Dear fellow MEMS Researchers, in a previous question I asked for a fraktal Gold Surfaces. Now I'm experimenting with black silicon, what I'm producing in a RIE-Process (SF6 & O2). But the average Roughness of this black silicon is too low - mainly if I sputter Ti/Au on it. Has anyone an idea to increase the roughness? Which parameters can I use?
