  • Patent number: 9316578
    Abstract: An in-line holographic microscope can be used to analyze on a frame-by-frame basis a video stream to track individual colloidal particles' three-dimensional motions. The system and method can provide real time nanometer resolution, and simultaneously measure particle sizes and refractive indexes. Through a combination of applying a combination of Lorenz-Mie analysis with selected hardware and software methods, this analysis can be carried out in near real time. An efficient particle identification methodology automates initial position estimation with sufficient accuracy to enable unattended holographic tracking and characterization.

  • Publication number: 20150168128
    Abstract: An optical metrology device determines physical characteristics of at least one via in a sample, such as a through-silicon vias (TSV), using signal strength data for modeling of the bottom critical dimension (BCD) and/or for refinement of the data used to determine a physical characteristic of the via, such as BCD and/or depth. The metrology device obtains interferometric data and generates height and signal strength data, from which statistical properties may be obtained. The height and signal strength data for the via is refined by removing noise using the statistical property, and the BCD for the via may be determined using the refined height and signal strength data. In one implementation, a signal strength via map for a via is generated using signal strength data and is fit to a model to determine the BCD for the via.

  • Patent number: 8857951
    Abstract: A large-format printing apparatus includes multiple printing head units. Each of the printing head units can intermittently and steppingly move in a first direction and has a printing nozzle which can move reciprocatingly in a second direction which is perpendicular to the first direction for printing sub-images. Before printing starts, the printing head units are disposed at one end of a printing medium, and arranged to seamlessly splice the sub-images printed by the printing head units into a complete large-format printing image.
