Smooth silicon sidewall etching for waveguide structures using a modified Bosch process

, 2014
We present a method to etch vertical and smooth silicon sidewalls. The so-called modified Bosch process combines a passivation step, a breakthrough step, and an anisotropic etch step within one repeatable loop.
