The complexity of semiconductor chips and their packages has continuously challenged the known methods to analyze them. With larger laminates and the inclusion of multiple stacked die, methods to analyze modern semiconductor products are being pushed toward their limits to support these 2.5D and 3D packages. This article focuses on these methods of fault isolation, non-destructive imaging, and destructive techniques through an iterative process for failure analysis of complex packages.

The chapter describes the equipment, defines how it is best used, and presents real-life examples. It describes a helical horizontal filament winding machine system and a vertical winding machine. The chapter provides information on in-plane (polar) winders and several types of creels, namely stationary and no twist, rotating, braking, and combinations thereof. Comprehensive descriptions of mandrel designs used in filament winding are presented in text and illustration. The chapter also reviews process control of filament winding parameters, including for some specialized winding processes and unique component types.

Education and training play an important role if the failure analyst is to be successful in his or her work. This article discusses the history of training activities in the failure/product analysis discipline and describes where this area is heading. It provides information on three areas of education and training that should be given to the analyst for him or her to be successful developing and fielding modern semiconductor components: analysis process, technology, and technique training.

Contaminants can be a cause of numerous types of system failures. There are numerous techniques for confirming contaminant presence. When the presence of a contaminant is suspected, the failure analysis team must find and eliminate the contaminant source, which can be obvious or quite subtle. This chapter summarizes a few commonly encountered contaminant sources to stimulate the reader's thinking about potential contaminant sources. A case study of titanium component washing at Litton Lasers is presented to illustrate how the presence of contaminants leads to a system failure.

Recent trends in electronic packaging, including the growing use of 3D designs and heterogeneous integration, are greatly adding to the complexity of isolating faults in semiconductor products. This chapter reviews the latest IC packaging and integration solutions and assesses the readiness level of fault isolation tools and techniques. It examines the capabilities, limitations, and optimization potential of x-ray tomography and magnetic field imaging, describes various approaches for optical fault isolation, and compares and contrasts pre-OFI sample preparation methods. The chapter also explains how time-domain and electro-optical terahertz pulse reflectometry are used to find shorts and opens in ICs and how challenges related to heterogenous integration may be met through design for testability (DFT) and built-in self-test (BIST) accommodations and the use of passive interposers.

Aluminum is the second most widely used metal in the world. It is readily available, offers a wide range of properties, and can be shaped, coated, and joined using a variety of methods. This chapter discusses some of the key attributes of wrought and cast aluminum alloys and the classifications, designations, and grades of available product forms. It also explains how aluminum alloys are used in aerospace, automotive, rail, and marine applications as well as in building and construction, electrical products, manufacturing equipment, packaging, and consumer durables such as appliances and furniture.

This chapter provides an overview of the rolling and finishing processes required to create a sheet, plate, or foil product from a direct chill (DC) cast ingot. The flow paths, equipment, and operations are described with a view to the basic evolution of the microstructure, surface characteristics, and dimensions.

Most of the counterfeit parts detected in the electronics industry are either novel or surplus parts or salvaged scrap parts. This article begins by discussing the type of parts used to create counterfeits. It discusses the three most commonly used methods used by counterfeiters to create counterfeits. These include relabeling, refurbishing, and repackaging. The article presents a systematic inspection methodology that can be applied for detecting signs of possible part modifications. The methodology consists of external visual inspection, marking permanency tests, and X-ray inspection followed by material evaluation and characterization. These processes are typically followed by evaluation of the packages to identify defects, degradations, and failure mechanisms that are caused by the processes (e.g., cleaning, solder dipping of leads, reballing) used in creating counterfeit parts.

This chapter briefly lays out the challenges associated with electrical fault isolation (EFI) brought on by continued transistor scaling and increasing package complexity. It also identifies high-priority issues and areas of technology that must be addressed for EFI tools and techniques to remain effective.

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.

This introduction presents an overview of the discovery of aluminum, the origins of the aluminum industry, and the evolution of the industry.

There are several analytical methods available that can be used in-line on whole wafers as well as off-line on de-processed products that are returned from the field. These techniques are surface analytical techniques that can be used to characterize the bulk of the material. The main six methods used in semiconductor industry are: Auger spectroscopy, dynamic secondary ion mass spectroscopy, time of flight static secondary ion mass spectroscopy (ToF-SIMS), X-ray photoelectron spectroscopy, scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDX), and transmission electron microscope-EDX. This review specifically addresses ToF-SIMS and describes some typical examples of the application of Auger and SEM-EDX.
