  • Patent number: 8704161
    Abstract: Disclosed is a quadrupole mass spectrometer, which is capable of, during an SIM measurement, maximally reducing a settling time-period necessary for an operation of changing an input voltage to a quadrupole mass filter in a staircase pattern, and preventing unwanted ions from excessively entering a detector during a course of changing between a plurality of mass values. Under a condition that a response speed of a DC voltage U to be applied to quadrupole electrodes is less than that of an amplitude of a high-frequency voltage V, a control section 10 is operable to rearrange the mass values in descending order of mass value, and an optimal settling-time calculation sub-section 101 is operable to determine a settling time-period for each of the mass values, based on a mass-value difference and a post-change mass value.

  • Patent number: 8692214
    Abstract: An imaging method and apparatus for forming images of substantially the same area on a sample for defect inspection within the area are disclosed. The disclosed method includes line-scanning the charged particle beam over the area to form a plurality of n*Y scan lines by repeatedly forming a group of n scan lines for Y times. During the formation of each group of n scan lines, an optical beam is, from one line scan to another, selectively illuminated on the area prior to or simultaneously with scanning of the charged particle beam. In addition, during the formation of each group of n scan lines, a condition of illumination of the optical beam selectively changes from one line scan to another. The conditions at which individual n scan lines are formed are repeated for the formation of all Y groups of scan lines.

  • Patent number: 8686380
    Abstract: The present invention provides a charged particle beam apparatus that keeps the degree of vacuum in the vicinity of the electron source to ultra-high vacuum such as 10?8 to 10?9 Pa even in the state where electron beams are emitted using a non-evaporable getter pump and is not affected by dropout foreign particles. The present invention includes a vacuum vessel in which a charged particle source (electron source, ion source, etc.) is disposed and a non-evaporable getter pump disposed at a position that does not directly face electron beams and includes a structure that makes the non-evaporable getter pump upward with respect to a horizontal direction to drop out foreign particles into a bottom in a groove, so that the foreign particles dropped out from the non-evaporable getter pump do not face an electron optical system.

  • Patent number: 8680479
    Abstract: An ion entrance opening (15) for introducing ions into an orbit (C) along a sector-shaped electric field entrance optical axis (A) from outside is provided in an outer electrode (11a) of a main electrode (11) for producing a sector-shaped electric field for forming the orbit (C). In order to correct the disturbance in the sector-shaped electric field due to the provision the ion entrance opening (15), three electrode correction electrodes (20) are aligned in the direction of the sector-shaped electric field entrance optical axis (A). By appropriately adjusting each of the direct-current voltages applied to the electrode correction electrodes (20), the equipotential lines in the sector-shaped electric field can be substantially the same as in the case where the ion entrance opening (15) is not provided. This configuration can alleviate the shift of the orbit of ions flying along the orbit (C).

  • Patent number: 8674326
    Abstract: A patient platform for making the position and posture of a diseased site coincide with those established by a treatment plan. Translation units translate a top board in the X, Y and Z directions respectively, in a fixed coordinate system. Rotation units rotate the top board in the ?, ?, and ? directions respectively. A controller controls the translation units and rotation units, based on desired rotation center point and desired rotation angle. The controller has a rotation drive signal generation unit that generates a signal for moving the top board in a rotating manner from the reference state “a” of the translation units and the rotation units to a desired rotation angle; and a translation drive signal generation unit that generates a signal for translating the translation units so the amount of translation movement, of the desired rotation center point, caused by the rotation movement is a predetermined value.

  • Patent number: 8669517
    Abstract: A method and apparatus is provided for reducing unwanted isotopes of an ion implantation species from an ion beamline. The apparatus herein disclosed is a mass analysis variable exit aperture that selectively reduces the size of an exit aperture as seen by an ion beam. In one embodiment, the variable mass analysis exit aperture is located within a mass analyzer at a position upstream of a resolving aperture and effectively limits the size of an exit aperture so as to allow passage of desired implantation isotope(s) while blocking the passage of unwanted implantation isotopes. In one particular embodiment, the mass analysis variable exit aperture has a mechanical drive mechanism that enables a blocking structure to be moved into the path of an ion beam in a graduated fashion as guided by a control unit that operates based upon one or more characteristics of the ion beam.

  • Patent number: 8661560
    Abstract: A microwave probe having a metal tip on the free end of a microcantilever. In one embodiment, a pyramidal pit is isotropically etched in a device wafer of monocrystalline silicon. Oxidation may sharpen the pit. Deposited metal forms the metal tip in the pit and a bottom shield. Other metal sandwiched between equally thick dielectric layers contact the tip and form a conduction path along the cantilever for the probe and detected signals. Further metal forms a top shield overlying the conduction path and the dielectrically isolated tip and having equal thickness to the bottom shield, thus producing together with the symmetric dielectric layers a balanced structure with reduced thermal bending. The device wafer is bonded to a handle wafer. The handle is formed and remaining silicon of the device wafer is removed to release the cantilever.
