FIB 가공 공정 특성 분석

The analysis of sputtering characteristics using Focused Ion Beam according to Focal Length

The application of focused ion beam (FIB) technology in micro/nano machining has become increasingly popular. Its usage 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 focus to apply the sputtering technology accumulated by experiments to 3d structure fabrication with high resolution. Therefore some verifications and discussions of the characteristics of FIB sputtering results according to focal length were described in this paper. And we suggested the definition of rectangular pattern profile and made the verifications of sputtering results based on definition of it.
