Scanning probe microscopy (SPM) covers several related technologies for imaging and SPM measuring surfaces on a fine scale, down to the level of molecules and groups of atoms. SPM machine also can be utilized for lithographic technique, known as Scanning Probe Lithography (SPL), in which a microscopic or nanoscopic stylus is moved mechanically across a surface to form a pattern. SPL is capable of patterning sub-30nm features with nanometer-scale alignment registration. It is a relatively simple, inexpensive, reliable method for patterning nanometer-scale features on various substrates. It has potential applications for nanometer-scale research, for maskless semiconductor lithography, and for photomask patterning. Contact Dr Sabar D. Hutagalung. Email: email@example.com.
