141. Digital Imaging for Scanning Electron Microscopy
Published: 1/1/1996
Authors: Michael T Postek, Andras Vladar
Abstract: The development and application of digital imaging technology has been one of the major advancements in scanning electron microscopy (SEM) during the past several years. This digital revolution has been brought about by significant progress in semico ...

142. SEM Image Sharpness Analysis
Published: 1/1/1996
Authors: Michael T Postek, Andras Vladar
Abstract: The technique described here, utilizing the sharpness concept, is facilitated by the use of the FFT techniques to analyze the electron micrograph to obtain the evaluation. This is not the first application of Fourier techniques to SEM images, but it ...

143. Workshop Report 3: Edge Positions From Scanning Electron Microscope Signals by Comparing Models With Measure
Published: 8/6/1995
Authors: J R. Lowney, Michael T Postek, Andras Vladar
Abstract: There is a pressing need in the semiconductor industry to determine the dimensions of lithographically produced features on wafers and masks down to the l0?nm level of accuracy. Such measurements involve the accurate location of line edges, the subtr ...

144. Workshop Report 1: Scanning Electron Microscope Metrology as Related to a Defined Edge Structure
Published: 1/1/1995
Authors: Michael T Postek, Andras Vladar, G Banke, T Reilly
Abstract: An accurate electron beam model is primary to the understanding of the SEM image. Several independently developed Monte Carlo models have been introduced for this purpose and a modeling round-robin has just been conducted to compare the results of th ...

147. A Monte Carlo Model for SEM Linewidth Metrology
Published: 5/1/1994
Authors: J R. Lowney, Michael T Postek, Andras Vladar
Abstract: A scanning electron microscope (SEM) can be used to measure the dimensions of the microlithographic features of integrated circuits. However, without a good model of the electron-beam / specimen interaction, accurate edge location cannot be obtained. ...

148. Electron Beam Interaction Modeling as Applied to X-Ray Lithography Mask SEM Linewidth Metrology
Published: 1/1/1994
Authors: Michael T Postek, J R. Lowney, Andras Vladar, William J. Keery, Egon Marx, Robert D. Larrabee
Abstract: This work provides an approach to improved x?ray mask linewidth metrology and a more precise edge location algorithm for measurement of feature sizes on x?ray masks in commercial instrumentation. The transmitted electron detection mode is also useful ...
