本研究中，我們以磁控式射頻濺鍍機(RF Sputter)來製作氧化銅及氧化亞銅薄膜，首先以純銅(99.99%)靶材進行濺鍍，並在腔體中通入氧氣及氬氣，分析銅在氧氣比例的不同之下對我們所形成的薄膜在光性、電性、表面結構上所造成的影響。
實驗發現在氧氣比例20%以上時為單一晶相的氧化銅薄膜，且此後20%~80%的氧氣比所製作出來的薄膜在各種特性下的表現均不會造成太大的變化；在10%及12%低氧氣比例下可以發現薄膜成分為多晶(Cu2O and CuO)；當氧氣比例為8%時，實驗結果為單一晶相的氧化亞銅薄膜，電阻率達6x102 Ω-cm。

In this study, copper oxide (I)(II) thin film is prepared by magnetron RF sputtering. The effect of oxygen ratio and RF power during sputtering on the optical, electrical, and surface characteristics of the copper oxide film was discussed. Single phase CuO was formed when the oxygen ratio was up to 20%. Mixed phase cupper oxides including CuO and Cu2O were formed under the condition of oxygen ratio lower than 10% and 12%.Under the condition of 8% oxygen ratio, single phase Cu2O was formed with resistivity of 6x102 Ω–cm and band gap of 2.1eV.
