Abstract
A process for fabricating a micromechanical structure made of silicon carbide including a cavity, from a stack including a first silicon-carbide layer and a silicon layer on the first silicon-carbide layer, the process including shaping the silicon layer so as to form a discrete silicon structure on the first silicon-carbide layer. The process further includes, after the shaping of the silicon layer, a carbonization to initiate the removal of the discrete silicon structure; depositing a second silicon-carbide layer; and an annealing step, the discrete silicon structure being entirely removed at the end of the annealing.
