摘要： A multi-beam apparatus for inspecting or processing a sample (232) with a multitude of focused beams, the apparatus equipped to scan a multitude of N beams (240-n) over the sample, the apparatus equipped with a multitude of M detectors (234-m) for detecting secondary radiation emitted by the sample when said sample is irradiated by the multitude of beams, each of the detectors capable of outputting a detector signal representing the intensity of the secondary radiation detected by the detector, , in working, each detector signal comprising information caused by multiple beams, the information caused by one beam thus spread over multiple detectors, the apparatus equipped with a programmable controller (236) for processing the multitude of detector signals to a multitude of output signals, using weight factors so that each output signal represents information caused by a single beam, characterized in that the weight factors are dynamic weight factors depending on the scan position of the beams with respect to the detectors and the distance between sample and detectors.
The weight factors describe the contribution of each beam to each detector. The invention is based on the insight that when scanning the beams over the sample, the position of the position where the secondary radiation is formed (the impact position) changes. Therefore the weight factors should be a function of the scan position.
Also the distance between sample and detector (the working distance) has a similar effect on the weight factors
It is noted that, as the position of the impact is known at all times the weight factors can be a known function of the scan position, working distance and, if applicable, the beam energies.

摘要： The method relates to a method of scanning a sample. Scanning a sample is typically done by scanning the sample with a probe along a multitude of parallel lines. In prior art scan methods a sample is scanned multiple times with a nominally identical scan pattern. The invention is based on the insight that the coherence between adjacent points in a direction along the scan direction is much better than the coherence of adjacent points perpendicular to the scan direction. By combining two images that are scanned perpendicular to each other, it should thus be possible to form an image making use of the improved coherence (due to shorter temporal distance) in both directions. The method thus involves scanning the sample with two scan patterns, the lines of one scan pattern preferably perpendicular to the lines of the other scan pattern. Hereby it is possible to use the temporal coherence of scan points on a line of one scan pattern to align the lines of the other scan pattern, and vice versa.
摘要翻译：该方法涉及扫描样本的方法。通常通过沿着多条平行线用探针扫描样品来扫描样品。在现有技术的扫描方法中，用标称相同的扫描图案多次扫描样品。本发明基于以下认识：沿着扫描方向的方向上的相邻点之间的相干性比垂直于扫描方向的相邻点的相干性好得多。通过组合彼此垂直扫描的两个图像，因此应该能够在两个方向上利用改善的相干性（由于更短的时间距离）而形成图像。因此该方法涉及用两种扫描图案扫描样品，一种扫描图案的线优选垂直于另一种扫描图案的线。由此可以使用一个扫描图案的线上的扫描点的时间相干性来对齐另一个扫描图案的线，反之亦然。

摘要： Methods and systems are provided for a scanning microscope to rapidly form a partial digital image of an area. The method includes performing an initial scan for the area and using initial scan to identify regions representing features of interest in the area. Then, the method performs additional adaptive scans of the regions representing structures of interest. Such scans adapt the path of the scanning beam to follow the edges of a feature of interest by performing localized scan patterns that intersect the feature edge, and directing the localized scan patterns to follow the feature edge.

摘要： The invention relates to a method for analyzing the output signal of a Silicon Drift Detector (SDD). A SDD is used for detecting X-rays in e.g. Scanning Electron Microscopes and X-ray analysis instruments, where X-rays are emitted by a sample as a result of impinging radiation.
The signal of a SDD comprises a number of randomly spaced steps, in which the step height is a function of the energy of the detected X-ray photon.
The variance in step height is a function of the averaging time that can be used to determine the plateau between steps: averaging over a short interval (405) results in more uncertainty of the plateau value than a long interval (403). As the step height relies on determination of the preceding plateau and the following plateau value, step heights (401, 402) have different reliabilities/variances. By according a weight factor, the weight factor a function of the variance such that a step with a low variance (high reliability) is associated with a larger weight factor than a step with a high variance (low reliability), measurement values with a low variance, corresponding to a high reliance, are emphasized. This results in better resolved spectra.

摘要： A detector system for a transmission electron microscope includes a first detector for recording a pattern and a second detector for recording a position of a feature of the pattern. The second detector is preferably a position sensitive detector that provides accurate, rapid position information that can be used as feedback to stabilize the position of the pattern on the first detector. In one embodiment, the first detector detects an electron energy loss electron spectrum, and the second detector, positioned behind the first detector and detecting electrons that pass through the first detector, detects the position of the zero-loss peak and adjusts the electron path to stabilize the position of the spectrum on the first detector.

摘要： A pixelated CMOS radiation sensor (3) (e.g. in a 4T pinned photodiode device) that comprises a layered structure including:
- A p-type Si substrate (5);
- An n-doped region within said substrate (7);
- A p + -doped layer (9) that overlies said n-doped region;
- An SiO x layer (11) that overlies said p + -doped layer,

in which a Boron film (13) is deposited between said p + -doped layer and said SiO x layer. Application of such a (pure) Boron film serves to reduce leakage current by one or more orders of magnitude. Even a relatively thin Boron film (e.g. thickness 1-2 nm) can produce this effect.
