This paper describes a fast-scanning Kerr microscope which produces quantitative and repeatable images with a scan rate of one frame/s. The rapid scan facility results in a practical system for routine examination of magnetic samples, whereas present

This paper demonstrates the desirability for efficient and extensive inspection procedures for microelectronic components. Some potential component and systems reliability implications of omitting these procedures are discussed. It is shown that many

The microstructures of five commercially available nickel-based superalloys (NIM80A, NIM90, NIM105, IN738, IN939) have been studied after heat-treatments at 4 different temperatures and for times up to 15 000 h (170 samples). In all cases for moderat

SUMMARY This paper demonstrates that the use of an IR microscope in non-destructive failure analysis of plastic encapsulated devices overcomes many of the problems previously associated with conventional failure analysis techniques. Moreover, the dev

In order to carry out effective failure analysis on semiconductor devices, it is essential to have a disciplined analytical schedule to ensure that no relevant information is lost by virtue of any haphazard approach. This paper describes the rational

The reappearance of ‘purple plague’ as a reliability and failure risk in current IC devices has led to renewed interest in the precise failure mechanisms and eventual failure mode. These are outlined and illustrated with examples of recent failur

The growth rates of dispersed thoria particles in nickel have been measured as a function of time at 1350°C in gases of two separate oxygen partialpressures. Samples were prepared for electron microscopic study after these treatments for particle si

RECENT results1 show that for the oxidation of iron–chromium alloys containing 16–38 per cent chromium, in oxygen at atmospheric pressure, the process is controlled by diffusion during the first 2 h of exposure at temperatures between 650° and 9
