Abstract: A semiconductor wafer examination system can accurately and reliably detects defects of semiconductor wafers. The semiconductor wafer examination system 1 comprises a defect classification device for automatically classifying defects of semiconductor wafers on the basis of defect detection parameters and a knowledge base and a classification support device for supporting the operation of the defect classification device. The defect detection parameters define the permissible deviation of the surface image of a defective semiconductor wafer from that of a normal semiconductor wafer. The knowledge base contains data for the types of defects that can occur in semiconductor wafers and data for showing the characteristics of each type. The classification support device prepares data on isolated defective areas that are used for selecting and/or altering the defect detection parameters and preparing the knowledge base.

Abstract: In an exemplary embodiment of the present invention, a high speed optical receiver interface includes a housing adapted to receive a distal end of a fiber having a slanted end face. The slanted end face reflects the received signal along a received optical path. The fiber cladding material along the reflected optical path may be polished or etched to reduce the thickness of the cladding to reduce the separation distance between a photodetector and the slanted end face of the fiber. The reduced separation distance also reduces the beamwidth of the reflected signal that is incident upon the photodetector. An exemplary optical receiver may therefore efficiently couple the incident optical signal onto a photodetector with a reduced active area diameter that is capable of operating at increased data rates.

Abstract: A hydraulic actuator is disclosed having a cylinder with a piston that is moved by hydraulic fluid. A laser diode emits a pulse or pulses of light that form laser light beam. These pulses are provided to two or more optical fibers that extend into two or more corresponding cylinders. For each of these cylinders, the optical fiber enters the cylinder at one end of the cylinder and directs a laser beam into the cylinder, and off the piston where the beam is reflected. The reflected beam then exits the cylinder through at least two corresponding optical fibers disposed on either side of the fiber that conducted the light into the cylinder. Each of the optical fibers that receives reflected light is joined together with the others of the optical fibers into one fiber that carries the reflected beam of light to a photo-diode located remote from the cylinder. Each of the photo diodes for each of the two or more cylinders has a corresponding photo diode amplifier. The output of these amplifiers are coupled together and provided to a pulse expansion circuit. The timing circuit that generates the pulse that triggers the laser diode also generates gate pulses for each of the photo diode amplifiers. These gate signals suppress the output of all but one of the photo diode amplifiers. In this manner, the pulse expansion circuit and phase comparator circuits that receive the photo diode amplifier signals will generate an output signal indicative of the time-of-flight of the laser light pulse in only one cylinder at a time. This permits the system to select a specific cylinder and generate a signal indicative of the position of the piston within the cylinder: the time-of-flight of the laser light pulse.

Abstract: An apparatus for varying the gain of a fiber optic sensor that non-intrusively senses the strain response of a pipe is provided. The apparatus includes a circumferential strain attenuator that has a annular land portion that mechanically couples the attenuator to the pipe. An annular web extends coaxially from the land portion and has a reduced cross sectional area relative to the land and an annular mandrel portion extends coaxially from the web portion and forms a gap between the pipe and the mandrel. The fiber optic sensor is wound on the circumferential strain attenuator. The web and mandrel cooperate to reduce the strain response of the fiber optic sensor relative to the strain response of the pipe.
