  • Publication number: 20210270868
    Abstract: A semiconductor tester and a method for calibrating a probe card and a device under testing (DUT) are disclosed. The semiconductor tester includes: a support platform, including a support surface and configured to be able to move along a direction parallel to the support surface and rotate around a rotating shaft perpendicular to the support surface; a probe card including a plurality of probes stretching towards the support platform; and an alignment assembly, including: at least two first laser emitting apparatuses emitting a plurality of first laser beams; and a second laser emitting apparatus emitting a plurality of second laser beams. The first laser beams and the second laser beams are perpendicular to each other and are each arranged sequentially along a direction perpendicular to the support surface. The semiconductor tester aligns a probe card to a DUT with improved accuracy, thereby preventing the damage to the probe card.

  • Patent number: 10803603
    Abstract: Disclosures of the present invention describe a moving object detection system and method, wherein a pre-processer module, a feature extraction module, an image optical flow estimation module, a feature points grouping module, and a moving object determination module are provided in a controlling and processing module of the system by a form of library, variables, or operands. Moreover, a feature difference calculation unit, a matrix establishing unit and a corner feature point acquiring unit are provided in the feature extraction module, and that is helpful for enhancing computing speed of the controlling and processing device in verifying corner feature points from image frames. Therefore, after the corner feature points are applied with a cluster labeling process, the moving object determination module can achieve motion detection of at least one object locating in a monitoring area by determining whether corner feature point groups move or not.
