Quantitative X-ray analysis—ratio correction
A method of X-ray analysis measures X-ray diffraction in transmission. In order to carry out quantitative measurements, a background measurement is taken slightly away from the diffraction peak and the ratio of measured intensities used to correct for variations in sample composition.

MULTI-ELECTRON BEAM INSPECTION DEVICE AND MULTI-ELECTRON BEAM INSPECTION METHOD
A multi-electron beam inspection apparatus includes a multi-detector that includes a plurality of detection sensors each of which detects a secondary electron beam emitted due to that a target object is irradiated with a primary electron beam individually preset in multiple secondary electron beams emitted because the target object is irradiated with multiple primary electron beams, a reference image data generation circuit that generates reference image data of a position irradiated with each primary electron beam, based on design data serving as a basis of the pattern formed on the target object, a synthesis circuit that synthesizes, for each primary electron beam, the reference image data of the position irradiated with a primary electron beam concerned and portions of reference image data of positions irradiated with other primary electron beams different from the primary electron beam concerned, and a comparison circuit that compares synthetic reference image data having been synthesized, and secondary electron image data based on a value detected by the detection sensor which detects a secondary electron beam due to irradiation with the primary electron beam concerned.
Pattern measurement device and computer program for evaluating patterns based on centroids of the patterns
The purpose of the present invention is to provide a pattern measurement device for quantitatively evaluating a pattern formed using a directed self-assembly (DSA) method with high accuracy. The present invention is a pattern measurement device for measuring distances between patterns formed in a sample, wherein the centroids of a plurality of patterns included in an image are determined; the inter-centroid distances, and the like, of the plurality of centroids are determined; and on the basis of the inter-centroid distances, and the like, of the plurality of centroids, a pattern meeting a specific condition is distinguished from patterns different from the pattern meeting the specific condition or information is calculated about the number of the patterns meeting the specific condition, the size of an area including the patterns meeting the specific condition, and the number of imaginary lines between the patterns meeting the specific condition.
X-RAY BIOPSY SPECIMEN IMAGER AND METHODS
Methods and devices are disclosed for the tomographic imaging of a biological sample from almost all rotational perspectives in three-dimensional space and with multiple imaging modalities. A biological sample is positioned on an imaging stage that is capable of nearly full 360-degree rotation in at least one of two substantially orthogonal axes. Positioned about the stage is an X-ray imaging module enabling the recording of a series of images. A reflected light imaging module can also be positioned about the stage to enable recording of black and white or color white light images. A computer can use the images to construct three-dimensional models of the sample and to render images of the sample conveying information from one or more imaging channels.
Inspection system and method
An inspection system includes one or more processors and an infrared (IR) camera operably coupled to the one or more processors. The one or more processors control a microwave transmitter to sequentially emit microwaves having different frequencies within a designated frequency range into an object during a first sweep. The IR camera generates thermal image data of the object after the object is heated by each of the different frequencies of microwaves. The one or more processors analyze the thermal image data and determine a selected frequency within the designated frequency range that provides greater heating of the object than one or more other frequencies in the designated frequency range. The one or more processors also analyze select thermal image data of the object, responsive to heating of the object by the selected frequency of microwaves, to detect an element in the object.
