| Abstract: | Anisotropic wet-chemical etching of silicon in alkaline solutions is a key technology in the fabrication of sensors and actuators. In earlier work it was found that not only the etchant and temperature determine the exact anisotropy of etched silicon; the angle between the silicon surface and the mask was also shown to play an important role. In this paper this phenomenon was quantified for several etching conditions. Also, the etch rates of Si |
