  • Patent number: 9165742
    Abstract: Embodiments of the present disclosure are directed to an electron beam imaging/inspection apparatus having an electron source device to direct flood electrons on a sample immediately before image acquisition or inspection. The apparatus comprises a first device configured to charge a sample in a first mode, wherein the first device includes an electron source configured to provide a flood beam of charged particles to a first area of the sample. The apparatus also comprises a second device configured to generate a primary beam of electrons and characterize an interaction between the primary beam and a second area of the sample within the first area in a second mode. The apparatus is configured to switch from the first mode to the second mode less than 1 second.

  • Publication number: 20150144785
    Abstract: An electron beam device for inspecting a target substrate or specimen thereon includes a beam separator with an asymmetric quadrupole electrostatic deflector for improving field uniformity for a single direction of deflection. The asymmetric quadrupole electrostatic deflector includes two orthogonal electrode plates spanning roughly 60 degrees and two electrode plates spanning roughly 120 degrees, the two latter plates defining a unidirectional deflection field. The device generates a primary electron beam and focuses the primary electron beam along an optical axis into the target substrate. Secondary electrons detected at the target substrate are focused into a secondary electron beam. The beam separator with asymmetric quadrupole electrostatic deflector deflects the secondary electron beam away from the axis of the primary electron beam in the direction of deflection and into a detector array.

  • Publication number: 20150123542
    Abstract: An apparatus may include a substrate support portion, a plasma generation chamber, electrodes, and a power source. The substrate support portion supports a substrate including an insulating layer and a substrate bulk. The plasma generation chamber may include chamber wall portions, a gas port, and a plasma application aperture and is configured to contain a gas. The plasma application aperture may be covered by a portion of the substrate. Each electrode may protrude into or extend into an interior portion of the plasma generation chamber. The power source may be coupled to a particular electrode, and the power source may be configured to apply a voltage to the particular electrode. Application of the voltage to the particular electrode generates a plasma within the plasma generation chamber, whereby generation of the plasma results in a conductive path through the insulating layer of the substrate between the plasma and the substrate bulk.

  • Publication number: 20120004127
    Abstract: One example embodiment includes a method of preparing a personalized genomics profile for a patient with colorectal cancer. The method includes assaying an expression level of an RNA transcript in a biological sample. The biological sample includes a colorectal cancer cell obtained from a patient. The method also includes determining a normalized expression level of the RNA transcript, wherein the normalized expression level of the RNA transcript correlates with an increased likelihood of colorectal cancer recurrence in the patient. The method further includes creating a report. The report summarizes the data obtained from the normalized expression level and includes an estimate of likelihood of long-term survival without colorectal cancer recurrence in said patient.

  • Publication number: 20050204480
    Abstract: An apparatus and method for an improved washing machine having a tilt-out laundry assembly. The tilt-out action is achieved by a tiltable joint between the side of the laundry assembly and front standing struts. The tiltable joint permits a laundry assembly to rotate about the front standing struts once rear struts are removed from the rear side of the laundry assembly. In use, the service person removes the rear struts, tilts the laundry assembly about the front standing struts, and then removes the laundry assembly from the cabinet.
