EVO 60 XVP

The Zeiss EVO 60 XVP is a scanning electron microscope (SEM) classified under metrology and inspection equipment.^[1][2]

A scanning electron microscope forms images by scanning a focused electron beam across the sample surface and detecting signals generated by electron-sample interactions, principally secondary electrons and back-scattered electrons.

In variable-pressure mode, the specimen chamber is held at a moderate pressure (typically in the range of tens to hundreds of pascals) while the electron column remains under high vacuum, enabling charge dissipation on insulating surfaces through gas ionization and reducing the need for sample preparation.

In semiconductor fabrication and advanced packaging, scanning electron microscopes of this class are deployed for defect review, critical dimension measurement, and failure analysis after lithography, etch, or deposition steps.

The equipment is typically located in a cleanroom environment and is used both in-line for process monitoring and off-line in a laboratory setting for detailed root-cause investigations.

Primary applications include high-resolution imaging of semiconductor wafers, photomasks, and micro-electromechanical systems (MEMS) structures for metrology, quality assurance, and process development.

Outside semiconductor manufacturing, variable-pressure SEMs are used in materials science, life sciences, and industrial failure analysis for observing non-conductive polymers, ceramics, and biological tissues with minimal specimen alteration.
