Standard Guide for Neutron Irradiation of Unbiased Electronic Components
1.1 This guide strictly applies only to the exposure of unbiased silicon (Si) or gallium arsenide (GaAs) semiconductor components (integrated circuits, transistors, and diodes) to neutron radiation from a nuclear reactor source to determine the permanent damage in the components. Validated 1-MeV displacement damage functions codified in National Standards are not currently available for other semiconductor materials.
1.2 Elements of this guide, with the deviations noted, may also be applicable to the exposure of semiconductors comprised of other materials except that validated 1-MeV displacement damage functions codified in National standards are not currently available.
1.3 Only the conditions of exposure are addressed in this guide. The effects of radiation on the test sample should be determined using appropriate electrical test methods.
1.4 This guide addresses those issues and concerns pertaining to irradiations with reactor spectrum neutrons.
1.5 System and subsystem exposures and test methods are not included in this guide.
1.6 This guide is applicable to irradiations conducted with the reactor operating in either the pulsed or steady-state mode. The range of interest for neutron fluence in displacement damage semiconductor testing range from approximately 109 to 1016 1-MeV n/cm2.
1.7 This guide does not address neutron-induced single or multiple neutron event effects or transient annealing.
1.8 This guide provides an alternative to Test Method 1017.3, Neutron Displacement Testing, a component of MIL-STD-883 and MIL-STD-750. The Department of Defense has restricted use of these MIL-STDs to programs existing in 1995 and earlier.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
