61. Zero-Order Imaging of Device-Sized Overlay Targets Using Scatterfield Microscopy
Published: 3/1/2007
Authors: Bryan M Barnes, Lowell P. Howard, P Lipscomb, Richard M Silver
Abstract: Patterns of lines and trenches with nominal linewidths of 50 nm have been proposed for use as an overlay target appropriate for placement inside the patterned wafer die.  The NIST Scatterfield Targets feature groupings of eight lines and/or tren ...

62. A Time-Resolved Kinetic Monte-Carlo Simulation Study On Si (111) Etching
Published: 1/1/2007
Authors: Hui Zhou, Joseph Fu, Richard M Silver
Abstract: In this paper we have extended the Kinetic Monte-Carlo simulation method to study the etching dynamics of Si (111) surfaces in NH4F in a time-resolved basis. We have examined the step-flow dynamics of Si(111) etching using various simulation window s ...

63. Calibrated Overlay Wafer Standard
Series: Special Publication (NIST SP)
Report Number: 260-165
Published: 1/1/2007
Authors: Michael T. Stocker, Richard M Silver, Ravikiran Attota, Jay Shi Jun
Abstract: This document describes the physical characteristics of Standard Reference Material SRM 5000, provides guidance for its use in calibrating overlay (OL) tools, and gives information and precautions concerning its care and handling.Standard Reference M ...

64. Fundamental Limits of Optical Critical Dimension Metrology: A Simulation Study
Published: 1/1/2007
Authors: Richard M Silver, Thomas Avery Germer, Ravikiran Attota, Bryan M Barnes, B Bunday, J Allgair, Egon Marx, Jay Shi Jun
Abstract: This paper is a comprehensive summary and analysis of a SEMATECH funded project to study the limits of optical critical dimension scatterometry.  The project was focused on two primary elements: 1) the comparison, stability, and validity of indu ...

65. Advanced Metrology Needs for Nanoelectronics Lithography
Published: 10/1/2006
Authors: Stephen Knight, Ronald Dixon, Ronald Leland Jones, Eric Lin, Ndubuisi G Orji, Richard M Silver, Andras Vladar, Wen-li Wu
Abstract: The semiconductor industry has exploited productivity improvements through aggressive feature size reduction for over four decades. While enormous effort has been expended in developing the optical lithography tools to print ever finer features, sign ...

66. Illumination Optimization for Optical Semiconductor Metrology
Published: 9/1/2006
Authors: Bryan M Barnes, L Howard, Richard M Silver
Abstract: Uniform sample illumination via K hler illumination, is achieved by establishing a pair of conjugate focal planes; a light source is focused onto the condenser lens aperture while the image of the field aperture is focused at the plane of the specime ...

67. National Nanotechnology Initiative Interagency Workshop on Instrumentation and Metrology for Nanotechnology Grand Challenge Report
Published: 8/1/2006
Authors: Michael T Postek, Richard R Cavanagh, C M Allocca, Douglas T Smith, Robert D Shull, David A Wollman, David G Seiler, Stephen Knight, A Diebold, Richard M Silver, Charles W Clark, Kevin W Lyons, James R Whetstone, Ronald F Boisvert

68. Damping mechanisms for precision applications in UHV environment
Published: 5/1/2006
Authors: Sumanth B. Chikkamaranahalli, R. R Vallance, Bradley N Damazo, Richard M Silver
Abstract: Surface analysis techniques such as scanning probe microscopy (SPM) have undergone significant advances and are attractive for application to electron and optical devices such as micro lenses, vacuum tubes, electron tubes, etc. For surface stability ...

69. Optical Critical Dimension Measurement and Illumination Analysis using the Through-focus Focus Metric
Published: 3/24/2006
Authors: Ravikiran Attota, Richard M Silver, M R Bishop, Ronald G Dixson
Abstract: In this paper we present utility of the out of focus optical microscope images for metrology applications as opposed to the best focus images. Depending on the type of analysis, considerable beneficial information can be deduced from the out of focus ...

70. Koehler Illumination for High-Resolution Optical Metrology
Published: 3/1/2006
Authors: Martin Y Sohn, Bryan M Barnes, Lowell P. Howard, Richard M Silver, Ravikiran Attota, Michael T. Stocker
Abstract: Accurate preparation of illumination is critical for high-resolution optical metrology applications such as line width and overlay measurements. To improve the detailed evaluation and alignment of the illumination optics, we have separated Koehler il ...
