An algorithm is presented for the recognition of four types of defects present in silicon wafer images. Defect recognition is achieved by following a 3-step process: segmentation, feature extraction and classification. Multiple image segmentation algorithms are tried for locating and isolating the defects present in the silicon wafer images. The proposed image segmentation technique is based on simple concept of threshold based segmentation and edge detection based segmentation. Combination of four segmentation algorithms based on above mentioned techniques are used such that each segmentation algorithm specializes in segmenting a certain type of defect, thereby ensuring high chances of correct segmentation. Out of these segmented images, the most relevant and distinctive features are extracted and used to train an efficient neural network based classifier. For the standard sized images 2D DFT features are calculated and fed into HWO-MOLF classifier that can determine the type of defect present. Results are presented for all four types of defects.

Defect Recognition and Image Processing in Semiconductors 1997 provides a valuable overview of current techniques used to assess, monitor, and characterize defects from the atomic scale to inhomogeneities in complete silicon wafers. This volume addresses advances in defect analyzing techniques and instrumentation and their application to substrates, epilayers, and devices. The book discusses the merits and limits of characterization techniques; standardization; correlations between defects and device performance, including degradation and failure analysis; and the adaptation and application of standard characterization techniques to new materials. It also examines the impressive advances made possible by the increase in the number of nanoscale scanning techniques now available. The book investigates defects in layers and devices, and examines the problems that have arisen in characterizing gallium nitride and silicon carbide.

GENERAL DESCRIPTION OF THE SERIES Since its inception in 1966, the series of numbered volumes known as Semiconductors and Semimetals has distinguished itself through the careful selection of well-known authors, editors, and contributors. The "Willardson and Beer" Series, as it is widely known, has succeeded in publishing numerous landmark volumes and chapters. Not only did many of these volumes make an impact at the time of their publication, but they continue to be well-cited years after their original release. Recently, Professor Eicke R. Weber of the University of California at Berkeley joined as a co-editor of the series. Professor Weber, a well-known expert in the field of semiconductor materials, will further contribute to continuing the series' tradition of publishing timely, highly relevant, and long-impacting volumes. Some of the recent volumes, such as Hydrogen in Semiconductors, Imperfections in III/V Materials, Epitaxial Microstructures, High-Speed Heterostructure Devices, Oxygen in Silicon, and others promise indeed that this tradition will be maintained and even expanded. Reflecting the truly interdisciplinary nature of the field that the series covers, the volumes in Semiconductors and Semimetals have been and will continue to be of great interest to physicists, chemists, materials scientists, and device engineers in modern industry. GENERAL DESCRIPTION OF THE VOLUME This volume has contributions on Advanced Characterization Techniques with a focus on defect identification. The combination of beam techniques with electrical and optical characterization has not been discussed elsewhere.

Defects in silicon wafers affect their mechanical stability considerably during their processing and handling. In the new generation of thin silicon wafers, in addition to subsurface defects, cracks are also one of the most important defects that need to be evaluated. A comprehensive review of literature suggests the use of different techniques for non destructive evaluation (NDE) of silicon wafers. Among the few NDE techniques that can be used for both sub-surface and crack detection, Shearography has the advantage of being a whole field technique that can be utilized as a non-contact method for online inspection. Although, recently shearography has been used for sub-surface defect detection in silicon wafers, the capability of this technique to identify and detect cracks has not been investigated yet. In this work, a shearography system has been developed for nondestructive evaluation of silicon wafers. The optical set-up was arranged and several experiments were carried out to optimize its performance. Batch of perfect wafers, wafers with sub-surface defects and cracked wafers of 500?m thickness were qualitatively evaluated using the developed system. Two different loading mechanisms were used to stress the silicon wafer and the advantage of uniform thermal loading over concentrated force loading for crack and sub-surface defect detection has been discussed. In addition to crack detection, the unique potential of the developed system for detection of crack propagation has been discussed.
