In this paper, the annealing ambient dependences on the ferroelectric HfN1.15 formed by ECR-plasma sputtering was investigated. The annealing in He ambient suppressed frequency dispersion in C-V characteristics for Al/HfN0.5/HfN1.15/p-Si(100) MFS diode. The Tri-PUND results demonstrate that annealing in He ambient significantly increase the remnant polarization from 1.7 µC/cm2 to 8.1µC/cm2, which is high enough for metal-ferroelectric-Si field-effect transistor (MFSFET) application. |
