Technology and progress of nano machining using focused ion beam

The continuously developing nanotechnology gives an increasing prominence to nanometer manufacturing of core functional device, which functions as a bridge between the relevant design and ap- plication research. The focused ion beam machining represents an important technology for nanoscale manufacturing. This paper starts with an overview of the, and of the development of method and key tech- nology of FIB nano machining and the discussion of sputtering yield, redeposition and FIB nano direct writing method and so on, proceeds to the typical applications of FIB nano machining technology in the areas of basic research and manufacturing nanometer functional device, and ends with the development prospect in the different view of the gear and mechanism.
