  • Patent number: 11396701
    Abstract: Passivation layers to inhibit vapor deposition can be used on reactor surfaces to minimize deposits while depositing on a substrate housed therein, or on particular substrate surfaces, such as metallic surfaces on semiconductor substrates to facilitate selective deposition on adjacent dielectric surfaces. Passivation agents that are smaller than typical self-assembled monolayer precursors can have hydrophobic or non-reactive ends and facilitate more dense passivation layers more quickly than self-assembled monolayers, particularly over complex three-dimensional structures.

  • Patent number: 11387107
    Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity.

  • Patent number: 11381560
    Abstract: A technique for embedding and utilizing credentials in a network address may include requesting a network address for a client device by providing an account identifier to a server computer associated with a service provider. A network address that is mapped to the account identifier can be assigned to the client device. The network address may include a routing prefix field and a network interface identifier field. The routing prefix field may include an issuer identifier of an issuer of the account, and the network interface identifier field may include an interface identifier that maps to the account identifier. By embedding credentials such as an account identifier in the network address, the actual account identifier need not be transmitted to perform actions on the account.

  • Patent number: 11372529
    Abstract: Digital image object anchor point techniques are described that increase user efficiency in interacting with a user interface to create digital images. This is achieved through use of anchor points by the digital image editing system that are defined with respect to an actual geometry of the object. Further, filtering and prioritization techniques are also leveraged to promote real world utility and efficiency of these techniques as a balance between having too many and two few anchor points.

  • Patent number: 11283809
    Abstract: A least-privilege role is automatically assigned to a service principal in order to ensure that a service principal is able to perform actions on a resource of a subscription in a multi-tenant environment as intended without additional access and usage rights. The assignment of the least-privilege role is based on actions previously performed on the resources of a subscription by the service principal that match those actions within a role having the bare minimum permissions needed to perform those actions.

  • Patent number: 11281763
    Abstract: Resource access credential security is improved by providing authentication tools and techniques which do not rely on embedment of credentials in the source code or configuration files of programs that use the credentials to access secured resources. A program under development in a development tool determines through the operation of authentication code that it is under development and that a developer identity is to be used to obtain access credentials, instead of using an identity of the program itself as occurs when the program is not under development. The development tool may be stand-alone, or may be in an integrated development environment, and may be extensible or not. The program may be an application, a web service, or other software, and may be deployed to a cloud or other networked environment. Authentication may be based on a selected developer identity or selected account or other subscriber data.
