In recent years, nanofabrication technology, considered as a breakthrough of human cognition and a leap of technology and an innovation of industry, has attracted wide attention from scientists. Because AFM (Atomic Force Microscope) not only can detect local spatial and electronic structure of material surface with atom scale resolution, but also has strong maneuverability to manipulate single atoms, and single molecules, and construct NEMS(Nanoelectromechanical Systems). It has greatly improved our ability of characterizing the structures of single molecules, studying the methods and mechanisms, and even constructing new nano scale information products. The recent advance on nanofabrication methods with AFM is introduced in this paper. The nanofabrication methods and mechanisms based on AFM, including tip induced modifying, nano level etching, nano chemical reaction, single atom, single molecular manipulations, and nanostructure construction, are analyzed to lay a foundation for studying and developing nano information products. Nanofabrication technology involves quite a number of subjects including physics ,chemistry ,biology, material science and machinery science. Based on the existing problems in the development of nanofabrication, the research directions that must be addressed at present are proposed as well.
