  • Abstract
    We show how it was possible to develop an etching process of SiGe with a high selectivity to similar materials such as nitride, oxide and even pure silicon. The study of the material and process parameters has lead to an understanding of the etching mechanisms and permitted to control the selectivity so as to improve or invert it, which gave rise to new ideas of integration.
