Claim:
1. A production method for a micromechanical component, comprising: forming a catalyst layer on an upper side of a silicon on insulator substrate, the catalyst layer suitable for promoting silicon growth of the upper side, the substrate including a first silicon layer, an oxide layer, and a starting layer that has exposed structure regions, the structure regions defined by the upper side and lateral flanks, with no catalyst layer formed on the lateral flanks; performing a selective growth process on the upper side of the exposed structure regions of the starting layer via the catalyst layer in a reactive gas atmosphere to form a micromechanical functional layer; and removing at least a portion of the oxide layer of the substrate via sacrificial layer etching such that at least a portion of the micromechanical functional layer is movable relative to the substrate.
