英文摘要The radiation effects of magnetic tunnel junction (MTJ) in a 180 nm Magnetoresistive Random Access Memory (MRAM) were investigated at the condition of the high heavy ion fluence (up to 10(10) ions center dot cm(-2)) and high gamma-ray dose (up to 15 Mrad(Si)), respectively. The Hard Bit Error (HBE) was only observed when the energy of Ta-181 ions was larger than 95.8 MeV under the ion fluence of 10(9) ions center dot cm(-2) (similar to 13 ions center dot bit(-1)). For gamma-ray exposure, no obvious effects were observed in devices. The HBE counts induced by Ta-181 ions have a strong dependence on ion energy and cumulative fluence. In addition, the annealing characteristics of HBE after heavy ion irradiation at room temperature were also observed. It is found that the high ambient temperature is able to accelerate this annealing process. Monte Carlo simulation by using TRIM program revealed that the displacement damages induced by heavy ions were mainly located in the insulating layer of MTJ, which is responsible for the occurrence of HBE.
