The Hitachi S 3000 is a scanning electron microscope.[1]
An SEM generates a focused electron beam that is raster-scanned across the sample surface. Electrons interact with the sample, producing secondary electrons, backscattered electrons, and other signals that are collected to form an image. The magnification and resolution are controlled by the electron optics.
In a semiconductor fab, SEMs are used after various process steps such as lithography and etching to inspect pattern fidelity and detect defects. SEMs can be used in-line for rapid feedback or off-line for detailed analysis. Results inform process adjustments to maintain yield.
Common applications include critical dimension measurement, defect review, and contamination analysis. SEMs are also used for failure analysis and material characterization in research and development.
