Electron beam apparatus, and inspection instrument and inspection process thereof

A beam source of an inspection apparatus discharges a beam, and a stage system holds a specimen and moves in at least one direction. A primary optical system directs the beam to the specimen, and a secondary optical system guides a secondary beam coming from the specimen. A sensor outputs an electri...

Beschreibung
Zusammenfassung:	A beam source of an inspection apparatus discharges a beam, and a stage system holds a specimen and moves in at least one direction. A primary optical system directs the beam to the specimen, and a secondary optical system guides a secondary beam coming from the specimen. A sensor outputs an electric signal of the specimen image from the secondary beam, an image processor generates image information of the specimen by processing the electric signal output by the sensor, and a host computer generates an inspection timing signal for controlling the sensor to transfer the image information at a preset data transfer rate.
