Title: Method and apparatus for generating surface image
Inventor: FROSIEN JUERGEN
IPC: H01J37/20
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To minimize an effect of a local charging effect and to make avoidable the negative effect of all local image distortions by setting an electrode apparatus for impressing a variable voltage to hold the potential of a surface to a constant value in an area of the surface which is to be imaged. SOLUTION: Surface charges are adjusted by a flat part of a test piece 3. The control parameter is the voltage of a charge control electrode using a reference value at a primary beam energy (fixed to a predetermined value) control device 8. The primary beam energy is selected so that a surface 3a positively charged. The bias voltage of the charge control electrode 7 is slightly negative, thereby, feeding back particles emitted at the surface 3a to a source. Surface charges by a voltage change of the control electrode 7 are adjusted through a total amount of fed back secondary particles or back scattering particles. When the surface 3a partially has a higher particle generation ratio and is apt to be more positively charged at the area, the control electrode 7 is automatically controlled to be more negative.  The particle emission at this position is accordingly reduced and charging to a more positive surface potential is prevented.
