J. Urban et al., THE SCANNING TUNNELING MICROSCOPE AS A TOOL FOR NANOLITHOGRAPHY - WRITING NANOSTRUCTURES ON SI(110) IN AIR, Microelectronic engineering, 27(1-4), 1995, pp. 113-116
In this paper, the use of the scanning tunneling microscope (STM) as a
tool for nanolithography is presented from a technological viewpoint.
STM lithography in air by field-induced oxidation of hydrogen-termina
ted Si(110) surfaces is demonstrated. Complex oxide patterns have been
produced with high reproducibility and the influence of several exper
imental parameters such as tunneling voltage, tunneling current and wr
iting speed has been studied in detail. Due to the especially strong e
tch anisotropy for the Si (110) surface, using the produced oxide patt
erns as an etch mask may enable the fabrication of nanostructures with
high lateral densities and high aspect ratios for optoelectronic, ele
ctronic or nanomechanical applications.
