  • Patent number: 10825679
    Abstract: Methods and apparatuses for selectively depositing silicon oxide on surfaces relative to a metal-containing surface such as copper are provided. Methods involve exposing a substrate having hydroxyl-terminated or dielectric surfaces and copper surfaces to a copper-blocking reagent such as an alkyl thiol to selectively adsorb to the copper surface, exposing the substrate to a silicon-containing precursor for depositing silicon oxide, exposing the substrate to a weak oxidant gas and igniting a plasma, or water vapor without plasma, to convert the adsorb silicon-containing precursor to form silicon oxide. Some methods also involve exposing the substrate to a reducing agent to reduce any oxidized copper from exposure to the weak oxidant gas.

  • Patent number: 10763108
    Abstract: Provided are methods for the selective deposition of material on a sidewall surface of a patterned feature. In some embodiments, the methods involve providing a substrate having a feature recessed from a surface of the substrate. The feature has a bottom and a sidewall which extends from the bottom. A conformal film is deposited on the feature using an atomic layer deposition (ALD) process. The conformal film deposited on the bottom is modified by exposing the substrate to directional plasma such that the conformal film on the bottom is less dense than the conformal film on the sidewall. The modified conformal film deposited on the bottom of the feature is preferentially etched. Also provided are methods for the selective deposition on a horizontal surface of a patterned feature.

  • Patent number: 10662526
    Abstract: A method is provided, including the following operations: simultaneously applying an organosilyl chloride inhibitor and a Lewis base to a surface of a substrate, the organosilyl chloride inhibitor being configured to adsorb onto dielectric regions of the surface of the substrate; performing a plurality of cycles of an ALD process to deposit a metal oxide onto the surface of the substrate; wherein the applying of the organosilyl chloride inhibitor and the Lewis base prevents the ALD process from depositing the metal oxide onto the dielectric regions of the surface of the substrate.

  • Patent number: 10643889
    Abstract: A method of improving selectivity of a metal in a selective deposition process. A pre-treatment process for the metal modifies the metal surface, and includes first reducing the metal to remove organic contamination from the metal followed by oxidation of the metal to allow a monolayer of a metal oxide to grow on the surface. This modification of the metal allows inhibitor molecules to adsorb on the metal oxide monolayer to improve selectivity.

  • Publication number: 20200040454
    Abstract: A method of increasing the deposition rate of an atomic layer deposition (ALD) process by co-flowing a volatile base with metal organic, a metal halide, or metal hybride precursor. The base does not react with the precursor with which it is flowed such that the base generates no measurable film on the substrate or particles in the processing chamber during the flow time. The addition of the base catalyst increases the rate of adsorption of the precursor with which it is flowed.

  • Patent number: 10240236
    Abstract: Apparatuses and methods for cleaning a semiconductor processing chamber is provided. The semiconductor processing chamber may include a UV radiation source, a substrate holder, and a UV transmissive window. The UV transmissive window may include one or multiple panes. One or more panes of the UV transmissive window may be non-reactive with fluorine containing chemistries. In multi-pane windows a purge gas flow path may be formed in the gap between windows. A purge gas may be flowed through the purge gas flow path to prevent process gases used in the chamber interior from reaching one or more panes of the UV transmissive window.
