Surface and Interface Metrology Group

Establishes best-in-the-world SI-traceable length metrology for 3D nanostructures using high-throughput, non-destructive measurement methods. Provides measurement solutions for defect and dimensional metrology needs.

The Surface and Interface Metrology Group works 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.
