'Scanning tunneling Microscopy and Atomic Force Microscopy:  Application to
Biology and Technology', by P. K. Hansma, V. B. Elings, O. Marti, and C. E.
Bracker.  Science, Vol. 242 No. 4876 October 1988 page 209.

Most interesting quote:  'In a remarkable paper written more than 25 years
ago, Feynman pointed out that if we can arrange atoms and molecules the way
we want "we will get an enormously greater range of properties that
substances can have, and of different things that we can do" (25).  The STM
has brought this dream much closer to reality.  For example, Becker,
Golovchenko, and Swartzentruber (26) have placed what appears to be a
single atom onto a germanium surface.  More recently, Foster, Frommer, and
Arnett (27) have pinned an organic molecule in a particular location on a
graphite surface.  Even before atomic and molecular engineering applications
become practical, the STM may be used for micrometer-scale jobs like the
repair of (very expensive) masks for integrated circuit production (28).'
