    In the study, we reduced the operation current of resistance random access memory (RRAM) by supercritical CO(2) (SCCO(2)) fluids treatment. The power consumption and joule heating degradation of RRAM device can be improved greatly by SCCO(2) treatment. The defect of nickel-doped silicon oxide (Ni:SiO(x)) was passivated effectively by the supercritical fluid technology. The current conduction of high resistant state in post-treated Ni:SiO(x) film was transferred to Schottky emission from Frenkel-Pool due to the passivation effect. Additionally, we can demonstrate the passivation mechanism of SCCO(2) for Ni:SiO(x) by material analyses of x-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy.
