  • Patent number: 9105444
    Abstract: An electro-optical inspection apparatus is provided that is capable of preventing adhesion of dust or particles to the sample surface as much as possible. A stage (100) on which a sample (200) is placed is disposed inside a vacuum chamber (112) that can be evacuated to vacuum, and a dust collecting electrode (122) is disposed to surround a periphery of the sample (200). The dust collecting electrode (122) is applied with a voltage having the same polarity as a voltage applied to the sample (200) and an absolute value that is the same or larger than an absolute value of the voltage. Thus, because dust or particles such as particles adhere to the dust collecting electrode (122), adhesion of the dust or particles to the sample surface can be reduced. Instead of using the dust collecting electrode, it is possible to form a recess on a wall of the vacuum chamber containing the stage, or to dispose on the wall a metal plate having a mesh structure to which a predetermined voltage is applied.

  • Publication number: 20150122993
    Abstract: A substrate is irradiated by primary electrons and secondary electrons generated from the substrate are detected by a detector. A reference die is placed on the stage to obtain a pattern matching template image including feature coordinates of the reference die. A pattern matching is performed with an arbitrary die in a row or column including the reference die using the template image to obtain feature coordinates of the arbitrary die. An angle of misalignment is calculated between the direction of the row or column including the reference die and one of the directions of movement of the substrate on the basis of the feature coordinates of the arbitrary die and those of the reference die. The stage is rotated to correct the angle of misalignment to conform the direction of the row or column including the reference die with the one of the directions of movement of the substrate.
