The best spatial resolution that can be achieved with far-field optical fault localization techniques is around 20 times larger than the critical defect size at the 45 nm technology node. There is also a limit on the laser power that can be safely used on 45 nm devices, which further compromises fault localization precision. In this article, the authors explain how they overcome these limitations using pulsed laser-induced imaging techniques and a refractive solid immersion lens. Two case studies show how the combination of pulsed-laser scanning optical microscopy and a solid immersion lens improves localization precision and detection sensitivity.

Electronic components and assemblies are subjected to temperature variations at every stage of life, resulting in the buildup of internal stress. This article explains how such stress contributes to failures and introduces a measurement technique that allows users to visualize stress distributions and assess their effects on lifetime and reliability. Application examples illustrating the capabilities of the new topography and deformation measurement approach are also presented.

CMOS IC failure mechanisms are of three general types: bridge defects, open circuit defects, and parametric related failures. This article summarizes bridge and open-circuit defect properties and provides references for further self-study. Bridge defects are characterized based on location, their significance in terms of logic gates and transistors, and critical resistance for dc logic and timing failures. Open defects are more complex and diverse with six possible failure modes each of which are described in the article.

This article presents the results of a study conducted at Sandia National Labs to assess the effect of electrostatic discharge on surface micromachined MEMS devices. This failure mode has largely been overlooked because ESD failure mechanisms often mimic the effects of stiction-adhesion. To measure the susceptibility of MEMS devices to ESD, Sandia engineers built and tested a silicon microengine and a torsional ratcheting microactuator. Test results indicate that the effects of ESD are highly dependent on device design, component stiffness, and geometry and that slight modifications can bring improvements.

Parametric failures are of two general types. One type is due to defects that affect circuit parameters. The other type, which occurs in defect-free parts, is the result of interdie parameter statistical variation. IC failures can be caused by variations in any number of parameters including L eff , W eff , I Dsat , V t , contact resistance, effective gate oxide thickness, source and drain resistance, interconnect sheet resistance, and intrametal spacing affecting cross-talk, ground bounce noise, and IR voltage drops. These failures often influence the maximum operating frequency of the IC and are seldom detected by simple stuck-at fault, delay fault, functional, or I DDQ tests. This article discusses the origin, classification, and detection of a wide range of parametric failures.

Unit level traceability (ULT) is a powerful tool that allows complete die histories to be accessed in the course of testing and analysis. It is especially useful for identifying the likely causes of microprocessor failures and in cases where failure analysis resources are limited. In the article, the author explains how he used ULT in the investigation of a 0.25-µm CMOS processor. Using the ULT of the die, he discovered a failure signature based on die location on the wafer. One root cause of failure was traced to cross-field variation in the lithography process due to marginal focus control. Another failure, observed after burn-in, was traced to the presence of residual titanium left after metal etch.

This article discusses some of the early uses of emission microscopy in semiconductor device failure analysis and the challenges that were overcome to make it the invaluable tool it is today. One of the impediments early on was a misconception that silicon cannot emit light when, in fact, it has several light emission mechanisms that have proven useful in electron microscopy. One such mechanism, avalanche luminescence, occurs in junctions during reverse breakdown and is useful for resolving low breakdown voltage and problems with ESD protection circuits. Other light emission mechanisms discussed in the article include forward bias emission, MOS transistor saturation, and dielectric luminescence, which is used to examine oxide test structures and detect oxide defects.

This article presents a new technique for monitoring the health of lithium-ion cells. Whereas traditional methods use current, voltage, and temperature data to infer the overall health of the cell, the new method uses ultrasonic measurements to assess structural changes such as swelling, expansion, ruffling, and delamination. The article explains how and why these changes occur, how they are measured, and how they correlate with loss of battery capacity, safety, and failure. It also discusses the effect of charge and discharge cycles and the factors that contribute to gas generation.
