  • Publication number: 20240006207
    Abstract: A bonding apparatus includes a first holder; a second holder; a horizontally moving unit; an elevating unit; an inclination measuring unit; and a controller. The first holder is configured to attract and hold a first substrate on a bottom surface thereof. The second holder is disposed under the first holder and configured to attract and hold a second substrate on a top surface thereof. The horizontally moving unit is configured to move the first substrate and the second substrate relative to each other in a horizontal direction. The elevating unit is configured to move the second substrate up and down between a proximate position and a spaced position. The inclination measuring unit is configured to measure an inclination of the second holder. The controller calculates a position of the second substrate in the horizontal direction based on a measurement result of the inclination measuring unit.

  • Publication number: 20230290659
    Abstract: A computer-readable recording medium having stored thereon computer-executable instructions that, in response to execution on a computer, cause a processing to be performed is provided. The processing includes acquiring displacement data of multiple points on a surface of a substrate held by a chuck; specifying a distribution of displacements of the surface based on the acquired displacement data; and determining a type of a foreign matter based on the specified distribution.

  • Patent number: 6597448
    Abstract: A system and method of inspecting a foreign particle or a defect on a sample are provided. Such a method comprises irradiating light to an object to be inspected; detecting reflected light or scattered light from the object to be inspected irradiated with the light; detecting a signal of the foreign particle or the defect from the detected signal; providing information related to a size of the foreign particle or the defect from the signal of the detected foreign particle or the defect; and outputting information on a display screen a distribution of the size of the foreign particle or defect with information indicating a cause of the distribution of the foreign particle or defect.
