S 8800 CD-SEM
What it is
The Hitachi S 8800 is a critical dimension scanning electron microscope. The Hitachi S 8800 is a metrology and inspection tool made by Hitachi.[2][3]
How it works
General reference — not yet source-verifiedA critical dimension scanning electron microscope forms images by scanning a focused electron beam across a sample and detecting emitted signals from the surface region. A critical dimension scanning electron microscope derives dimensional measurements from those images through edge detection, recipe control, and repeatable stage positioning.
Where it fits in the process flow
General reference — not yet source-verifiedA CD-SEM sits in the metrology loop around lithography and pattern transfer. A CD-SEM is commonly used after resist development and after etch to verify that printed or transferred dimensions remain within process targets and to provide feedback for exposure, focus, dose, etch bias, and process stability.
Applications
General reference — not yet source-verifiedA CD-SEM is used for measurement of patterned semiconductor features such as lines, spaces, contact openings, and other critical structures formed during device fabrication. A CD-SEM also supports process characterization, inline monitoring, defect review in a dimensional context, and correlation of pattern results across lithography and etch steps.
