  • Inspection apparatus
    Patent number: 9933370
    Abstract: When a size of a block on a wafer is equal to or smaller than an optical resolution of imaging optics, room for improvement in a signal-to-noise ratio has not been sufficiently considered in a conventional technique. One feature of the defect determination of the present invention is to include a filter processing for setting a predetermined partial area serving as a predetermined matrix for a first difference image, scanning the first difference image in the partial area, and outputting a second difference image, and a first threshold processing using a first threshold value for the second difference image. As a result, highly sensitive defect detection can be achieved.

  • Thermal shock resistance testing method and thermal shock resistance testing apparatus
    Patent number: 9885616
    Abstract: A ceramic body is heated to a predetermined temperature by using a furnace, and a cooling gas is ejected toward a first end face of the ceramic body so that the first end face of the ceramic body is cooled. At this time, the temperature of the first end face of the ceramic body is measured by a radiation thermometer provided on the same side from which the cooling gas is ejected, and the internal temperature is measured by a thermocouple provided in the ceramic body. Thereafter, a thermal shock resistance test in which actual use conditions are simulated is performed by obtaining the temperature gradient of the ceramic body from measurement results of the temperature of the first end face of the ceramic body and the internal temperature and checking the absence or presence of cracks that occurs to the ceramic body.

  • Surface measurement apparatus
    Patent number: 9823065
    Abstract: The invention discloses a technique that estimates micro roughness from a total sum of detection signals from plural detection systems and signal ratios, using a light scattering method. The technique rotates and translates a wafer at high speed to measure the entire surface of the wafer with high throughput. The relationship between the micro roughness and the intensity of scattered light varies according to a material of the wafer and a film thickness thereof. Moreover, calibration of an apparatus is also necessary. Thus, for instance, the invention provides a technique that has a function of correcting an optically acquired detection result using a sample which is substantially the same as a measurement target and makes the optically acquired detection result come close to a result measured by an apparatus, such as an AFM, using a different measurement principle.
