Abstract Highly-integrated radio frequency and mixed-mode devices that are manufactured in deep-submicron or more advanced CMOS processes are becoming more complex to analyze. The increased complexity presents us with many eccentric failure mechanisms that are uniquely different from traditional failure mechanisms found during failure analysis on digital logic applications. This paper presents a novel methodology to overcome the difficulties and discusses two case studies which demonstrate the application of the methodology. Through the case studies, the methodology was proven to be a successful approach. It is also proved how this methodology would work for such non-recognizable failures.

ABSTRACTElectromigration and stress - induced voiding are two of the most important metallization failure mechanisms for integrated circuits. These mechanisms are not independent since stress voiding may affect electromigration. In this paper we examine the impact of stress voiding on electromigration failure of narrow Al alloy stripes, and show that the major effects of stress voiding are significant reductions in failure times, and a non-Arrenhius temperature dependence of the lifetime. We propose a model to explain these effects based on the formation of flux divergences at pre-existing voids due to stress gradients.

Reliability assessment of components, integrated circuits, and microassemblies is clearly identified as a major factor in the on-going development of microelectronics. Since the last decade, the 3-D packaging and interconnections have emerged, and integrated packages have been developed. System-in-package (SIP) has become the principal support for integrated systems. Numerous problems are linked to their decreasing dimensions, the increasing numbers of interfaces (multichips stacked one on top of another), and plastic packages that must tolerate higher temperatures (RoHS). How is the reliability of such components assessed? What are the tools to investigate failure mechanisms in these new packages? This article gives some solutions mixing acoustic analysis, x-ray microscopy, electrical testing, and the use of specific tests points (sensors) placed in the package.

The fabrication and prolonged 500 °C electrical testing of 4H-SiC junction field effect transistor (JFET) integrated circuits (ICs) with two levels of metal interconnect is reported in another submission to this conference proceedings. While some circuits functioned more than 3000 hours at 500 °C, the majority of packaged ICs from this wafer electrically failed after less than 200 hours of operation in the same test conditions. This work examines the root physical degradation and failure mechanisms believed responsible for observed large discrepancies in 500 °C operating time. Evidence is presented for four distinct issues that significantly impacted 500 °C IC operational yield and lifetime for this wafer.

Electrostatic discharge (ESD) is a single, fast, high current transfer of electrostatic charge between two objects at different electrostatic potentials, and it is one of the most important failure mechanisms in integrated circuits due to their complex operation condition. The modes, mechanism, and models of the ESD failure were discussed. Firstly failure modes of ESD were classified and the failure mechanisms were described. Then three failure models including Wunsch and Bell model, Speakman model and Tasca model were summarized. The differences of the assumption and application area of these models were discussed in detail later. At last, suggestions for future studying ESD physics of failure model were proposed.
