abstract = {A new method has been established for the reproducible
fabrication of high quality, metallic nanogaps on silicon
chips suitable for liquid based nanometer scale devices.
Realization of mu m structures connected to nanogaps with
gap sizes down to 30 nm has been achieved by a combination
of an optical and an electron-beam (e-beam) lithography step
using an optimised adhesion layer/metallic layer combination
(Ti/Pt/Au-three layer combination) and an adopted two layer
e-beam resist. The quality of the interconnects between
optically and e-beam lithographically defined structures and
the surface roughness of the gold nanogaps have been
improved by a controlled temperature treatment. With this
method the production of a variety of different gap shapes
could be demonstrated. Specifically the lithographic
structures have been successfully covered by a protection
layer, except of a 200 nm x 400 nm size access window
located on top of the nanogaps, making it suitable for
applications in liquid environment such as molecular and/or
electrochemical metal deposition. (C) 2005 Elsevier Ltd. All
