  • Patent number: 8466990
    Abstract: An imaging apparatus includes: an imaging unit configured to image an image using an imaging device; an image obtaining unit configured to obtain a plurality of images equivalent to the time of dark, imaged by the imaging unit; a registering unit configured to register, with an image obtained by the image obtaining unit, the address and change amount of a pixel where the output value of the pixel changes so as to exceed a predetermined threshold; and a correcting unit configured to correct, when taking a pixel corresponding to an address registered by the registering unit as a processing object pixel, the pixel value of the processing object pixel based on comparison between difference of the output values of the processing object pixel and a peripheral pixel of the processing object pixel, and the change amount of the processing object pixel.

  • Patent number: 6605512
    Abstract: The invention provides a non-destructive inspection method for a selectively grown film and a manufacturing method of a semiconductor device for providing a simple and convenient process control and throughput improvement. The method comprises forming a pattern in which selectively grown areas are closely arranged on a wafer for manufacturing an LSI, determining the film thickness and the composition of the selectively grown layer by analyzing optical constant data for the entire pattern, and feeding back the result to the next batch thereby conducting process control.

  • Patent number: 5387545
    Abstract: An impurity diffusion method which can control a surface atomic concentration from a low to a high surface atomic concentration with a good uniformity is provided. Natural oxide is removed from the surface of a semiconductor substrate with a deoxidizing atmosphere gas as a diffusion atmosphere gas in advance, and then an impurity gas is passed thereto, while passing the deoxidizing atmosphere gas thereto, thereby conducting the diffusion. Flow rate or concentration of impurity of the impurity gas is so set that the impurity atomic concentration of the diffusion layer can be controlled by the flow rate or the concentration of impurity of the impurity gas. The impurity atomic concentration of the diffusion layer can be controlled by adjusting the flow rate or concentration of impurity of the impurity gas, and a diffusion layer having a low impurity atomic concentration can be formed. A shallow junction having a depth of not more than 50 nm can be formed.
