3 Dip-Pen Nanolithography (DPN) . is that STM can only be used to image conductive surfaces. also known as atomic force microscopy (AFM), in 1986.

AA5000 features a full coverage of AFM/SPM features-STM, AFM, LFM Conductive AFM, MFM, EFM, Environmental Control SPM and Nano-Processing AA5000 is designed to provide images of atomic scale up to 100 micrometer. STM is also only possible with conductive samples (which many materials are not), so high-resolution AFM allows for a new avenue of characterization for interesting semiconductor and insulator nanomaterials. Gone are the days when sub-nanometer molecular resolution was the province of only STM. Since STM and AFM operate in near field regime, lithography far less affected by diffraction and proximity effect which arise with optical or e-beam lithography. Local anodisation with an AFM is a versatile method to make nanoscale quantum devices [1,2]. Here we present results based on the controlled oxidation of metallic ultra-thin films. A100 AFM- A100 PLUS AFM A100 AFM is a versatile atomic force microscope suited to a wide variety of applications including bioscience, surface science, semiconductor technology, magnetic media, polymer science, optics, chemistry and medicine.

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.

(left) Conventional e-beam lithography (EBL) at 30 kV; (right) STM lithography at 40–60 V. Low energy exposure is the key feature of STM/AFM-based lithography. After emitted at low energy (few eV), electrons lose energy due to inelastic scattering with resist molecules as well as gain energy from the high electric field.

Scanning probe lithography (SPL) describes a set of nanolithographic methods to pattern material on the nanoscale using scanning probes. It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm. The scanning tunneling microscope (STM) and atomic force microscope (AFM) provide, not only ‘eyes’ but also ‘hands’ to investigate and modify nano-objects. Therefore, not only are high resolution images available to us, but they offer a means to construct objects in the microscopic world. Atomic force microscopy (AFM) stands apart from other methods of microscopy, which use light or an electron beam to obtain an image.

Atomic force microscopy (AFM) stands apart from other methods of microscopy, which use light or an electron beam to obtain an image. AFM, also called scanning probe microscopy, scans the surface with a probe, or a flexible cantilever with a pointed tip, making very small, precise movements.

The Nanosurf AFM is ideal to e.g. check structures prepared in lithography processes.
