  • Publication number: 20210379722
    Abstract: During polishing of a stack of adjacent layers, a plurality of instances of a profile control algorithm are executed on a controller with different instances having different values for a control parameter. A first instance receives a sequence of characterizing values from an in-situ monitoring system during an initial time period to control a polishing parameter, and a second instance receives the sequence of characterizing values during the initial time period and a subsequent time period to control the polishing parameter. Exposure of the underlying layer is detected based on the sequence of characterizing values from the in-situ monitoring system.

  • Patent number: 10951819
    Abstract: One or more techniques and/or systems are provided for ordering images for panorama stitching and/or for providing a focal point indicator for image capture. For example, one or more images, which may be stitched together to create a panorama of a scene, may be stored within an image stack according to one or more ordering preferences, such as where manually captured images are stored within a first/higher priority region of the image stack as compared to automatically captured images. One or more images within the image stack may be stitched according to a stitching order to create the panorama, such as using images in the first region for a foreground of the panorama. Also, a current position of a camera may be tracked and compared with a focal point of a scene to generate a focal point indicator to assist with capturing a new/current image of the scene.

  • Publication number: 20190389028
    Abstract: A method of chemical mechanical polishing includes bringing a substrate having a conductive layer disposed over a semiconductor wafer into contact with a polishing pad, generating relative motion between the substrate and the polishing pad, monitoring the substrate with an in-situ electromagnetic induction monitoring system as the conductive layer is polished to generate a sequence of signal values that depend on a thickness of the conductive layer, determining a sequence of thickness values for the conductive layer based on the sequence of signal values, and at least partially compensating for a contribution of conductivity of the semiconductor wafer to the signal values.

  • Patent number: 10464108
    Abstract: Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which autonomously decontaminate parts. Parts to be cleaned are identified, and based on the identification of the part, a part specific cleaning program is initiated. During the cleaning, the part is manipulated about a gas supply in such a way that the drag force on the contamination particles attached to the part exceeds the contamination particles' surface adhesion force and accordingly is removed from the surface of the part. The removed contamination is then evacuated from the atmospheric environment near the part by a low pressure zone of a second gaseous material near the part.

  • Patent number: 10350723
    Abstract: During polishing of a substrate a first signal is received from a first in-situ monitoring system and a second signal is received from a second in-situ monitoring system. A clearance time at which a conductive layer is cleared and a top surface of an underlying dielectric layer of the substrate exposed and determine based on the first signal. An initial value of the second signal at the determined clearance time is determined. An offset is added to the initial value to generate a threshold value, and a polishing endpoint is triggered when the second signal crosses the threshold value.
