Surface and Nanostructure Metrology Group

Welcome

The Surface and Nanostructure Metrology Group in the Semiconductor & Dimensional Metrology Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST), 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 US semiconductor manufacturers, metrology tool manufacturers and consortia 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 US manufacturing where surface roughness, form, and nano-structure topography are critical.

Activities include:

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