Popis: | Silicon reactive ion etching using a mixture of SF"6 and CHF"3 at room temperature was investigated. The etching characteristics as a function of gas composition, rf power, pressure and masking material as well as electrode material were studied. Highly anisotropic, vertical and with smooth surface silicon pillars, lines and trenches with aspect ratios as high as 25:1 with dimensions down to 50 nm were obtained |
