A method of fabricating a micro-electrical-mechanical system (MEMS) apparatus on a substrate comprises the steps of processing the substrate so as to fabricate an electronic circuit; depositing a first electrode that is operably coupled with the electronic circuit; depositing a membrane so that it is mechanically coupled to the first electrode; applying a sacrificial layer; depositing a structural layer and a second electrode that is operably coupled with the electronic circuit so that the sacrificial layer is disposed between the membrane and the structural layer so as to form a preliminary structure; singulating the substrate; and removing the sacrificial layer so as to form a MEMS structure, in which the step of singulating the substrate is carried out before the step of removing the sacrificial layer. |
