Patent number: 6909772Abstract: An apparatus and method for mapping film thickness of textured polycrystalline thin films. Multiple sample films of known thicknesses are provided, and each is irradiated by x-ray at a measurement point to generate a diffraction image that captures a plurality of diffraction arcs. Texture information (i.e., pole densities) of each sample film is calculated based on multiple incomplete pole figures collected from the diffraction image and used to correct the x-ray diffraction intensities obtained from such sample film. Corrected and integrated diffraction intensities of the sample films are then correlated to respective known film thicknesses of such films, and the correlation so determined can be used to map the film thickness of a textured polycrystalline thin film of unknown thickness, based on the corrected and integrated diffraction intensity calculated for such thin film.Type: GrantFiled: December 23, 2003Date of Patent: June 21, 2005Assignees: HyperNex, Inc., International Business Machines Corp.Inventors: Krzysztof J. Kozaczek, David S. Kurtz, Paul R. Moran, Roger I. Martin, Patrick W. Dehaven, Kenneth P. Rodbell, Sandra G. Malhotra

Patent number: 6882739Abstract: An apparatus and method for performing rapid grain size analysis on a textured polycrystalline material, by generating average grain size and grain size distribution data from x-ray diffraction data of such material. Raw diffraction data is obtained by capturing a plurality of diffraction arcs within a single data capture frame. The raw diffraction data is digitally registered; (3) and the registered diffraction data is filtered to remove background noise, exclude diffraction overlaps or truncations, and compensate for biased data obtained from regions of highly preferred orientations. Average grain size and grain size distribution data are then correlated with the filtered diffraction data. The apparatus for acquiring raw diffraction data includes a collimated x-ray source having means for adjusting beam size and divergence of the x-ray generated, a 2-dimensional area detector for registering diffracted x-ray, and a sample motion assembly for moving the sample in the sample plane.Type: GrantFiled: June 19, 2001Date of Patent: April 19, 2005Assignee: HyperNex, Inc.Inventors: David S.

Patent number: 6792075Abstract: An apparatus and method for mapping film thickness of one or more textured polycrystalline thin films. Multiple sample films of known thickness are provided. Each sample film is irradiated by x-ray at a measurement point to generate a diffraction image that captures a plurality of diffraction arcs. Texture information (i.e., pole densities) of the sample film, is calculated based on incomplete pole figures collected on the diffraction image and used to correct the x-ray diffraction intensities from such sample. The corrected diffraction intensities are integrated for each sample film, and then used for constructing a calibration curve that correlates diffraction intensities with respective known film thickness of the sample films. The film thickness of a textured polycrystalline thin film of unknown thickness can therefore be mapped on such calibration curve, using a corrected and integrated diffraction intensity obtained for such thin film of unknown thickness.Type: GrantFiled: August 21, 2002Date of Patent: September 14, 2004Assignee: HyperNex, Inc.Inventors: Krzysztof J.

Patent number: 6301330Abstract: An apparatus and method for performing rapid, high-resolution polycrystalline crystallographic texture analysis, by calculating an Orientation Distribution Function (ODF) from partial pole figures obtained from x-ray diffraction measurements on large samples, e.g., 200 millimeter diameter wafers. The measurement apparatus includes a 2-D area x-ray detector and a collimated x-ray source arranged in a specific, fixed spatial relationship dependant on the properties of the sample to be measured, and also includes a particular wafer motion assembly. The wafer motion assembly includes three mutually orthogonal rectilinear translation stages, and a &phgr; rotation stage mounted thereon, as an uppermost motion stage, with its range restricted to 180° of rotation.Type: GrantFiled: July 30, 1999Date of Patent: October 9, 2001Assignee: HyperNex, Inc.Inventors: David S.

Patent number: 4783641Abstract: A uniform surface current density is approximated in an RF transmitting/receiving NMR coil by employing a plurality of discrete conductors having a resonantly distributed current. Inductive and capacitive lines provide a sinusoidal current distribution with various resonant modes providing different magnetic field orientations. The distributed current reduces losses. In a second order resonant mode, decoupling of the surface coil from a transmit coil is achieved without a blocking network.Type: GrantFiled: August 13, 1987Date of Patent: November 8, 1988Assignee: General Electric CompanyInventors: Cecil E.

Patent number: 4082951Abstract: A dosimetry technique for high-energy gamma radiation or X-radiation employs the Compton effect in conjunction with radiation-induced thermally activated depolarization phenomena. A dielectric material is disposed between two electrodes which are electrically short circuited to produce a dosimeter which is then exposed to the gamma or X radiation. The gamma or X-radiation impinging on the dosimeter interacts with the dielectric material directly or with the metal composing the electrode to produce Compton electrons which are emitted preferentially in the direction in which the radiation was traveling. A portion of these electrons becomes trapped in the dielectric material, consequently inducing a stable electrical polarization in the dielectric material.Type: GrantFiled: July 23, 1975Date of Patent: April 4, 1978Assignee: The United States of America as represented by the United States Department of EnergyInventor: Paul R. Moran

Patent number: 3955085Abstract: The present invention provides a method for tritium dosimetry. A dosimeter comprising a thin film of a material having relatively sensitive RITAC-RITAP dosimetry properties is exposed to radiation from tritium, and after the dosimeter has been removed from the source of the radiation, the low energy electron dose deposited in the thin film is determined by radiation-induced, thermally-activated polarization dosimetry techniques.Type: GrantFiled: July 23, 1975Date of Patent: May 4, 1976Assignee: The United States of America as represented by the United States Energy Research and Development AdministrationInventor: Paul R.
