Patents by Inventor Ruth Shewmon Bloom

Ruth Shewmon Bloom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12080514
    Abstract: A device may include an electron source, a detector, and a deflector. The electron source may be directed toward a sample area. The detector may receive an electron signal or an electron-induced signal. A deflector may be positioned between the electron source and the sample. The deflector may modulate an intensity of the electron source directed to the sample area according to an electron dose waveform having a continuously variable temporal profile.
    Type: Grant
    Filed: May 24, 2023
    Date of Patent: September 3, 2024
    Assignee: INTEGRATED DYNAMIC ELECTRON SOLUTIONS, INC.
    Inventors: Ruth Shewmon Bloom, Bryan Walter Reed, Daniel Joseph Masiel, Sang Tae Park

  • Patent number: 11676796
    Abstract: A charged particle beam device including: a charged particle beam source which emits a charged particle beam; a blanking device which has an electrostatic deflector that deflects and blocks the charged particle beam; an irradiation optical system which irradiates a specimen with the charged particle beam; and a control unit which controls the electrostatic deflector, the control unit performing processing of: acquiring a target value of a dose of the charged particle beam for the specimen; setting a ratio A/B of a time A during which the charged particle beam is not blocked to a unit time B (where A?B, A?0), based on the target value; and operating the electrostatic deflector based on the ratio.

  • Publication number: 20230072991
    Abstract: A charged particle beam device scans a specimen with a charged particle beam and generates an image based on a detected signal from a detector that detects a signal generated from the specimen based on the scan performed by the charged particle beam. The charged particle beam device includes: a blanker that performs blanking of the charged particle beam; an image acquisition unit that acquires a plurality of images by controlling the blanking during the scan performed by the charged particle beam, the plurality of images including pixels corresponding to a region of the specimen that is irradiated with the charged particle beam and pixels corresponding to a region of the specimen that is not irradiated with the charged particle beam; and an integrated image generation unit that generates an integrated image by integrating the plurality of acquired images.
