Surface Raman scattering can be enhanced by metal tip. There are few quantitative reports about the influence of tip angle on surface enhanced Raman scattering (SERS). In order to investigate the relationship between the tip angle and SERS, four kinds of samples with different tip angles, including 30°, 60°, 90°, 120° are fabricated by maskless projective lithography using digital micro-mirror device (DMD). The corresponding SERS spectra of the samples are measured, and influence of metal tip angle on SERS is investigated. Results show that acute angles have a better SERS effect, and the smaller the angle is, the more obvious the effect will be. Dependence on angle of SERS decreases in the case of obtuse angle.
