The Radiation Tolerance Problem: Analytical Modelling of Inter-Dependency of Parameters

Radiation-induced damage presents a serious threat facing space applications. This threat has lead to an increasingly growing demand for radiation tolerant electronic devices. The radiation tolerance is likely to present an intractable problem to satisfy. One way of dealing with the radiation tolerance problem could be through analytical modelling of the many radiation-effects parameters, some of which are design dependent and others are process dependent. The paper presents analytical modelling expressions that allow for investigation of the coupling effect between a range of design and process related parameters. Examinations of the inter-dependency of these parameters would aid identifying possible solutions to the radiation tolerance problem.
