Ferroelectric Bi4 − xNd x Ti3O12(BNdT) thin films with the composition (x = 0.75) were prepared on Pt/Ti/SiO2/Si(100) substrate by metal-organic deposition. The films were annealed by various temperatures from 550 to 650C and then the electrical and structural characteristics were investigated for the application of FRAM. Electrical properties such as dielectric constant, 2Pr and capacitance were quite dependent on the thermal heat treatment. The measured 2Pr value on the BNdT capacitor annealed at 650C was 56 μ C/cm2 at an applied voltage of 5 V. No fatigue was observed up to 8 × 1010 read/write switching cycles at a frequency of 1 MHz regardless of annealing temperatures.
