Contactless VLSI Measurement and Testing Techniques

Angebote / Angebote:

This book provides readers with a comprehensive overview of the state-of-the-art in optical contactless probing approaches, in order to fill a gap in the literature on VLSI Testing.  The author highlights the inherent difficulties encountered with the mechanical probe and testability design approaches for functional and internal fault testing and shows how contactless testing might resolve many of the challenges associated with conventional mechanical wafer testing. The techniques described in this book address the increasing demands for internal access of the logic state of a node within a chip under test:Provides a single-source reference on contactless probing approaches for VLSI testing and diagnostic measurementIntroduces readers to various optical contactless testing techniques, such as Electro-Optic Probing, Charge Density Probe, and Photo-emissive ProbeDiscusses the applicability and adaptability of each technique, based on multilayer metallization, wafer level techniques, and invasivenessProvides a comparison among various contactless testing techniquesDescribes a variety of industrial applications of contactless VLSI testing
