ZnO thin films on glass substrate were deposited by on RF mangetron reaction sputter with various grgon/oxygen gas ratios and sbustrate temperatures. Crystallinities, surface morphologies, chemical compositions, and electrical properties of the films were investigated by XRD, AFM, XPS, RBS, and electrometer(keithley 617). All films showed a strong perferred orientation along the x-axis on glass substrate, and the chemical stoichiometry of Zn/)=1/1.0 was obtained at Ar/$O_2$ =50/50. Surface roughness and resistivity depended on the argon/oxygen gas ratio. The minimum surface roughness of 20$\AA$ and maximum resistivity of $10^8$ $\Omega$ cm were achieved at Ar/$O_2$=10/90.
