What it is
The Zeiss Leo 1550 is a scanning electron microscope. The Zeiss Leo 1550 is categorized as metrology and inspection equipment.[1][2]
How it works
ProSEM is a software package for SEM image analysis and measurements. ProSEM allows automated feature size critical dimension measurements from saved SEM images. ProSEM uses automated edge detection for repeatable and consistent measurements. ProSEM can also batch process images.[4]
Where it fits in the process flow
General reference — not yet source-verifiedScanning electron microscopes sit in characterization and inspection flows rather than in material deposition, etch, or lithographic patterning itself. Scanning electron microscopes are typically used after process steps when engineers need visual confirmation of pattern shape, surface condition, defect signatures, or cross section quality. Scanning electron microscopes also support failure analysis, process development, and root cause investigation alongside production metrology.
Applications
ProSEM allows automated feature size critical dimension measurements from saved SEM images. ProSEM is intended for SEM image analysis and measurements. ProSEM can improve measurement repeatability and consistency compared with hand-drawn measurement bars on an image.[4]
