  • Publication number: 20180024904
    Abstract: A test support device includes a processor configured to acquire event information on events which occur during an execution of a target program. The processor is configured to classify the events into event groups on basis of similarity of timings at which the respective events occur. The processor is configured to calculate, for each of the event groups, a summed value of evaluation values of the respective events classified into the relevant event group. The processor is configured to determine for each of the event groups, on basis of the summed value, whether a breakpoint of a target process executed by the target program is present at a timing corresponding to the relevant event group. The processor is configured to display timing information indicating a timing at which a breakpoint is determined to be present, in association with elapsed time after a start of executing the target program.

  • Patent number: 9327488
    Abstract: A carrier and a substrate are aligned even if an imager cannot be simultaneously focused on alignment marks formed on both the carrier and the substrate. Center of gravity positions G1m of an alignment pattern element AP1 on a substrate and G2m of an alignment pattern element AP2 on a transparent blanket are calculated by image processing from an image IM imaged via the blanket by a CCD camera. The position of the center of gravity Gm2 is specified by a process associated with edge extraction from the image imaged with the alignment pattern element AP2 on the blanket being in focus. High spatial frequency components are removed and low frequency components are extracted for the alignment pattern element AP1 on the substrate imaged out of focus to have a blurred outline, and the position of the center of gravity G1m is specified from an extraction result.

  • Patent number: 9064922
    Abstract: A substrate inspection apparatus for detecting a condition of an EBR line at a substrate edge, comprising a turntable for rotating a substrate having a film coated thereon, a light irradiator and a photoelectric converter that receives specularly reflected light from the substrate and outputs a captured image signal.

  • Publication number: 20140209250
    Abstract: In a detaching apparatus, a detachment starter bends one end part of a first plate-like body into a cylindrical or prismatic surface in a direction opposite to a second plate-like body, thereby forming a single and straight boundary line between an adhering region and a detached region. A separator increases a distance between a first holder holding the first plate-like body and a second holder holding the second plate-like body to separate the first and second plate-like bodies.
