141. Image Sharpness Measurement in Scanning Electron Microscope - Part III
Published: 7/1/1999
Authors: Samuel N Jones, Robert D. Larrabee, Michael T Postek, Andras Vladar, Nien F Zhang
Abstract: Fully automated or semi-automated scanning electron microscopes (SEM) are now commonly used in semiconductor production and other forms of manufacturing. Testing and proving that the instrument is performing at a satisfactory level of sharpness is an ...

142. Toward a Unified Advanced CD-SEM Specification for Sub 0.18 Micrometer Technology
Published: 6/1/1998
Authors: J Allgair, C Archie, W Banke, H Bogardus, J Griffith, H Marchman, Michael T Postek, L Saraf, J Schlesinger, B Singh, N. Sullivan, L Trimble, Andras Vladar, A Yanof
Abstract: The stringent critical dimension (CD) control requirements in cutting edge device facilities have placed significant demands on metrologists and upon the tools they use. We are developing a unified, advanced critical dimension scanning electron micro ...

144. Final Report, 1997-1998 NIST/SEMATECH Collaboration for Improvement of High-Accuracy Critical-dimension Metrology for Semiconductor Manufacturing
Published: 3/30/1998
Authors: Andras Vladar, Michael T Postek
Abstract: Beginning on or about April 1, 1997, the National Institute of Standards and Technology (NIST) received partial support from SEMATECH to collaborate in a program designated 1997-1998 NIST/SEMATECH Collaboration for Improvement of High-Accuracy Critic ...

145. Image Sharpness Measurement in Scanning Electron Microscopy - Part I
Published: 1/1/1998
Authors: Michael T Postek, Andras Vladar
Abstract: This study introduces the idea of the sharpness concept in relationship to the determination of scanning electron microscope (SEM) perfomance. Scanning electron microscopes are routinely used in many manufacturing environments. Fully automated or sem ...

146. Fourier Transform Feedback for Scanning Electron Microscopes Used in Semiconductor Metrology
Published: 7/1/1997
Authors: Michael T Postek, Andras Vladar, M P Davidson
Abstract: The utility of the sharpness concept for use on metrology scanning electron microscopes (SEM) as implemented through the Fourier transform technique has been clearly demonstrated and documented. The original methods for sharpness analysis were labor- ...

147. Inexpensive Digital Imaging?
Published: 6/1/1997
Authors: Michael T Postek, Andras Vladar
Abstract: The capture of digital images through the use of a frame grabber provides tremendous advantages to scanning electron microscopy. Accessory frame grabbers can range in price from very inexpensive to several thousand dollars. This work investigates the ...

148. Performance Analysis Tool for Scanning Electron Microscopes Used in Semiconductor Metrology
Published: 4/1/1997
Authors: Michael T Postek, Andras Vladar, M P Davidson
Abstract: Scanning electron microscopes (SEM) are being utilized extensively in the production environment, and these instruments are approaching full automation. Once a human operator is no longer monitoring the instrument''s performance and multiple instrume ...

149. High-Accuracy Critical-Dimension Metrology Using a Scanning Electron Microscope
Published: 12/31/1996
Authors: J R. Lowney, Andras Vladar, Michael T Postek
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=24182

150. Is Your Scanning Electron Microscope Hi-Fi?
Published: 12/7/1996
Authors: Andras Vladar, Michael T Postek, S Davilla
Abstract: The scanning electron microscope (SEM) historically has been used mainly as an image-producing device and, in spite of certain obvious and sometimes serious electronics problems, serves in this function as an acceptable and effective instrument for m ...
