ABSTRACT:
A target material having pores is disposed on a substrate. A high energy beam is irradiated to the inner walls of the pores of the target material in a slanting direction. Constituent atoms or molecules of the target material are detached from it to obtain a single or plurality of ultrafine particles separated as a unit substance. The superfine particles are formed at desired positions corresponding to the pores of the target material. Besides, by using an amorphous carbon substrate as the substrate, fullerenes such as an onion-like graphite are formed with the ultrafine particles as nucleation points. When the high energy beam is irradiated to at least two neighboring metal ultrafine particles, these metal ultrafine particles are bonded mutually. When the obtained metal ultrafine particle bonded body has a corresponding grain boundary, the high energy beam is further irradiated to lower value .SIGMA. of the corresponding grain boundary of the bonded interface. Besides, the metal ultrafine particle bonded body can also be made into a monocrystal grain or a polycrystal grain. Such a metal ultrafine particle bonded body is stable.
