Abstract
An emission microscope includes integrating and enhancing devices operating in parallel for optimizing the image of a scanned semiconductor device. Integration is terminated when sufficient clarity is acquired. The system further incorporates adaptive histogram matching using a noise distribution curve. Those pixels not meeting a predetermined intensity level are deleted to further enhance image display.
