The scanning tunneling microscope (STM) is a superb laboratory instrument for atomic and molecular imaging of surfaces. The STM has also proved to be a powerful tool in the manufacture of nanometer size patterns and structures on solid surfaces. Likewise, the STM permits to conceive a future technology of nanoscale systems and devices capable of reaching the limit of integration involving sigle atom manipulations. This paper illustrates the novel possibilities of STM and shows results and figure that corroborate the potencial use of this microscope in the XXI century electronics industry. In particular, we report experimental results of nanostructures formation, of 100 A order on gold surfaces and gold-graphite bilayers, with a Burleigh Instruments microscope operating in air.
