Nanostructured metals with designable and controllable structure have received increasing attention in surface enhance Raman scattering (SERS) due to single molecular detection limmit. While great challenge remains in creating large scale substrate with high-density "hotspots" to provide uniform and stable enhancement of Raman signals. Here, we fabricated copper island thin film over eighty square centimeter-scale substrate with tunable particle sizes by combining sputtering with dealloying processes. The island size can be tailored from 150 nm to 370 nm by
