Patent ID: 8207498

Claim:
An electron beam apparatus including an information processing apparatus, a display, an electron optical column that irradiates a charged-particle beam to a sample substrate which is a sample to be inspected and detects a secondary-particle signal or a two-dimensional intensity distribution based on the secondary-particle signal, a main chamber in which sample substrates are stored, a load-lock chamber used to carry each sample substrate into or out of the main chamber, and a robot which transports each sample substrate to the load-lock chamber and can automatically exchange the sample substrates: the information processing apparatus comprising: a display control unit; an electron microscope control unit which has a beam scan control block, a column control block, a stage control block, a pump control block and a robot control block; and a display data computation unit which has a recipe control block, a image processing block and a defect coordinate control block; wherein the recipe control block communicates at a high speed with the display control unit, the image processing block, the defect coordinate control block, the beam scan control block, the column control block, the stage control block, the pump control block and the robot control block based on an inspection recipe registered via the display control unit; and wherein the display has a screen for displaying and selecting a defect map, a classification map, a formed image, an observational magnification, an inspection mode which refers to an operating mode of the electron optical column in acquiring an observation image utilized for detecting a defect or a foreign matter, an observation mode which refers to an operating mode of the election optical column in acquiring a finer observation image of the defect or foreign matter, a normal mode or a charge mode which accompanies the inspection mode or the observation mode and is an irradiation condition of a primary electron beam, and displays a result of classification of a defect.
