宇航用双极器件和光电耦合器位移损伤试验研究
Experimental study on displacement damage of aerospace bipolar and optocoupler devices
摘要
Abstract
To study the displacement damage effects, the proton accelerator and the neutron nuclear reactor are used to determine the displacement damage of compound semiconductor devices and silicon devices used for spacecraft. The curves of the degradation vs. the equivalent dose of the CTE of the GaAs optocpupler and the current amplification(hFE) of the silicon transistors are obtained. By analyzing the radiation test data for the optocoupler and the bipolar transistor, it is concluded that the displacement damage equivalence for the silicon devices is no longer valid for the GaAs compound devices, thus a correction is needed. Empirical correction coefficients are then determined according to the test data.关键词
