Editorial

This issue of Microelectronics Journal illustrates even more than usual the wide breadth of coverage. I hope this means that our readers will all find something instructive in these pages, as well. as papers immediately relevant to their special interests.

The contributions range from a detailed analysis of the problems of wafer cooling during ion implantation processes, via ceramic ray effects, high speed device packaging and liquid crystal displays to applications topics of CMOS circuit analysis and multiprocessor systems.

The multiplicity of subjects covered emphasises the wide range of disciplines which contribute to the successful design and production of a microelectronic device. It has long been apparent that the traditional barriers between the diverse subject areas are a real limitation on the speed of technological and industrial progress. Furthermore, the frightening speed of technological development in any one field militates against the necessary broadening of an engineer's horizons by peripheral reading.

It is to be hoped that by keeping our horizons wide, the Journal will remain an influence for integrating workers across the broad spectrum of microelectronic disciplines, helping us all to improve our grasp of our specialist subjects and also to keep in touch with the language, problems and achievements of others.
