STM). A cantilever with a sharp metal tip is effective in precise A distinct advantage of AFM over STM is its ability to read back the actual topography of the generated pattern, while STM is unable to give the real height [ 198].

However, due to the poor reliability of the STM tip during the nano-oxidation process, very few LON studies have been performed with this technique in the mid 1990s [ 54 ], [ 55 ], [ 108 ], [ 134 ], [ 201 Atomic force microscopy (AFM) was originally developed for atomic resolution surface topography observations. Nowadays, it is also widely used for nanolithography. AFM-based lithography is an effective method compared to conventional photolithographic processes due to its simplicity, high resolution, and low cost.

It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm. This Lithography Software Option is used for nanolithography. That is, the AFM's probe is used to alter the physical or chemical properties of the surface. Below are images of lines and indents made with an AFM probe on a PMMA surface.

Flex-Bio — AFM for biology and life science. A key success factor in life science research is the combination of multiple techniques. With the Flex-Bio, Nanosurf's Bio AFM, you can combine the AFM imaging, spectroscopy and nanomanipulation capabilities of this system with the high-end optical imaging techniques available for inverted microscopes. TABLE I. Sample preparation steps for hybrid AFM/STM lithography of SAL-601 e-beam resist. Step Equipment Temperature Time Oxide etch 50:1 HF RT 35 s Singe Convection oven 150 °C 30 min AFM vs. STM based lithographyA unique feature of AFM-based lithography is that the exposure and imaging mechanisms of the AFM operate independently. As a result, the voltage on the tip can be applied independently of the feedback which controls the tip-sample spacing.

The sample surface under the tip can be melted and evaporates. As Example of STM Lithography is presented STM image of three monolayers conducting LB film after local exposure to three electric pulses. Crater-like defects of one monolayer depth are readily seen.

The substrate is a hydrogen-passivated Si. A scanning tunneling microscope (STM) is a type of microscope used for imaging surfaces at the atomic level.

STM lithography is obtained applying tension in the range of some volts. It is possible to bank or remove matter, even in atomic quantities, according to the voltage verse. STM lithography can also remove atoms supplying tension impulses.
