The ITA treatment is performed by Co-60 irradiation with a suitable dose followed by annealing in pure nitrogen at 400°C for 10 min. It is found that samples receiving ITA treatments exhibit better performance in oxide properties than those not receiving an ITA treatment. For the examination of oxide leakage current, the charge-then-decay method is employed. Devices with two ITA treatments exhibit a very slow gate voltage decay behavior even in a moist environment. Both the radiation hardness and the hot-carrier resistance are improved by the ITA treatment. The gate area dependence and the total dose effect in ITA treatment are also discussed. © 1992 The Japan Society of Applied Physics. |
