In the last decade of the century

a brand-new field of nano scale science and technology has emerged in the world which includes nanoelectronics

nanometer scale materials

nanobilogy

nanomechanics

nanomicroscopy and nanofabrication etc.In this paper

the origination

present state and prospect of nanoelectronics have been discussed.The final goal of nano scale science and technologyis to manufacture products that possess special functions from atoms or molecules directly.This will strikingly change human models of production and living conditions.
