An overview of PTB’s activities in the field of dimensional nanometrology using scanning probe microscopes (SPMs) is presented. The chapter is divided into two parts: the development of (1) high-resolution probing systems and (2) complete SPM metrology systems. The subject of SPM-probing system design comprises, among other things, the concept of the “sensor objective” to combine conventional microscopy with scanning probe techniques.
