AFM Applications CHAPTER 7 126 Because the AFM is capable of measuring nanometer scale images of insulating surfaces with little or no sample preparation, it has a vast number of applications in many areas of science and technology. Tis chapter serves as an introduction, or a snapshot, to AFM applications. Te applications are presented in a “picture” format. Besides the applications listed in this chapter, Chapter 4 on Imaging Modes also presents several applications for atomic force microscopes. Te primary uses for the AFM are: Visualization: Te AFM measures three dimensional images of surfaces and is very helpful for visualizing surface topography. Spatial Metrology : Nanometer sized dimensions of surface features are measurable with the AFM. Physical Property Maps: With many of the modes (see Chapter 4) it is possible to measure surface physical property maps. Tese techniques are, for the most part, qualitative. After the initial invention of the AFM in 1986 there was a great e±ort focused on developing AFM instrumentation. Within a few short years, the instruments moved from being esoteric devices requiring a Ph.D. to operate to table top instruments that could be operated by technicians. From 1990 to 2000 applications for the AFM moved from fundamental physics to most areas of science and technology. It is estimated that in 2006 there are approximately 10,000 AFM’s in use around the world.

Chapter 7 • AFM Applications As with most scientif c instruments, the initial applications For the A±M were in basic and applied research; that is, the A±M was used to push Forward the Frontiers oF knowledge. T e primary objective oF this type oF research is to publish a paper in a scientif c or technical journal. AFter its initial use For basic research, the A±M began to be used For product and process development. T e goal oF this type oF application is to create a better product. Many oF these applications are in the high and advanced technology industries such as the disk drive and semiconductor industries. It is expected that as nanotechnology processes become important For producing products, the A±M will f nd many applications in quality and process control. Again, the initial process control applications For the A±M are in the semiconductor and data storage industries. Beginning in approximately 2000, the emergence oF nanotechnology Funding throughout the world led to new applications For atomic Force microscopes. In many cases, nanotechnology is directly related to the traditional f elds in science and engineering. ±igure 7-1 shows the relationship between traditional science and technology and nanotechnology. FIGURE 7-1 Several traditional scientif c and engineering disciplines contribute to the f eld oF nanotechnology. Nanotechnology
