21. Controlling Formation of Atomic Step Morphology on Micro-patterned Si (100)
Published: 8/9/2011
Authors: Kai Li, Pradeep Narayanan Namboodiri, Sumanth B. Chikkamaranahalli, Gheorghe Stan, Ravikiran Attota, Joseph Fu, Richard M Silver
Abstract: Micro scale features are fabricated on Si (100) surfaces using lithographic techniques and then thermally processed in an ultra high vacuum (UHV) environment. Samples are flash heated at 1200 °C and further annealed at 1050 °C for 18 hours. The surf ...

22. Dimensional Analysis of Through Silicon Vias Using the TSOM Method
Published: 7/12/2011
Authors: Ravikiran Attota, Andrew Rudack
Abstract: There is a great need for accurate, truly-3D metrology solutions that can be used for analysis of high aspect ratio features such as through-silicon-vias (TSVs). Through-focus scanning optical microscopy (TSOM) is an optical metrology method that pr ...

23. TSOM Method for Semiconductor Metrology
Published: 4/18/2011
Authors: Ravikiran Attota, Ronald G Dixson, John A Kramar, James Edward Potzick, Andras Vladar, Benjamin D. Bunday, Erik Novak, Andrew C. Rudack
Abstract: Through-focus scanning optical microscopy (TSOM) is a new metrology method that achieves 3D nanoscale measurement resolution using conventional optical microscopes; measurement sensitivities are comparable to what is typical using Scatterometry, SEM ...

24. Characterizing a Scatterfield Optical Platform for Semiconductor Metrology
Published: 12/21/2010
Authors: Bryan M Barnes, Ravikiran Attota, Richard Quintanilha, Martin Y Sohn, Richard M Silver
Abstract: Scatterfield microscopy is the union of a high-magnification imaging platform and the angular and/or wavelength control of scatterometry at the sample surface. Scatterfield microscopy uses Köhler illumination, where each point on the source translat ...

25. Nanoparticle size and shape evaluation using the TSOM optical microscopy method
Published: 6/6/2010
Authors: Ravikiran Attota, Richard J Kasica, Lei Chen, Premsagar Purushotham Kavuri, Richard M Silver, Andras Vladar
Abstract: We present a novel optical TSOM (through-focus scanning optical microscopy - pronounced as 'tee-som') method that produces nanoscale dimensional measurement sensitivity using a conventional optical microscope. The TSOM method uses optical information ...

26. Nanoscale Measurements With the TSOM Optical Method
Series: OTHER
Published: 1/4/2010
Author: Ravikiran Attota
Abstract: A novel through-focus scanning optical microscope (TSOM - pronounced as 'tee-som') technique that produces nanometer dimensional measurement sensitivity using a conventional optical microscope by analyzing images obtained at different focus positions ...

27. Optical TSOM method for 3D interconnect metrology
Published: 11/18/2009
Author: Ravikiran Attota
Abstract: There is a great need for high accurate, truly-3D metrology solutions that can be used for analysis of high aspect ratio features such as through-silicon-vias (TSVs). In this presentation we propose evaluating the viability of the newly developed th ...

29. Through-focus Scanning and Scatterfield Optical Methods for Advanced Overlay Target Analysis
Published: 9/1/2008
Authors: Ravikiran Attota, Michael T. Stocker, Richard M Silver, Nathanael A Heckert, Hui Zhou, Richard J Kasica, Lei Chen, Ronald G Dixson, Ndubuisi George Orji, Bryan M Barnes, Peter Lipscomb
Abstract: In this paper we present overlay measurement techniques that use small overlay targets for advanced semiconductor applications. We employ two different optical methods to measure overlay using modified conventional optical microscope platforms. They ...

30. Through-focus scanning optical microscope imaging method for nano-scale dimensional analysis
Published: 9/1/2008
Authors: Ravikiran Attota, Richard M Silver
Abstract: We present a novel optical technique that produces nanometer dimensional measurement sensitivity using a conventional bright-field optical microscope, by analyzing two-dimensional through-focus scanning optical microscope (TSOM) images constructed us ...
