    摘要: The present invention relates to a high-sensitivity inspection method and apparatus adapted for the fine-structuring of patterns, wherein defect inspection sensitivity is improved using the following technologies: detection optical system is improved in resolution by filling the clearance between an objective lens 30 and a sample 1, with a liquid, and increasing effective NA (Numerical Aperture); and when a transparent interlayer-insulating film is formed on the surface of the sample, amplitude splitting at the interface between the liquid and the insulating film is suppressed for reduction in the unevenness of optical images in brightness due to interference of thin-film, by immersing the clearance between the objective lens and the sample, with a liquid of a refractive index close to that of the transparent film.

    摘要: A pattern detection method and apparatus for inspecting, with high resolution, a micro fine defect of a pattern on an inspected object, and a semiconductor substrate manufacturing method and system with a high yield. A micro fine pattern on the inspected object is inspected by annular-looped illumination through an objective lens onto a wafer, the wafer having micro fine patterns thereon. The illumination may be polarized and controlled according to an image detected on the pupil of the objective lens, and image signals are obtained by detecting a reflected light from the wafer. The image signals are compared with reference image signals and a part of the pattern showing inconsistency is detected as a defect. Simultaneously, micro fine defects on the micro-fine pattern are detected with high resolution. Further, process conditions of a manufacturing line are controlled by analyzing a cause of defect and a factor of defect.

    摘要: A pattern checking method wherein an image of a certain position of one pattern is detected; the detected image is positioned with respect to an image of a position corresponding to the certain position, in a reference pattern image; and the positioned images are compared with each other, whereby a discrepant place among these positioned images is judged as a defect the positioning operations of the images of the detected patterns are controlled based upon either pattern information such as density of the images of the detected patterns, or information obtained from the positioning operations for images of other positions in the patterns. An image sensor unit for detecting images of patterns is constructed which has such a structure that a plurality of one-dimensional image sensors functioning as a pattern detector are arranged in a two-dimensional form, and an output of a certain one-dimensional image sensor for imaging a certain position of one pattern is delayed for a predetermined time period, and also both of an output of an one-dimensional image sensor adjoining the first-mentioned one-dimensional image sensor, which images the same position of the same pattern, and the delayed output of the certain one-dimensional image sensor are sequentially added to derive a summation output. The image sensor unit is inclined at a predetermined angle with respect to a plane perpendicular to the reflection light from the patterns, and the reflection light from the patterns is focused via a confocal focusing optical system onto this image sensor unit.
