21. Nano- and Atomic-Scale Length Metrology
Published: 1/1/2006
Authors: Theodore Vincent Vorburger, Ronald G Dixson, Joseph Fu, Ndubuisi George Orji, Shaw C Feng, Michael W Cresswell, Richard A Allen, William F Guthrie, Wei Chu
Abstract: We discuss nano-scale length metrology of linewidth, step height, and line edge roughness (LER). These properties are of growing importance to the function and specification of semiconductor devices as the dimensions of semiconductor devices shrink t ...

22. Discrepancies Between Roughness Measurements Obtained With Phase Shifting and White-Light Interferometry
Published: 10/1/2005
Authors: Hyug-Gyo Rhee, Theodore Vincent Vorburger, Jonathan W. Lee, Joseph Fu
Abstract: Discrepancies between phase shifting interferometry and white-light interferometry have been observed in step height and surface roughness measurements. The discrepancies have a strong relation to the roughness average parameter of the surface. The s ...

23. The Study of Silicon Stepped Surfaces as Atomic Force Microscope Calib Standards With a Calibrated AFM at NIST
Published: 9/29/2005
Authors: V W. Tsai, Theodore Vincent Vorburger, Ronald G Dixson, Joseph Fu, R Koning, Richard M Silver, Edwin Ross Williams
Abstract: Due to the limitations of modern manufacturing technology, there is no commercial height artifact at the sub-nanometer scale currently available. The single-atom steps on a cleaned silicon (111) surface with a height of 0.314 nm, derived from the lat ...

24. Line Edge Roughness Metrology Using Atomic Force Microscopes
Published: 1/1/2005
Authors: Ndubuisi George Orji, Theodore Vincent Vorburger, Joseph Fu, Ronald G Dixson, C V Nguyen, Jayaraman Raja
Abstract: Line edge roughness measurements using two types of atomic force microscopes and two types of tips are compared. Measurements were made on specially prepared samples with inscribed edge roughness of different amplitudes and wavelengths. The spatial w ...

25. Linewidth Measurement from a Stitched AFM Image
Published: 1/1/2005
Authors: Joseph Fu, Ronald G Dixson, Ndubuisi George Orji, Theodore Vincent Vorburger, C V Nguyen
Abstract: Image stitching is a technique that combines two or more images to form one composite image, which provides a field of view that the originals cannot.  It has been widely used in photography, medical imaging, and computer vision and graphics. &n ...

26. The Influence of Defects on the Morphology of Si (111) Etched in NHF
Published: 1/1/2005
Authors: Hui Zhou, Joseph Fu, Richard M Silver
Abstract: We have implemented a kinetic Monte-Carlo (KMC) simulation to study the morphologies of Si (111) surfaces etched in NHF. Although our initial simulations reproduced the previous results from Hines, it failed to produce the morphologies observed in ou ...

27. Traceable Pico-Meter Level Step Height Metrology
Published: 12/1/2004
Authors: Ndubuisi George Orji, Ronald G Dixson, Joseph Fu, Theodore Vincent Vorburger
Abstract: The atomic force microscope (AFM) increasingly being used as a metrology tool in the semiconductor industry where the features measured are at the nanometer level and continue to decrease. Usually the height sensors of the AFM are calibrated using st ...

28. An Image Stitching Method to Eliminate the Distortion of the Sidewall in Linewidth Measurement
Published: 5/1/2004
Authors: Xuezeng Zhao, Joseph Fu, Wei Chu, C V Nguyen, Theodore Vincent Vorburger
Abstract: Nano-scale linewidth measurements are performed in semiconductor manufacturing, the data storage industry, and micro-mechanical engineering. It is well known that the interaction of probe and sample affects the measurement accuracy of linewidth measu ...

29. Study on an Image Stitching Method for Linewidth Measurement
Published: 4/1/2004
Authors: Wei Chu, Xuezeng Zhao, Joseph Fu, Theodore Vincent Vorburger
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=822240

30. Nano-Lithography in Ultra-High Vacuum (UHV) for Real World Applications
Published: 3/11/2004
Authors: James D Gilsinn, Hui Zhou, Bradley N Damazo, Joseph Fu, Richard M Silver
Abstract: As nano-lithography technology improves, more companies and research groups have the capability to create nano-scale structures. Scanning tunneling microscopes (STMs) are commonly used to create these structures and evaluate them afterward. One diffi ...
