Abstract
Solutions of the stationary and time-dependent equations of diffusion are presented for contamination when scanning a rectangular area in th e scanning electron microscope (SEM). A method is described to record the thickness of the contamination layer by the signal of secondary or backscattered electrons and to measure the influence of electron curr ent density, beam energy, and specimen cooling on the contamination ra te.
