Patent number: 4902131Abstract: A novel technique suitable for inspection or examination of the surface condition of a substrate such as a semiconductor wafer. First is one irradiates a light e.g. a laser beam on a substrate surface to focus a scattered light therefrom. Next detects the scattered light focused e.g. with a photomultiplier tube, thus to inspect the substrate surface. When the detection of the scattered light is thus carried out, correction means e.g. a circuit for controlling a voltage applied to the photomultiplier tube, a filter having a variable light-screening factor, a movable iris or an amplification factor adjustment circuit etc. is used to correct the detection sensitivity in accordance with the reflectivity of the substrate surface. Practically, such a corrective operation is carried out on the basis of the intensity of a scattered light or a regularly reflected light from the substrate surface.Type: GrantFiled: March 27, 1986Date of Patent: February 20, 1990Assignee: Kabushiki Kaisha ToshibaInventors: Yuichiro Yamazaki, Motosuke Miyoshi, Shigeru Ogawa, Katsuya Okumura

Patent number: 4626101Abstract: The holding mechanism holds an object under inspection in a manner that the substantially entire surface of the object may relatively be scanned by a laser beam. A spherical integrating light collector has an opening disposed close to the inspected surface of the object held by the holding mechanism. A laser beam illuminating mechanism is coupled with the other end of the spherical integrating light collector, and illuminates the inspected surface of the object with the laser beam through the opening. A photo-electric converter receives the scattered light as is reflected by the inspected surface and collected by the spherical integrating light collector, and converts the scattered light into an electrical signal representing an amount of light. An analog to digital converter converts the electrical signal derived from the photo-electric converter into a digital signal. A peak detector receives the digital signal derived from the analog to digital converter to detect peak values at predetermined periods.Type: GrantFiled: November 26, 1984Date of Patent: December 2, 1986Assignee: Kabushiki Kaisha ToshibaInventors: Shigeru Ogawa, Hiroshi Yamaji, Masaaki Kano
