전자빔 가공시스템용 진공환경의 성능평가
Characteristic Evaluation of Vacuum Chamber for EBM System
초록
It is not efficient and scarcely out of the question to use commercial expensive electron beam lithography system widely used for semiconductor fabrication process for the manufacturing application field of various devices in the small business scope. Then scanning electron microscope based electron beam machining system is maybe regarded as a powerful model can be used for it simply. To get a complete suite of thus proper system, proper chamber with high vacuum condition is necessarily required more than anything else to modify scanning electron microscope. In this study, special chamber unit using rotary pump and diffusion pump to obtain high vacuum degree was designed and manufactured and various evaluation tests fur recognize the vacuum characteristic were accomplished.
