Abstract

A process for producing micro-mechanical structures for sensors or actuators is proposed. Here, local oxidations are placed into the surfaces of at least two wafers with the aid of masking technology, so that level wafer surfaces are generated. The at least two wafers are subsequently connected with each other in such a way that the local oxidations of the at least two wafers are in direct contact. The actual sensor structure, which might possibly be mechanically deformable, is exposed by dissolving the local oxidations out.
