  • Patent number: 11150140
    Abstract: An apparatus includes a substrate, a nested enclosure assembly including an outer enclosure and an inner enclosure, wherein the outer enclosure encloses the inner enclosure and the inner enclosure encloses at least the electronic assembly. An insulating medium is disposed within a cavity between the outer surface of the inner enclosure and the inner surface of the outer enclosure and the system includes a sensor assembly communicatively coupled to the electronic assembly. The sensor assembly includes one or more sensors that are configured to acquire one or more measurement parameters at one or more locations of the substrate. The electronic assembly is configured to receive the one or more measurement parameters from the one or more sensors.

  • Patent number: 10083852
    Abstract: Edge grippers are disposed around an outer edge of a chuck. Each of the edge grippers includes a finger configured to pivot around a point; a contact pad configured to contact the wafer; and a flexure disposed between the contact pad and the finger. The flexure is configured to flex toward and away from the chuck. The chuck can use a matrix of vacuum and pressure nozzles designed to keep a wafer floating above the chuck. The edge grippers can hold the wafer at the edge while minimizing deformation of the wafer or without affecting z-jitter of the wafer.

  • Patent number: 9514970
    Abstract: Aspects of the present disclosure describe an attachment device for mounting a module to a substrate comprises a module leg with two ends and a module foot. One end of the module leg is configured to be attached to a bottom surface of the module and the other end of the module leg is configured to be attached to the module foot. At least a portion of the module foot is configured to be attached to the substrate. Also a portion of a surface area of the module foot is configured to be exposed outside of an area covered by the module. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 9134186
    Abstract: A process condition measuring device (PCMD) may include first and second substrate components. One or more temperature sensors are embedded within each substrate component. The first and second substrate components are sandwiched together such that each temperature sensor in the second substrate component is aligned in tandem with a corresponding temperature sensor located in the first substrate component. Alternatively first and second temperature sensors may be positioned in parallel in the same substrate. Temperature differences may be measured between pairs of corresponding temperature sensors when the PCMD is subjected to process conditions in a workpiece processing tool. Process conditions in the tool may be calculated from the temperature differences.

  • Patent number: 8681493
    Abstract: A heat shield module includes top and bottom portions made of a high heat material. The top and bottom portions attached to each other and form an enclosure with an opening sized to receive an electronic component package with no intervening insulating material between a component and the top and bottom portions. One or more legs are mounted to either the top portion or the bottom portion. The legs are configured to attach the enclosure to a substrate and to form a gap between the bottom surface of the bottom portion and a top surface of the substrate.
