摘要: Provided are methods to improve tomography by creating fiducial holes using charged particle beams, and using the fiducial holes to improve the sample positioning, acquisition, alignment, reconstruction, and visualization of tomography data sets. Some versions create fiducial holes with an ion beam during the process of milling the sample. Other versions create in situ fiducial holes within the TEM using the electron beam prior to acquiring a tomography data series. In some versions multiple sets of fiducial holes are made, positioned strategically around a region of interest. The fiducial holes may be employed to properly position the features of interest during the acquisition, and later to help better align the tilt-series, and improve the accuracy and resolution of the final reconstruction. The operator or software may identify the holes to be tracked with tomography feature tracking techniques.

摘要: A method and apparatus for imaging a specimen using a scanning-type microscope, by irradiating a specimen with a beam of radiation using a scanning motion, and detecting a flux of radiation emanating from the specimen in response to the irradiation, in the first sampling session {S1} of a set {Sn}, gathering data from a first collection of sparsely distributed sampling points {P1} of set {Pn}. A mathematical registration correction is made to compensate for drift mismatches between different members of the set {Pn}, and an image of the specimen is assembled using the set {Pn} as input to an integrative mathematical reconstruction procedure.

摘要: The invention provides a method for providing an Au-containing layer onto a surface of a work piece, which method comprises: providing 510 a deposition fluid comprising Au(CO)Cl; depositing 520 the fluid on at least part of the surface of the work piece; and directing 530 a charged particle beam toward the surface of the work piece onto which at least part of the fluid is deposited to decompose Au(CO)Cl thereby forming the Au-containing layer on the surface of the work piece. By using Au(CO)Cl as a precursor for charged particle induced deposition, a gold Au layer may be deposited with a very high purity compared to methods known in the art.

摘要: A microscope has an objective, a light source illuminating a sample over an illumination beam path, an arrangement producing a flat illumination pattern which is structured in both spatial directions on the sample, a surface detector detecting light coming over one picture beam path, an arrangement shifting the illumination pattern on the sample in one displacement direction, and a control unit taking one picture at a time of the light which was detected by the detector as phase picture in different positions of the pattern along the displacement direction and to computationally reconstruct from these phase pictures an overall picture of the illuminated sample region. The displacement direction is oblique to the main axes of symmetry of the illumination pattern and depending on the illumination pattern is chosen such that the number of phase pictures which is necessary for the picture reconstruction corresponds to the theoretically minimally required value.

摘要: A method of mitigating the effects of environmental pressure variation while using a charged particle microscope is described. The charged particle microscope equipped with a barometric pressure sensor and an automatic controller configured to use the signal from the barometric sensor as an input to a control procedure to compensate for a relative positional error between the charged particle beam and the specimen holder.

摘要: The invention relates to a compound objective lens for a Scanning Electron Microscope having a conventional magnetic lens excited by a first lens coil, an immersion magnetic lens excited by a second lens coil, and an immersion electrostatic lens excited by the voltage difference between the sample and the electrostatic lens electrode. For a predetermined excitation of the lens, the electron beam can be focused on the sample using combinations of excitations of the two lens coils. More BSE information can be obtained when the detector distinguishes between BSE's (202) that strike the detector close to the axis and BSE's (204) that strike the detector further removed from the axis. By tuning the ratio of the excitation of the two lens coils, the distance from the axis that the BSE's impinge on the detector can be changed, and the compound lens can be used as an energy selective detector.

摘要: The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.
