A detector set includes a pair of detector units or one detector unit, and a detector row includes a plurality of detector sets in one line. The phase detector includes a plurality of detector rows and each row has a detector set in one period, wherein all detector units are interleaved to have the same interval between any two adjacent detector units, which is defined as a pitch and the pitch is equal to one period dividing the detector pair number, which is the half sum of the number of one detector set for all rows.

    摘要: The present invention relates to a charged particle system for reticle or semiconductor wafer defects inspection and review, and more particularly, relates to an E-beam inspection tool for reticle or semiconductor wafer defects inspection and review without gravitational AMC settling. The charged particle system is an upside down electron beam inspection system with an electron beam aimed upward. The face down design may prevent AMC from gravitational settling on the inspected face of the specimen during inspection, thereafter having a cleaner result compared with conventional face-up inspection system.

    摘要: The present invention relates to a defect review system, and/or particularly, to an apparatus and method of defect review sampling, review method and classification on a semiconductor wafer or a pattern lithography reticle during integrated circuit fabrication. These objects are achieved in comparing a reviewed image with a reference image pick-up through a smart sampling filter. A clustering computer system base on high speed network will provide data cache and save operation time and memory. A smart review sampling filter automatically relocate abnormal pattern or defects and classify the device location extracted from design database and/or from golden die image on the same substrate. The column of the present defect review system is comprised of the modified SORIL type objective lens. This column provides solution of improving throughput during sample review, material identification better image quality, and topography image of defect.

    摘要: A method and system for inspecting a semiconductor wafer. The method includes providing an illumination flux through a pattern plate and a lens to a surface of a specimen to project a pattern onto the surface of the specimen. The pattern is associated with the pattern plate. Additionally, the method includes detecting the illumination flux reflected from the surface of the specimen with a detector, processing information associated with the detected illumination flux, and generating a first image based on at least information associated with the detected illumination flux. The first image includes a first image part for the pattern and a second image part for the specimen. Moreover, the method includes adjusting the lens to a state in order to achieve a first predetermined quality for the first image part, and moving the specimen to a first position.
