Abstract

ZnO thin films are deposited on $SiO_2$/Si (111) substrate by RF magnetron sputtering. The two-step deposition method is proposed to enhance both the c-axis orientation and the resistivity of ZnO films. This method consists of the following two procedures: the 1 st-deposition for 30 min without oxygen at l00W and the 2nd-deposition with oxygen added in the range of $O_2/(Ar+O_2)=10{\sim}50%$. Effects of thermal treatment on the properties of ZnO films are systematically investigated.
