摘要
A surface potential distribution measurement method and device including setting a sample having a surface with a surface potential distribution in a sample installation unit wherein both an electric field intensity formed on the sample surface and a potential bias component of the sample are variable, and scanning the sample surface in a one-dimensional or two-dimensional manner by irradiating a charged particle beam to the sample. The method also includes obtaining a detection signal from charged particles generated by the scanning, to measure the surface potential distribution of the sample by varying the electric field intensity and the potential bias component in order to control a quantity of the detection signal obtained from the charged particles.
