Surface and Nanostructure Metrology Group


The Surface and Nanostructure Metrology Group establishes best-in-the-world SI-traceable length metrology for 3D nanostructures using high-throughput, non-destructive measurement methods with rigorous nanoscale reference metrology. We work closely with leading U.S. semiconductor manufacturers, nanoelectronics, and metrology tool manufacturers to provide new measurement solutions for critical defect and dimensional metrology needs. We develop the fundamental measurement science and data analysis methods in support of government and U.S. manufacturing where surface roughness, form, and nano-structure topography are critical.

Activities include:

  • modeling for deep sub-wavelength optical metrology and scanned probe dynamics
  • developing advanced optical measurement methods and algorithms to establish the forensic science underpinnings for ballistics and forensic topography
  • realizing new atomic scale metrology methods to support the advanced needs of nano-electronic and nano-manufacturing industries.
