플라즈마 화학 증착법으로 (100)p-type Si wafer위에 $Y_2O_3$-Stabilzed $ZrO_2$박막을 증착하였다. 반응 기체로는 zirconium triflouracethylacetonate[Zr(tfacac) $[Zr(tfacac)_4]$, tri(2.2.6.6 tetramethy1-3, 5-heptanate) yttrium $[Y(DPM)_3]$과 oxygen gas를 사용하였다. X-ray diffraction(XRD)과 fourier Particle induced x-ray emission(PIXE)을 통하여 $Y(DPM)_3$ bubbling temperature가 $160^{circ}C, 165^{circ}C, 170^{circ}C$일때 $Y_2O_3$함량이 12.1mo1%, 20.4mol%, 31.6mol%임을 알 수 있었다. C-V측정에서 $Y(DPM)_3$ bubbling temperature가 증가함에 따라 flat band voltage가 더욱더 음의 방향으로 이동하였다.
Yttria-stabilized zirconia(YSZ) films were prepared onto p-type (100) silicon wafer by a plasma-enhanced metallorganic chemical vapor deposition(PE MO CVD) processing involving the application of vapor mixture of tri(2.2.6.6-tetramethyl-3, 5-heptanate) yttrium$[Y(DPM)_3]$, zirconiumtriflouracethyla cetonate$(Zr(tfacac)_4$ and oxygen gas. The x-ray diffraction(XRD) and fourier transform infrared spectra(FT1R) results showed that the deposited YSZ films had a single cubic phase. $Y_2O_3$ content of YSZ film was analyzed by PIXE(partic1e induced x-ray emission). The experimental results by PIXE revealed that 12.lmol%, 20.4mol% and 31.6mol% $Y_2O_3$ could be obtained as the $Y(DPM)_3$ bubbling temperature varied at $160^{circ}C, 165^{circ}C$ and $170^{circ}C$ respectively. The increase of $Y(DPM)_3$ bubbling temperature caused shifting flat band voltage to have a negative value.
