Description

Radiation damage,caused by high or low dose rate irradiation, to NPN transistors of different oxide thicknesses is investigated experimentally. The results show that base current of the transistors increased with total dose, but the current gain decreased with increasing total dose. The NPN transistors of thin oxides degraded more than those of ordinary oxide thickness. However, both types of the NPN transistors exhibited the enhanced low dose rate sensitivity (ELDRS). Mechanisms of the effects are discussed. (authors)
