Abstract: An inspection apparatus projects a laser beam on the surface of a SOI wafer and detects foreign matter on and defects in the surface of the SOI wafer by receiving scattered light reflected from the surface of the SOI wafer. The wavelength of the laser beam used by the inspection apparatus is determined so that a penetration depth of the laser beam in a Si thin film may be 10 nm or below to detect only foreign matter on and defects in the outermost surface and not to detect foreign matter and defects in a BOX layer. Only the foreign matter on and defects in the outermost surface layer can be detected without being influenced by thin-film interference by projecting the laser beam on the surface of the SOI wafer and receiving scattered light rays.

Abstract: A two-dimensional sensor is installed inclining at a predetermined angle to a moving direction of a stage on which an object to be inspected is mounted and, in synchronism with the movement of the stage, a picked up image is rearranged so that there can be obtained an image in high-density sampling with a picture-element size or less of the two-dimensional sensor with respect to a wafer. Thus, interpolation calculation during position alignment becomes unnecessary, and size calculation and classification of a defect can be performed with high accuracy.

Abstract: A method and apparatus for detecting defects are provided for detecting harmful defects or foreign matter with high sensitivity on an object to be inspected with a transparent film, such as an oxide film, by reducing noise due to a circuit pattern. The apparatus for detecting defects includes a stage part on which a substrate specimen is put and which is arbitrarily movable in each of the X-Y-Z-θ directions, an illumination system for irradiating the circuit pattern with light from an inclined direction, and an image-forming optical system for forming an image of an irradiated detection area on a detector from the upward and oblique directions. With this arrangement, diffracted light and scattered light caused on the circuit pattern through the illumination by the illumination system is collected. Furthermore, a spatial filter is provided on a Fourier transform surface for blocking the diffracted light from a linear part of the circuit pattern. The scattered and reflected light received by the detector from the specimen is converted into an electrical signal. The converted electrical signal of one chip is compared with that of the other adjacent chip. If these signals are not identical to each other, the foreign matter is determined to exist on the specimen in detection.

Abstract: An optical transmission system accomplishes optical transmission over a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission over a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-toelectric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, and with no use of any optical booster amplifier and optical preamplifier in multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.
