摘要： A method of fabricating a zinc oxide (ZnO) thin film in which the surface shape of the ZnO thin film can be controlled during deposition of the ZnO thin film. The method includes depositing the ZnO thin film on a substrate by chemical vapor deposition (CVD). The CVD feeds an etching gas that etches the ZnO thin film concurrently with a source gas and an oxidizer gas, thereby controlling the surface shape of the ZnO thin film that is being deposited.
