11. Optical volumetric inspection of sub-20 nm patterned defects with wafer noise
Published: 4/2/2014
Authors: Bryan M Barnes, Francois R. Goasmat, Martin Y Sohn, Hui H. Zhou, Richard M Silver, Andras Vladar, Abraham Arceo
Abstract: We have previously introduced a new data analysis method that more thoroughly utilizes scattered optical intensity data collected during defect inspection using bright-field microscopy. This volumetric approach allows conversion of focus resolved 2-D ...

12. Documentation for Reference Material (RM) 8820: A Versatile, Multipurpose Dimensional Metrology Calibration Standard for Scanned Particle Beam, Scanned Probe and Optical Microscopy
Series: Special Publication (NIST SP)
Report Number: 1170
Published: 2/3/2014
Authors: Michael T Postek, Andras Vladar, Bin Ming, Bunday Benjamin
Abstract: Reference Material (RM) 8820 is a multipurpose instrument calibration standard available from NIST. This is a dimensional standard initially developed to replace the out of stock RM 8090 used for X and Y scale calibrations of scanned particle beam mi ...
