  • Publication number: 20110025340
    Abstract: A semiconductor device analyzer comprises a function of radiating a charged particle beam on a sample and displaying a detected secondary electron image according to detected secondary electron intensity. A charged particle beam is radiated according to a first radiation pattern onto a semiconductor device that is to be analyzed, and a charge is injected. Next, a charge accumulation state of the semiconductor device that is to be analyzed is observed. A location where the charge accumulation state is abnormal can be detected as a defect location in the semiconductor device. A defect location is identified easily.

  • Publication number: 20080061234
    Abstract: Provided is an apparatus for acquiring information about the interior of a sample non-destructively and with high resolution, determining pass/fail of the sample and shortening inspection time. A sample is irradiated with an electron beam or X-rays, fluorescent X-rays from the sample are converted using a zone plate and are detected by a detector, an electric signal from the detector is converted to a digital signal by an A/D converter and the digital signal is applied to a fail decision unit, which determines pass/fail of the sample. If the sample is fail, an image processor applies image processing and presents a display on an image display unit.

  • Patent number: 6764099
    Abstract: In order to have an external force heading from the front toward the occupant received, a bumper member extending substantially along the length of the vehicle is disposed under or by the sides of the cabin (riding space). The shock absorbing members are connected at the rear ends of the bumper member. Even in the case of the vehicle in which it is difficult to dispose the shock absorbing member at the front portion of the vehicle within the range of the length of the vehicle for example, when an impact load is exerted to such a vehicle, the impact load may be efficiently absorbed. As a consequent the riding space for an occupant can be maintained. The shock absorbing body may be constructed of an upper shock absorbing member and a lower shock absorbing member. The upper and lower shock absorbing members may be formed of two types of members having different crushing features.

  • Patent number: 6188785
    Abstract: An image signal of a large number of patterns of the same shape on an LSI wafer obtained by an image sensor is held in a memory circuit, by using a CMOS image sensor chip incorporating a one-dimensional CMOS photodiode array, an analog-to-digital conversion circuit, a memory circuit and a processing circuit. Then, the image signal and one-cycle and two-cycle displaced image signals cyclically displaced from the image signal by the processing circuit are algebraically processed by a defect detection algorithm in the processing circuit of the CMOS image sensor. By this processing, a defect image is extracted without using a normal inspection pattern. Thus, a high-speed processing, a simplification of a configuration of an apparatus and a miniaturization of the apparatus become possible.

  • Patent number: 5949900
    Abstract: In a fine pattern inspection device for inspecting a fine pattern comprising a plurality of pattern elements which have the same form and which are formed on an inspection sample, the device detects a defect in the plurality of pattern elements by the use of an image derived from the fine pattern. An image obtaining unit obtains the image from the fine pattern and produces an image signal representing the image. The image signal is divided into first and second divided image signals. A processing unit extracts a defect image and an inverted defect image that is inverted in lightness of the defect image, by carrying out a first process that gives a predetermined delay to the first divided image signal and then inverts the lightness thereof to obtain a processed image signal and carrying out a second process that adds the processed image signal and the second divided image signal to obtain a difference image signal representing a difference image which includes the defect image and the inverted defect image.

  • Patent number: 5703492
    Abstract: In a fault analysis of large-scale integrated (LSI) circuits, a potential distribution image of a non-defective product and another potential distribution image of a defective product are displayed alternately and continuously in time, so that it is possible to acquire in real time an image of any location within a whole surface of the LSI chip. As a result, it can be viewed as if the potential distribution image of the non-defective product and the potential distribution image of the defective product are overlapped or superimposed with over time. Accordingly, a different portion between the non-defective and defective potential distribution images can be seen distinguishably from a coincident portion between the non-defective and defective potential distribution images, so that it is possible to trace the different portion in real time.
