  • Patent number: 12392427
    Abstract: A polishing assembly includes a chemical mechanical polishing system, a fluid source, and a fluid delivery conduit to carry a fluid from the fluid source into the chemical mechanical polishing system. The chemical mechanical polishing system including a platen to support a polishing pad, a carrier head to support a substrate and bring the substrate into contact with the polishing pad, and a motor to cause relative motion between platen and the carrier head. The fluid delivery conduit includes electrically insulative tubing, a conductive wrapper wrapped around an outer diameter of the tubing from a first end of the tubing to a second end of the tubing, and a conductive wire attached to the conductive wrapper first end. The conductive wrapper is configured to conduct an electrostatic discharge, and the conductive wire is configured to conduct the electrostatic discharge from the conductive wrapper to a grounding source.

  • Publication number: 20230415297
    Abstract: A chemical mechanical polishing system includes a steam generator with a heating element to apply heat to a vessel to generate steam, an opening to deliver steam onto a polishing pad, a first valve in a fluid line between the opening and the vessel, a sensor to monitor a steam parameter, and a control system. The control system causes the valve to open and close in accordance with a steam delivery schedule in a recipe, receive a measured value for the steam parameter from the sensor, receive a target value for the steam parameter, and perform a proportional integral derivative control algorithm with the target value and measured value as inputs so as to control the first valve and/or a second pressure release valve and/or the heating element such that the measured value reaches the target value substantially just before the valve is opened according to the steam delivery schedule.

  • Publication number: 20220337915
    Abstract: Methods, systems, and media for presenting suggestions of media content are provided. In some implementations, the method comprises: determining an item of media content; determining a probability of the item of media content being watched at one or more times based on at least one of: a characteristic of a person; a characteristic of a group; and a characteristic of the item of media content; creating a user interface which suggests that the item of media content be watched at one or more times based on the determined probability; and presenting the user interface.

  • Patent number: 11157579
    Abstract: A delivery coordination system selects restaurant listings for presentation to a user by filtering out restaurants that are unlikely to be of interest to the user, while ensuring that restaurant listings are selected to encourage the success of all restaurants using the delivery coordination system. In response to receiving the listings request from a client device, the delivery coordination system selects a filtered set of restaurant listings from the plurality of restaurant listings stored by the delivery coordination system by applying filtering criteria to the plurality of stored restaurant listings. The delivery coordination system generates conversion scores for the restaurant in the filtered set of restaurant listings and selects restaurant listings to present to the user from the filtered set of restaurant listings based on selection factors, which can include the generated conversion scores. The delivery coordination system transmits the selected restaurant listings to the client device.

  • Patent number: 11100405
    Abstract: Systems and methods for defining a custom segment in a set of behavioral data are provided. A described method includes receiving a set of behavioral data associated with a plurality of user devices and identifying multiple cohort groups, each of the cohort groups including one or more of the user devices. The behavioral data includes a behavior metric for each of the user devices and the cohort groups are identified based on the behavior metric for each of the user devices. The method further comprises generating a segmentation interface including a graphical visualization of the multiple cohort groups and causing the segmentation interface to be presented via a user interface device. The method further comprises defining a custom segment of the behavioral data based on a user selection of one or more of the multiple cohort groups via the segmentation interface.
