NanoSEM 3 D CD-SEM

The Applied Materials NanoSEM 3 D CD-SEM is a critical dimension scanning electron microscope. The Applied Materials NanoSEM 3 D CD-SEM belongs to the metrology and inspection category. The Applied Materials NanoSEM 3 D CD-SEM supports 6-inch wafers. The Applied Materials NanoSEM 3 D CD-SEM was manufactured in 2001.^[3][4][1]

A critical dimension scanning electron microscope is a metrology tool that images patterned wafer features with an electron beam to measure feature dimensions. A critical dimension scanning electron microscope is used to inspect linewidths, spaces, and related pattern geometry after lithographic pattern transfer. A critical dimension scanning electron microscope generally derives measurements from electron-signal contrast at feature edges and from calibrated image analysis routines.

A critical dimension scanning electron microscope is used in process control around patterning and pattern transfer steps. A critical dimension scanning electron microscope commonly appears after resist development, after etch, and at other checkpoints where feature size and profile control matter. A critical dimension scanning electron microscope feeds measurement results back to lithography and etch engineering for process monitoring and adjustment.

A critical dimension scanning electron microscope is applied to patterned wafers that require dimensional verification of fine features. A critical dimension scanning electron microscope is used for line and space measurements, contact or hole size checks, and review of feature fidelity across process layers. A critical dimension scanning electron microscope supports development, qualification, and routine monitoring of semiconductor patterning processes.
