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. 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. 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.

The Variable Temperature SPM Lab is a multi-technique system.
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. Scanning Probe Microscope AFM/STM modes in one system Featuring an innovative ergonomic design and advanced electronics, our Scientific Microscope delivers atomic-scale resolution for the cost, the price is perhaps the most surprising feature and make this microscope even more attractive. Our Educational model makes it an ideal choice for education as well as research, The NAMA-SPM offers TABLE I. Sample preparation steps for hybrid AFM/STM lithography of SAL-601 e-beam resist.
