Abstract
This chapter describes three approaches for 3D hot-spot localization of thermally active defects by lock-in thermography (LIT). In the first section, phase-shift analysis for analyzing stacked die packages is performed. The second example employs defocusing sequences for the localization of resistive electrical shorts in 3D architectures, and the third operates in cross sectional LIT mode to investigate defects in the insulation liner of Through Silicon Vias. All three approaches allow for a precise localization of thermally active defects in all three spatial dimensions to guide subsequent high-resolution physical analyses.

Abstract
As semiconductor feature sizes have shrunk, the technology needed to encapsulate modern integrated circuits has expanded. Due to the various industry changes, package failure analyses are becoming much more challenging; a systematic approach is therefore critical. This article proposes a package failure analysis flow for analyzing open and short failures. The flow begins with a review of data on how the device failed and how it was processed. Next, non-destructive techniques are performed to document the condition of the as-received units. The techniques discussed are external optical inspection, X-ray inspection, scanning acoustic microscopy, infrared (IR) microscopy, and electrical verification. The article discusses various fault isolation techniques to tackle the wide array of failure signatures, namely IR lock-in thermography, magnetic current imaging, time domain reflectometry, and electro-optical terahertz pulse reflectometry. The final step is the step-by-step inspection and deprocessing stage that begins once the defect has been imaged.

Abstract
Thermal barrier coatings (TBCs) are applied using thermal spray coating (TSC) processes to components that are internally cooled and operated in a heated environment. The TSC microstructures are prone to interactions with common metallographic procedures that may result in artifacts and misinterpretation of the TSC microstructure. This article aims to aid in identifying metallographic TSC artifacts, specifically in the air plasma spray zirconia-based TBC, including both of its common constituents, the bond coating and the top coating. Artifacts that result from specific sectioning and mounting practices, as well as from different polishing times, are presented. Additionally, the article discusses the factors in optical microscopy and scanning electron microscopy that affect microstructure interpretation.

Abstract
Over the revolutionary era of semiconductor technology, Computer-Aided Design Navigation (CADNav) tools have played an increasingly critical role in silicon debug and failure analysis (FA) in efforts to improve manufacturing yield while reducing time-to-market for integrated circuit (IC) products. This article encompasses the key principles of CADNav for various aspects of semiconductor FA and its importance for improved yield and profitability. An overview of the required input data and formats are described for both IC and package devices, along with key considerations and best practices recommended for fast fault localization, accurate root cause analysis, FA equipment utilization, efficient cross-team collaboration, and database management. Challenges with an FA lab ecosystem are addressed by providing an integrated database and software platform that enable design layout and schematic analysis in the FA lab for quick and accurate navigation and cross-tool collaboration.

Abstract
The ultimate goal of the failure analysis process is to find physical evidence that can identify the root cause of the failure. Transmission electron microscopy (TEM) has emerged as a powerful tool to characterize subtle defects. This article discusses the sample preparation procedures based on focused ion beam milling used for TEM sample preparation. It describes the principles behind commonly used imaging modes in semiconductor failure analysis and how these operation modes can be utilized to selectively maximize signal from specific beam-specimen interactions to generate useful information about the defect. Various elemental analysis techniques, namely energy dispersive spectroscopy, electron energy loss spectroscopy, and energy-filtered TEM, are described using examples encountered in failure analysis. The origin of different image contrast mechanisms, their interpretation, and analytical techniques for composition analysis are discussed. The article also provides information on the use of off-axis electron holography technique in failure analysis.
