  • Patent number: 11137356
    Abstract: A method for exposing a buried defect, the method may include illuminating, by a radiation source, an object that comprises the buried defect, with illuminating radiation that passes through radiation transparent part of a chuck, while the object is supported by the chuck; detecting, by a sensor, a detected radiation that passed through the object, to provide a visual indication about the buried defect, wherein the visual indication is indicative of a location of the buried defect; setting, based on the location of the buried object and a spatial relationship between a cleaving element and the sensor, a cleaving axis of a cleaving element to virtually cross the buried defect; and cleaving, by the cleaving element, the object to expose the buried object.

  • Patent number: 5740953
    Abstract: A method and apparatus are described for cleaving a relatively thin semiconductor wafer for inspecting a target feature on a workface thereof by: producing, on a first lateral face of the semiconductor wafer, laterally of the workface on one side of the target feature, an indentation in alignment with the target feature; and inducing by impact, in a second lateral face of the semiconductor wafer, laterally of the workface on the opposite side of the target feature, a shock wave substantially in alignment with the target feature and the indentation on the first lateral face, to split the semiconductor wafer along a cleavage plane essentially coinciding with the target feature and the indentation.
