  • Patent number: 10831108
    Abstract: Methods are provided for deriving a partially continuous dependency of metrology metric(s) on recipe parameter(s), analyzing the derived dependency, determining a metrology recipe according to the analysis, and conducting metrology measurement(s) according to the determined recipe. The dependency may be analyzed in form of a landscape such as a sensitivity landscape in which regions of low sensitivity and/or points or contours of low or zero inaccuracy are detected, analytically, numerically or experimentally, and used to configure parameters of measurement, hardware and targets to achieve high measurement accuracy. Process variation is analyzed in terms of its effects on the sensitivity landscape, and these effects are used to characterize the process variation further, to optimize the measurements and make the metrology both more robust to inaccuracy sources and more flexible with respect to different targets on the wafer and available measurement conditions.

  • Patent number: 10670383
    Abstract: A measuring arrangement is calibrated for determining rotational positions of a rotary device that has a first part and a second part which can be rotated relative to the first part about a rotational axis. Rotational positions of the first part relative to the second part and/or rotational positions of the second part relative to the first part are detected using a plurality of sensors distributed about the rotational axis. A respective measurement signal corresponding to each detected rotational position is generated such that redundant information on the rotational positions of the first part and the second part relative to each other is provided. The redundant information on the rotational position(s) are analyzed such that effects of a translational movement of the first and the second part relative to each other are corrected, the translational movement running transverse to the extension of the rotational axis.

  • Patent number: 10537997
    Abstract: Embodiments described herein generally relate to an apparatus and method of performing a robot calibration process within a substrate processing system. In one embodiment, a calibration device is used to calibrate a robot having an end effector. The calibration device includes a body, a first side and a second side opposite to the first side. The calibration device further includes a sensor disposed on the second side of the body. In some embodiments, the sensor covers the entire second side of the body. In this configuration, because the sensor covers the entire second side of the body of the calibration device, the calibration device can be utilized to sense the contact between the sensor and various differently configured chamber components found in different types of processing chambers or stations disposed within a processing system during a calibration process performed in each of the different processing chambers or stations.

  • Patent number: 10504269
    Abstract: Inertial damping is used to improve the simulation of deformable bodies for physics-based animation. Using this technique, undesirable dynamics of deformable bodies can be suppressed or completely removed while retaining other, more desirable dynamics. An inertial damping module selectively applies inertial damping to a subset of the dynamic modes of a simulated system (e.g., by using the quasi-static solution for these modes or reducing their magnitude). Thus, when the dynamics are simulated, the interactions between modes can be retained while the undesirable effects of the damped modes are reduced or eliminated. The results of the simulation are used to drive a physics-based animation.

  • Patent number: 10314522
    Abstract: Disclosed are a system, a method, and a program for initializing an attachment location of a measurement sensor. The method of initializing an attachment location of at least one measurement sensor includes requesting selection of the measurement sensor that is attached to a specific body unit (S100); recognizing identification information of the measurement sensor, which agrees with a selection manipulation of the measurement sensor (S200); matching the identification information with the body unit (S300); and determining sensing data received from the measurement sensor, which corresponds to the identification information, as motion data of the body unit. According to the inventive concept, because attachment locations of a plurality of measurement sensors are initialized, a terminal may accurately calculate a posture or motion of the user.

  • Patent number: 10203613
    Abstract: Positional information of a movable body in a Y-axis direction is measured using an interferometer and an encoder whose short-term stability of measurement values excels when compared with the interferometer, and based on the measurement results, a predetermined calibration operation for obtaining correction information for correcting measurement values of the encoder is performed. Accordingly, by using measurement values of the interferometer, correction information for correcting the measurement values of the encoder whose short-term stability of the measurement values excels the interferometer is obtained. Then, based on the measurement values of the encoder and the correction information, the movable body is driven in the Y-axis direction with good precision.
