This study included a different weight ratio of copper (2, 4, 6, 8) wt% as a dopant, with tin oxide SnO2 deposits on glass substrate by RF reactive magnetron sputter. The structural properties show polycrystalline pattern nature for all deposit samples with dominated reflection (110). The electrical conductivity increased to 1×13010 S-1 and the optical conductivity to 35×1016 S-1. The energy gap decreased to 3.60 eV when the rate of deformation was 8wt%, due to the increase in the crystallite size to 24.5 nm with the improvement of crystallization. While the surface measurements showed an increase in the surface roughness to 50 nm when the rate of deformation at 8wt%.
