Patent number: 8772732Abstract: Disclosed is a scanning charged particle beam apparatus equipped with an aberration corrector, contrived to eliminate resolution degradation in tilt observation by a chromatic third-order aperture aberration without relying on a specific optical system. A controller of the scanning charged particle beam apparatus provides a chromatic third-order aperture aberration measurement method relevant to tilt observation of a specimen. Further, the controller has a chromatic aberration control function relevant to tilt observation of a specimen. By means of the chromatic aberration control function, the controller controls a chromatic aberration to be positive or negative, rather than remaining at 0, in order to eliminate an image blur which occurs in a direction parallel to the specimen surface due to a chromatic third-order aperture aberration and a chromatic aberration at a tilt angle (t1) under observation and another tilt angle (?t1) axially opposite to the tilt angle.Type: GrantFiled: September 29, 2010Date of Patent: July 8, 2014Assignee: Hitachi High-Technologies CorporationInventors: Tomonori Nakano, Takeshi Kawasaki, Kotoko Hirose

Patent number: 8754664Abstract: The high magnification, high resolution and real-time property of an SEM image are realized when the electrical characteristics of an inspection object are measured, without affecting the electrical characteristics of the inspection object.

Next, a low-quality, low-magnification second image including the image of the target position in the inspection object on the sample and probe images is acquired. Next, data on the first image is built into the second image to generate an image for coarse-access observation which is the same in magnification as the second image.

Patent number: 8735808Abstract: A method of mass spectrometry is disclosed wherein a signal output from an ion detector is digitized by an Analogue to Digital Converter and is then deconvoluted to determine one or more ion arrival times and one more ion arrival intensities. The process of deconvoluting the ion signal involves determining a point spread function characteristic of an ion arriving at and being detected by the ion detector. A distribution of ion arrival times which produces a best fit to the digitised signal is then determined given that each ion arrival is assumed to produce a response given by the point spread function. A plurality of ion arrival times are then combined to produce a composite ion arrival time-intensity spectrum.Type: GrantFiled: February 14, 2011Date of Patent: May 27, 2014Assignee: Micromass UK LimitedInventors: Richard Denny, Keith Richardson, Martin Raymond Green, Steven Derek Pringle, Anthony James Gilbert, John Skilling, Jason Lee Wildgoose

Patent number: 8704173Abstract: Devices and methods for the acquisition of mass spectra with very high mass resolution in ion cyclotron resonance mass spectrometers include cylindrical ICR measuring cells with special electrode geometries to generate harmonic trapping potentials for orbiting ions. The sheath of the cylindrical cell is divided by longitudinal gaps into a multitude of sheath electrodes, which either have to carry layers with resistance profiles able to generate parabolic voltage profiles along the sheath electrodes, or which form sheath electrodes of varying width by parabolic gaps. Orbiting ions of a given mass m/z oscillate harmonically in an axial direction with the same frequency, independent of the radius of their orbit and their oscillation amplitude. Ideally, the cylinders are closed by endcaps with rotationally hyperbolic form, divided into partial electrodes. The ions are excited by dipolar excitation fields. The orbiting ion clouds are kept together for much longer periods than was possible hitherto.Type: GrantFiled: September 17, 2010Date of Patent: April 22, 2014Assignee: Bruker Daltonik GmbHInventors: Evgenij Nikolaev, Ivan Boldin, Jochen Franzen
