Transmission Electron Microscopy (TEM) Techniques for Semiconductor Failure Analysis

Abstract This presentation shows how transmission electron microscopy (TEM) is used in semiconductor failure analysis to locate and identify defects based on their physical and elemental characteristics. It covers sample preparation methods for planar, cross-sectional, and elemental analysis, reviews the capabilities of different illumination and imaging modes, and shows how beam-specimen interactions are employed in energy dispersive (EDS) and electron energy loss spectroscopy (EELS). It describes the various ways transmission electron microscopes can be configured for elemental analysis and mapping and reviews the advantages of scanning TEM (STEM) approaches. It also provides an introduction to energy-filtered TEM (EFTEM) and how it compares with other TEM imaging techniques.
