| 20090133167 | METHOD FOR OBTAINING A SCANNING TRANSMISSION IMAGE OF A SAMPLE IN A PARTICLE-OPTICAL APPARATUS - A method for improving the resolution of STEM images of thick samples. In STEM, the diameter of the cross-over depends on the opening half-angle α of the beam and can be as low as 0.1 nm. For optimum resolution an opening half-angle is chosen at which the diameter of the cross-over R(α) shows a minimum. For thick samples the resolution is, for those parts of the sample removed from the cross-over plane, limited by the convergence of the beam, resulting in a diameter D of the beam at the surface of the sample. The opening angle is chosen to balance the contribution of convergence and of diameter of the cross-over by choosing an opening half-angle smaller than the optimum opening half-angle. Effectively the sample is then scanned with a beam that has a substantially constant diameter over the length of the sample material through which the electrons have to travel. | 05-21-2009 |
| 20100148064 | X-RAY DETECTOR FOR ELECTRON MICROSCOPE - Multiple detectors arranged in a ring within a specimen chamber provide a large solid angle of collection. The detectors preferably include a shutter and a cold shield that reduce ice formation on the detector. By providing detectors surrounding the sample, a large solid angle is provided for improved detection and x-rays are detected regardless of the direction of sample tilt. | 06-17-2010 |

| 20100032567 | Method of Machining a Work Piece with a Focused Particle Beam - The invention relates to a method for producing high-quality samples for e.g. TEM inspection. When thinning samples with e.g. a Focused Ion Beam apparatus (FIB), the sample often oxidizes when taken from the FIB due to the exposure to air. This results in low-quality samples, that may be unfit for further analysis. By forming a passivation layer, preferably a hydrogen passivation layer, on the sample in situ, that is: before taking the sample from the FIB, high quality. | 02-11-2010 |
