Overview:

Changes in DC magnetic field levels near an electron microscope or e-beam lithography tool degrade image quality and inhibit production. A change in DC fields often results in image distortion, a blurred image, or image drift. Common sources of change in DC fields are variation in the Earth’s magnetic field and the movement ……
