Problems solved by technology

Therefore, there are simple axis-related corrections, wave velocity offsets, replacement of consumables, etc., which also require professional assistance, resulting in increased maintenance time and costs.
[0007] In addition, it takes time to form a high vacuum inside the shaft, so there is a problem that it takes a lot of work preparation time

Abstract

A scanning electron microscope according to the present invention enables a shaft to be detached from a sample installation unit, thereby addressing issues related to the shaft, such as simple calibration related to the shaft, misalignment of a beam speed, replacement of consumables, etc., by replacing the entire shaft. As such, the scanning electron microscope has the advantage of being simply and easily repaired and maintained.

Description

technical field [0001] The present invention relates to a scanning electron microscope, and more specifically relates to a scanning electron microscope which can be assembled and disassembled so as to be convenient, easy to maintain and manage. [0002] Moreover, the present invention also includes an image acquisition method using such a scanning electron microscope. [0003] This application claims the priority of Korean Patent Application No. 10-2019-0033312 (Title of Invention: Scanning Electron Microscope with Detachable Shaft and Image Acquisition Method Using It, Filed on March 25, 2019), Korean Patent Application All the contents contained in the application specification and drawings of No. 10-2019-0033312 are included in this specification. Background technique [0004] Generally, a scanning electron microscope scans an electron beam onto a sample and detects secondary electrons or back scattered electrons generated on the sample to obtain an image of the sample t...
