    摘要: The material strength of extensive objects can be determined efficiently by using two distance measurers, wherein a first distance measurer determines the distance to a first main surface of the object and a second distance measurer determines the distance to a second main surface object opposing the first main surface. If potential measurement errors due to the extensive geometry are avoided by determining a reference distance between the first distance measurer and the second distance measurer by a reference unit via X-radiation, the thickness of the object between the first main surface and the second main surface can be determined with high accuracy and velocity.

    摘要: A digital radiography imaging system for acquiring digital images of an object, and a method for transforming digital images into an absolute thickness map characterizing the object under inspection. The system includes a radiation source for directing radiation through a desired region of the object, and a radiation detector having a plurality of sensing elements for detecting radiation passing through the object. Numerical data generated from each sensing element is calibrated, for example by correcting for variations in radiation paths between the source and detector, by correcting for variations in the spatial frequency response (MTF) of the detector, by correcting for variations in the geometric profile of the object under inspection, and by correcting for material contained in and/or around the object. The calibrated data is processed in order to generate and display an absolute thickness map of the object. The calibration procedures are adapted for extracting a thickness map from both isotope sources and X-ray tube sources.

    摘要: A metrology system and method for measuring the thickness of thin-films of semiconductor wafer. This system and method analyze x-ray reflectivity data to determine transmission characteristics of thin-film layers. Based on these transmission characteristics the thickness of the thin-layer can be determined. Unlike some prior systems and methods, the system and method herein does not determine the thickness of the thin-film layer based on a fringe pattern in reflectivity for the thin-film layer. The fact that the system and method herein does not rely the fringe pattern is particularly advantageous in situations where the thin-film layer is of thickness which makes it very difficult to resolve the fringe pattern in the reflectivity data.

    摘要: Inspection of objects such as X-ray lithography masks is carried out by passing X-rays or extreme ultraviolet light through an object which absorbs in a pattern to provide a patterned X-ray or ultraviolet image which is then directed to a converter. The converter converts the image incident upon it to an image formed by electrons emitted from the converter. The emitted electrons are magnified in an electron microscope and the magnified electron image is displayed by the electron microscope. The visible image may be further digitized and processed by a computer, including long-term storage or display on a computer monitor. X-ray lithography masks may be inspected by passing X-rays through masks of the same type that will be used for lithography so that the magnified image of the X-rays passed through the masks corresponds to the pattern of X-rays that will be incident on a photoresist, allowing accurate inspection of X-ray masks before use.

    摘要: An apparatus and method for controlling the quality of cylindrical or other geometrically regular-shaped products, such as tube or rounds, through high precision, continuous, real-time three-dimensional analysis of hot or cold products during their manufacture are disclosed. The apparatus includes multiple penetrating radiation sources and detectors. The apparatus is able to continuously and in real time perform a three-dimensional analysis of hot or cold products, detect cross-sectional and longitudinal flaws in the products, determine the processing steps causing the flaw, and modify the production process through feedback and/or feedforward control of the processing equipment. In performing the analysis on hot or cold products, the apparatus can determine the dimensional measurements of the products at other temperatures and take these measurements into consideration while controlling the manufacturing process in order to produce products of consistent dimensional quality.

    摘要: A device for continuously measuring the thickness of a foil includes a radiation source opposite a radiation detector, and a movement member which moves the radiation source and detector synchronously in a width-direction of the foil. A signal generator generates a signal indicating a position of a portion of the foil whose thickness is being measured, and a counter having a plurality of integrating channels integrates detection signals output from the detector to generate an integrated count number for each channel. A signal switching member switches each of the plurality of integrating channels of the counter according to signals generated by the signal generator, and a calculator calculates a foil thickness from the integrated counted number for each channel of the counter. This structure allows continuous and precise measurement of the foil's thickness.
