  • Publication number: 20230314128
    Abstract: A processing system and a charged particle beam apparatus for the purpose of determining the degree of growth or the presence or absence of a defect in an epitaxial layer grown in a groove or a hole such as between inner spacers from an image of the groove or the hole are proposed. In a processing system including a computer system, the computer system calculates a distance and a brightness value related to a layer between a plurality of structures from a signal profile in accordance with one direction on a two-dimensional plane related to the layer, which is obtained by irradiating the layer with an electron beam, and determines or outputs a state of the layer based on the distance and the brightness value.

  • Publication number: 20220230281
    Abstract: Proposed is a technique that can detect a random noise component at high accuracy without measurement pattern limitation and enables edge roughness measurement at higher accuracy. According to this disclosure, pattern matching and edge position correction are performed with respect to each of the left edge and the right edge of a line pattern in an obtained line pattern image, and an image with no roughness is generated. A PSD value is measured from the image, and the average PSD value of all the frequencies is determined as a random noise component, so that the random noise component can be detected at high accuracy. Further, the PSD value (random noise component) is subtracted from the PSD value of an original image, thereby measuring edge roughness at high accuracy.
