  • Patent number: 6580091
    Abstract: A top surface of a wafer is provided with an n-type source region, an n-type drain region, and an n-type semiconductor region. Dry etching using a plasma is performed with respect to an interlayer insulating film deposited on the wafer to form openings reaching the respective regions, followed by light etching for removing a damaged layer. In this case, exciting light is supplied intermittently to the n-type semiconductor region. The progression of the removal of the damaged layer and the stage of development of a newly damaged layer are sensed by monitoring the change rate of the intensity of reflected probe light in the presence and absence of the exciting light, resulting in the formation of a semiconductor device having low and equal contact resistance. In-line control using optical evaluation enables the implementation of semiconductor devices with excellent and consistent properties.

  • Patent number: 4886347
    Abstract: A range-finding binocular is disclosed which has substantially the external appearance and size of a conventional binocular. In each barrel, a system is provided for obtaining a projected image of a range-mark of circular symmetry which is focused in the focal plane of each eye lens at an accurately placed position near the visual axis of the monocular. The distance between the projected image and the visual axis is carefully controlled in order to provide, in stereovision, a sense of distance to the range-mark image which can be "placed alongside" a target of interest by changing the offset distance in a controlled manner. In one embodiment, the image is obtained by a backlighted reticle whose image passes between a transparent glass range-mark translation plate and a transparent glass adjustment plate, through a lens, and to a gold surfaced mirror for directing the projected image into the conventional path of the field of view.

  • Patent number: 4355904
    Abstract: A scanning laser measurement system for measuring depthwise variations of surfaces relative to a focal plane of an optical system. Laser light is directed to a test surface, generally aligned with the focal plane, through focusing optics having an optical axis. Some of the light from a beam spot is retro scattered from the test surface and reimaged along a path generally parallel to the optical axis. Depthwise variations in the test surface with respect to the focal plane cause spatial displacements in the retrobeam relative to the optical axis. The retrobeam is directed to a filter which is partially reflective and partially transmissive. A pair of photodetectors is used to intercept reflected and transmitted components of the retrobeam and the intensity of these components is measured and used to compute centroid values for the retrobeam on the filter for various beam spots on the test surface. The computed centroid values are directly proportional to depthwise surface deviations from the focal plane.

  • Patent number: 4204772
    Abstract: A non-contacting optical probe incorporates an optical system designed to measure distances between various surfaces which may be internal or external such as exists in molds and the like. A collimated light beam is passed off-center through a first lens and focused to a first point on a first surface coplanar with the focal plane of the lens. When the distance between the first surface and the optical probe carrying the collimated beam changes so that a second surface is presented, this second surface is no longer in the focal plane with the result that a laterally displaced image of the point of interception of the collimated beam with the point of the intersection of the optical axis of the system occurs. This lateral displacement is imaged back through the optical system to a sensing surface.
