Abstract:
Metrology tools are provided, which comprise both active and passive vibration isolation devices, passive or active isolation systems such as constrained layer dampers, particle impact dampers or liquid impact dampers, and/or noise cancellation transducers, combined in different supporting structures of the metrology tool to dampen and reduce vibrations at a wide range of frequencies and intensities, and to which frequency range spectral analysis and optimization may be applied to determine specific tool configurations according to the provided principles.
