마이크로 플라즈마 전극가공을 위한 FIB 연구

The application of focused ion beam (FIB) technology in micro/nano machining has become increasingly popular. Its use in micro/nano machining has advantages over contemporary photolithography or other micro/nano machining technologies such as small feature resolution, the ability to process without masks and being accommodating for a variety of materials and geometries. This paper was carried out some experiments of the micro plasma electrode fabrications using FIB. The sputtering of FIB has one major problem that is redeposited by sputtered material including $Ga^+$ ion source. Therefore we have verified the effect of the reposition by EDX. And the optimal condition is suggested to machine the micro plasma electrode.
