Abstract: A defect review system includes a stage, a light source, a turning mirror, and a ring of collectors. The stage supports and moves an article for inspection, the article having a surface. The light source provides light. The turning mirror turns the light toward the surface at an oblique incident angle whereby the light illuminates a spot on the surface and the light scatters from the spot. The ring of collectors is adapted to collect scattering light. A method of reviewing surface of a wafer is disclosed. The method provides a dark-field mode of operation adapted to inspect the surface by illuminating a spot on the surface at an oblique angle and collecting scattering light from the surface. Further, the method provides a bright-field mode of operation adapted to inspect the surface by illuminating a spot on the surface at a normal angle to examine the reflecting light.

Abstract: This disclosure relates to a coated wire, an extrusion die, a process of coating a wire and a method of testing wrinkles on covering of a coated wire. A coated wire comprises a wire core; and a covering comprising a thermoplastic composition which comprises by weight of total composition, (i) 10% to 50% of a poly(arylene ether); (ii) 5% to 25% of a polyolefin; and (iii) 15% to 45% of an impact modifier. The wrinkles presented on the covering of a coated wire manufactured by an extrusion die are substantively reduced.

Abstract: An inspection system includes a stage, a light source, and a light collection subsystem is disclosed. The stage supports an article for inspection, the article having a surface. The light source provides light impinging on and scattering from an illumination area of the surface. The light collection system includes a plurality of collectors arranged generally in a semi-spherical layout such that each collector collects at least a portion of the scattering light at a collection polar angle and a collection azimuthal angle that are unique relative to collection polar angle and collection azimuthal angle of other collectors. The collectors are arranged in three rings of collectors. The inspection system includes a plurality of channels where each collector of the light collection subsystem is associated with a channel. The inspection system includes a processor connected to the channels. The processor is adapted to process information from the channels.

Abstract: A system for analyzing an object has two operating modes such as scanned imaging mode and stop scan spectral analysis mode. A beam scanner is optically connected to a laser to receive laser beams from the laser. Beam scanner also scans the beams if the system is in the scanned imaging mode. A lens (e.g., an objective lens) is optically coupled to the beam scanner to focus the beams received from the beam scanner. A sensor is optically coupled to the lens to receive the beams that reflect from the object. The sensor may detect characteristics of the beam such as color and intensity. A spectrometer is optically coupled to the objective lens. During stop scan spectral analysis mode, spectrometer generates wavelength spectrum data.

Abstract: Disclosed is method of adjusting a microscope aperture to obtain the highest possible defect detection rate for a particular type of target. According to the method, an operator obtains an image of a calibration target and visually analyzes the image for defects. The operator then uses a defect detection process to analyze the image to obtain another set of defect information. This second set of defect information is compared with the visually obtained defect information to determine the accuracy of the defect detection performed by the defect detection process: a perfect match indicates 100% accurate defect detection. The operator then changes the aperture diameter and repeats the process to obtain a second set of defect information. This second set of defect information is, like the first set, compared with the visually obtained defect information. This process is repeated as many times as are necessary to determine which aperture diameter results in the highest defect detection rate.
