Copper thin films with low electrical resistivity were successfully deposited by filtered cathodic vacuum are technique at room temperature. The structure of the films was determined by X-ray diffraction, TEM and atomic force microscopy. All the copper films had a polycrystalline structure. The RMS roughness, the lateral size and the grain size all increased with increasing film thickness. There is a critical film thickness of approximately 135 nm. The electrical resistivity had an almost unchanged value of 1.8 μΩ cm. above 135 nm and increased with decreasing thickness below 135 nm.
