Total ionizing dose effects on MOS and bipolar devices in the natural space radiation environment
Mechanisms that control the response of MOS and bipolar devices to ionizing radiation in the natural space environment are briefly reviewed. Standard tests based on room-temperature irradiation and elevated temperature annealing are described for MOS devices to bound the effects of oxide and interface-trap charge in space. For bipolar devices that exhibit enhanced low-dose-rate sensitivity, a standard test equivalent to that developed for MOS devices is not available. However, screening techniques based on room temperature and/or elevated temperature irradiations are described which can minimize the risk to spacecraft and satellite electronics from this phenomenon.
