  • Patent number: 6329219
    Abstract: A semiconductor device, such as a back side illuminated CCD, is fabricated by forming an insulating layer over the front side of a body of semiconductor material, depositing a layer of high resistivity material over the front side of the insulating layer, patterning a portion of the layer of high resistivity material to form a long and narrow trace, and attaching a support member to the front side of the insulating layer. In the case of a back side illuminated CCD, the patterning of the layer of high resistivity material advantageously forms a long and narrow trace substantially confined to a peripheral area of the front side of the insulating layer and the semiconductor material is removed from the corresponding peripheral area of the back side of the insulating layer, leaving a plateau of semiconductor material that does not extend over the area that contains the long and narrow trace.

  • Patent number: 6313910
    Abstract: Apparatus for real time measurement of optical beam parameters includes an assembly of known dimensions, carrying multiple apertures, occupying parallel planes. The assembly can be moved so that the apertures sequentially intersect an optical beam which is not propagated in the plane of the apertures. At least one pair of the apertures are non-circular and identical with accurately established positions and which are not disposed in the same angular alignment when they intercept the beam but are disposed in the same plane in order to allow determination of the two-dimensional position of the centroid of the beam in that plane.
