| Research Abstract |
Diamond-like carbon (DLC) coating was deposited on a micro/nano-trench by bipolar PBII, and the structure of the DLC film across the overall surface region of the trench was examined by making use of their corresponding Raman spectra. The plasma behavior in surrounding of the trench was calculated with Particle-In-Cell Monte Carlo Collision Method. As a result, DLC film was successfully coated on the overall surface of the trench. When the applied negative voltage was -0.5 kV, the structure of DLC film on the trench-sidewall became more polymer-like carbon than those of the top and bottom surfaces did. This is because the ions, which strike the sidewall, tend to have less incident energy. Whereas in the case of -15 kV, the DLC film on the sidewall was more graphite-like, despite of its smaller incident ion energy in comparison to those of the top and bottom surfaces. This is attributed to sputtering effect from the bottom surface of the trench, as evidenced by the plasma simulation.
