  • Patent number: 10801953
    Abstract: Methods and systems for performing semiconductor measurements based on hyperspectral imaging are presented herein. A hyperspectral imaging system images a wafer over a large field of view with high pixel density over a broad range of wavelengths. Image signals collected from a measurement area are detected at a number of pixels. The detected image signals from each pixel are spectrally analyzed separately. In some embodiments, the illumination and collection optics of a hyperspectral imaging system include fiber optical elements to direct illumination light from the illumination source to the measurement area on the surface of the specimen under measurement and fiber optical elements to image the measurement area. In another aspect, a fiber optics collector includes an image pixel mapper that couples a two dimensional array of collection fiber optical elements into a one dimensional array of pixels at the spectrometer and the hyperspectral detector.

  • Patent number: 10804167
    Abstract: Methods and systems for performing co-located measurements of semiconductor structures with two or more measurement subsystems are presented herein. To achieve a sufficiently small measurement box size, the metrology system monitors and corrects the alignment of the measurement spot of each metrology subsystem with a metrology target to achieve maximum co-location of the measurement spots of each metrology subsystem with the metrology target. In another aspect, measurements are performed simultaneously by two or more metrology subsystems at high throughput at the same wafer location. Furthermore, the metrology system effectively decouples simultaneously acquired measurement signals associated with each measurement subsystem. This maximizes signal information associated with simultaneous measurements of the same metrology by two or more metrology subsystems.

  • Patent number: 10803616
    Abstract: A system generates a user hand shape model from a single depth camera. The system includes the single depth camera and a hand tracking unit. The single depth camera generates single depth image data of a user's hand. The hand tracking unit applies the single depth image data to a neural network model to generate heat maps indicating locations of hand features. The locations of hand features are used to generate a user hand shape model customized to the size and shape of the user's hand. The user hand shape model is defined by a set of principle component hand shapes defining a hand shape variation space. The limited number of principle component hand shape models reduces determination of user hand shape to a smaller number of variables, and thus provides for a fast calibration of the user hand shape model.

  • Publication number: 20200302965
    Abstract: A laser beam is directed through a transmissive axicon telescope or a reflective axicon telescope such as in a magneto-optic Kerr effect metrology system. With the transmissive axicon telescope, a Gaussian beam profile is directed through a first axicon lens and a second axicon lens. The first axicon lens and second axicon lens transfer the Gaussian beam profile of the laser beam to a hollowed laser ring. The laser beam with a hollowed laser ring can be directed through a Schwarzschild reflective objective. With the reflective axicon telescope, the laser beam is directed through two conical mirrors that are fully reflective. One of the conical mirrors defines a central hole that the laser beam passes through.

  • Patent number: 10719953
    Abstract: A system tracks poses of a passive object using fiducial markers on fiducial surfaces of a polygonal structure of the object using image data captured by a camera. The system includes an object tracking controller that generates an estimated pose for a frame of the image data using an approximate pose estimation (APE), and then updates the estimated pose using a dense pose refinement (DPR) of pixels. The APE may include minimizing reprojection error between projected image points of the fiducial markers and observed image points of the fiducial markers in the frame. The DPR may include minimizing appearance error between image pixels of the fiducial markers in the frame and projected model pixels of the fiducial markers determined from the estimated pose and the object model. In some embodiments, an inter-frame corner tracking (ICT) of the fiducial markers may be used to facilitate the APE.

  • Patent number: 10719173
    Abstract: A transcription engine transcribes input received from an augmented reality keyboard based on a sequence of hand poses performed by a user when typing. A hand pose generator analyzes video of the user typing to generate the sequence of hand poses. The transcription engine implements a set of transcription models to generate a series of keystrokes based on the sequence of hand poses. Each keystroke in the series may correspond to one or more hand poses in the sequence of hand poses. The transcription engine monitors the behavior of the user and selects between transcription models depending on the attention level of the user. The transcription engine may select a first transcription model when the user types in a focused manner and then select a second transcription model when the user types in a less focused, conversational manner.
