    The reactive ion etching technique was used to etch polycrystalline diamond thin films. In the first concept we investigate the influence of process parameters (total pressure, rf power, gas composition) of standard capacitively coupled plasma (CCP) system (Phantom III, Trion Technology) on the etching rate of diamond films. In the second concept, we focus on using a linear-antenna microwave plasma system (AK400, Roth&Rau) for diamond etching. We found that the gas composition in the CCP plasma system had a crucial effect on the film morphology. Using of CF4 gas resulted in more flat surfaces and lateral-like etching, while using of pure O2 gas formed needle-like structures. Adding of argon to the reactant precursors increased the ion bombardment, which increased the formation of non-diamond phases,etc.
