In this paper the results of modeling and simulation of NBTI effects in p-channel power VDMOS transistor have been presented. Based on the experimental results, the threshold voltage shifts and changes of transconductance during the NBT stress have been modeled and implemented in the PSPICE model of the IRF9520 transistor. By predefining the threshold voltage value before the NBT stress, and by assigning the stress time, transfer characteristics of the transistor are simulated. These characteristics are within (1.33?11.25)% limits in respect to the measured ones, which represents a good agreement.

Gamma Ray Irradiation

The variations in the threshold voltage shift in p-channel power VDMOSFET during the gamma ray irradiation was investigated in the dose range from 10 to 100 Gy. The investigations were performed without the gate bias and with 5 V gate bias. The devices with 5 V gate bias exhibit a linear dependence between the threshold voltage shift and the radiation dose. The densities of radiation-induced fixed and switching traps were determined from the sub-threshold I-V characteristics using the midgap technique. It was shown that the creation of fixed traps is dominant during the irradiation. The possible mechanisms responsible for the fixed and switching traps creation are also analyzed in this paper.
