Publication number: 20240105721Abstract: Devices with increased susceptibility to ionizing radiation feature multiple parasitic transistors having leakage currents that increase with total ionizing dose (TID) due to negative threshold shifts from radiation-induced charge buildup in the field oxide. Leakage currents of parasitic edge transistors associated with active region sidewalls under a gate are enhanced using branching gate patterns that increase the number of these sidewalls. Other variations combine parasitic edge transistors with parasitic field transistors formed under the field oxide between active regions, or between n-wells and active regions. Arrays of such devices connected in parallel further multiply leakage currents, while novel compact designs increase the density and hence the sensitivity to TID for a given circuit area.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Applicant: Apogee Semiconductor, Inc.Inventors: Emily Ann Donnelly, Mark Hamlyn, Kyle Schulmeyer, Gregory A.

Patent number: 11169029Abstract: An optical pyrometer having a coaxial light guide delivers laser radiation through optics to heat a localized area on a sample, and simultaneously collects optical radiation from the sample to perform temperature measurement of the heated area. Inner and outer light guides can comprise the core and inner cladding, respectively, of a double-clad fiber (DCF), or can be formed using a combination of optical fibers in one or more coaxial bundles. Coaxial construction and shared optics facilitate alignment of the centers of the heated and observed areas on the sample. The heated area can be on the order of micrometers when using a single-mode optical fiber core as the inner light guide. The system can be configured to heat small samples within a vacuum system of charged-particle beam microscopes such as electron microscopes. A method for using the invention in a microscope is also provided.Type: GrantFiled: August 26, 2019Date of Patent: November 9, 2021Assignee: Waviks, Inc.Inventors: Gregory A. Magel, Thomas M. Moore

Patent number: 10176963Abstract: Apparatus and methods for the alignment of a charged-particle beam with an optical beam within a charged-particle beam microscope, and to the focusing of the optical beam are disclosed. An embodiment includes a charged-particle beam microscope having one or more charged-particle beams, such as an electron beam, and one or more optical beams provided by an optical-beam accessory that is mounted in or on the charged-particle beam microscope. This accessory is integrated into a nanomanipulator system, allowing its focus location to be moved within the microscope. The apparatus includes a two-dimensional pixelated beam locator such as a CCD or CMOS imaging array sensor. The image formed by this sensor can then be used to manually, or automatically in an open or closed loop configuration, adjust the positioning of one or more charged-particle beams or optical beams to achieve coincidence of such beams or focus of one or more such beams.Type: GrantFiled: December 8, 2017Date of Patent: January 8, 2019Assignee: Waviks, Inc.Inventors: Thomas M.

Patent number: 8440969Abstract: This disclosure relates to a method and apparatus for producing multiple pixel-by-pixel simultaneous and overlapping images of a sample in a microscope with multiple imaging beams. A scanning electron microscope, a focused ion-beam microscope, or a microscope having both beams, also has an optical microscope. A region of interest on a sample is scanned by both charged-particle and optical beams, either by moving the sample beneath the beams by use of a mechanical stage, or by synchronized scanning of the stationary sample by the imaging beams, or by independently scanning the sample with the imaging beams and recording imaging signals so as to form pixel-by-pixel simultaneous and overlapping images.Type: GrantFiled: August 2, 2011Date of Patent: May 14, 2013Assignee: Omniprobe, Inc.Inventors: Thomas M.

Patent number: 8306075Abstract: A system and method for optical frequency conversion having asymmetric output include a coherent light apparatus. The coherent light apparatus includes a coherent light source that produces a first coherent light, a frequency converter optically coupled to the coherent light source, and a coupling optic optically coupled between the coherent light source and the frequency converter. The frequency converter converts the first coherent light to a second coherent light at a second frequency and includes an asymmetric frequency converter (AFC) that nonlinearly converts the first coherent light to the second coherent light with the frequency conversion being more efficient in a first direction than in a second direction. A resonant cavity formed about the AFC circulates the first coherent light and transmits the second coherent light propagating in the first direction.Type: GrantFiled: April 18, 2011Date of Patent: November 6, 2012Assignee: Texas Instruments IncorporatedInventor: Gregory A.
