| Research Abstract |
We succeeded a fabrication of focused micro ion source array using micromachining technologies. Our micro ion source has below than 50 nm in tip radius, 50 um in emitter radius, and 150 um in emitter height. Twenty five (5x5) micro ion sources were fabricated by butch processing in the area 4 mm2. Micro ion beam of ion liquid (EMIM-BF4) was confirmed. By using Quadra pole mass spectroscopy, it is shown that our micro ion beam etches Si substrate reactively.
