    摘要: During closer inspection with a local defect area being magnified, it is desirable to reduce image acquisition time by making the number of stage moves as few as possible so that a defect can be observed efficiently. To accomplish this, the invention offers a method of observing samples characterized by: acquiring a reference sample image not including any defect on a sample by capturing an image of the sample, based on the information on the defect developed on the sample and detected by an inspection apparatus; adjusting the position of the sample so that the defect will fall within the field of view of image capture, based on the above information; acquiring a defective sample image including the defect on the sample by capturing an image of the sample in the adjusted position; locating the defect on the defective sample image by comparing the reference sample image and the defective sample image; acquiring a magnified image of the defect by capturing a magnified view of the local area where the located defect exists within the field of view of image capture; and displaying the magnified image of the defect on a screen.

    摘要: A slice selection gradient magnetic field used in a pulse sequence for generating a spin echo signal is applied in such a fashion that its polarity at the time of a 90.degree. pulse becomes opposite to the one at the time of 180.degree. pulse, in order to expand a dynamic range of blood flow speed measurement. When the blood flow speed contains a component in a slice vertical direction, the gradient magnetic field in the slice vertical direction is adjusted so that the phase changes of two sets of flow encoded pulses contained in the slice vertical direction are opposite to each other.The flow speed in the direction of the readout gradient magnetic field, which is a lateral direction of the slice plane, is purely measured by canceling influences of the flow in the slice vertical direction.

    摘要: An operator-free and fully automated semiconductor inspection system with high throughput is realized. All conditions required for capturing and inspection are generated from design information such as CAD data. In order to perform actual inspection under the conditions, a semiconductor inspection system is composed of a navigation system for generating all the conditions required for capturing and inspection from the design information and a scanning electron microscope system for actually performing capturing and inspection. Moreover, in the case of performing a matching process between designed data and a SEM image, deformed parts are corrected by use of edge information in accordance with multiple directions and smoothing thereof. Furthermore, a SEM image corresponding to a detected position is re-registered as a template, and the matching process is thereby performed.
