The Zeiss 1540 EsB is a field emission scanning electron microscope (FE-SEM).[1]
What it is
The Zeiss 1540 EsB is a field emission scanning electron microscope.[1]
How it works
General reference — not yet source-verifiedA field emission scanning electron microscope uses a field emission gun to produce a finely focused electron beam. The beam is scanned across the sample surface in a raster pattern. Interaction of the beam with the sample generates various signals, including secondary electrons, backscattered electrons, and characteristic X-rays, which are collected by detectors to form an image.
Where it fits in the process flow
General reference — not yet source-verifiedIn semiconductor manufacturing, critical-dimension scanning electron microscopes are used after pattern etching to measure feature sizes and inspect for defects. The tool is typically placed in a metrology and inspection area of the fab, receiving wafers from etching or deposition steps and feeding measurement data to process control systems.
