Interferometric coordinates measurement sytem for local probe microscopy nanometrology
 Hrabina, Jan ; Lazar, Josef ; Klepetek, P. ; Číp, Ondřej ; Čížek, Martin ; Holá, Miroslava ; Šerý, Mojmír
We present an overview of new approaches to the design of nanometrology measuring system with a focus on methodology of nanometrology interferometric techniques and associated problems. The design and development of a nanopositioning setup with interferometric multiaxis monitoring and control involved for scanning probe microscopy techniques (primarily atomic force microscopy, AFM) for detection of the sample profile is presented. Coordinate position sensing allows upgrading the imaging microscope techniques up to quantified measuring. Especially imaging techniques in the micro- and nanoworld overcoming the barrier of resolution given by the wavelength of visible light are a suitable basis for design of measuring systems with the best resolution possible. The system is being developed in cooperation with the Czech metrology institute and it is intended to operate as a national nanometrology standard combining local probe microscopy techniques and sample position control with traceability to the primary standard of length.

Interferometer controlled positioning for nanometrology
 Lazar, Josef ; Číp, Ondřej ; Čížek, Martin ; Hrabina, Jan ; Šerý, Mojmír ; Klapetek, P.
We present a system for dimensional nanometrology based on scanning probe microscopy techniques (primarily atomic force microscopy, AFM) for detection of sample profile combined with interferometer controlled positioning. The interferometric setup not only improves resolution of the position control but also ensures direct traceability to the primary etalon of length. The system was developed to operate at and in cooperation with the Czech metrology institute for calibration purposes and nanometrology. The interferometers are supplied from a frequency doubled Nd:YAG laser stabilized by linear absorption spectroscopy in molecular iodine and the interferometric configuration controls the stage position in all six degrees of freedom.
