SURFACE AND BULK EFFECTS DUE TO SPACE RADIATIONS IN ELECTRONIC COMPONENTS

摘要

Radiation is damaging to all types of component, but in most cases the critical level is higher than that actually experienced in space. Components using organic materials and semiconductors are the most vulnerable to damage by radiation. Semiconductor devices are prone to degradation of the parameters necessary for successful operation, both in the bulk of the material and at the surface of the device, the latter being due to effects within and on the protective oxide layer. The complete shielding effect of the body of the spacecraft is difficult to compute;and in all cases the decision to fly a component should be based on its known sensitivity to radiation and the radiation environment of the orbit into which it is placed.
