Patent ID: 8097483

Claim:
A method for manufacturing a MEMS element on a substrate, the MEMS element comprising a first electrode and a second electrode, the first and second electrodes being separated by a cavity, the substrate comprising an insulating surface layer; wherein the method comprises: creating the first electrode on the insulating surface layer; creating a first metal body and a second metal body in a second metal layer, the first and second metal bodies being separated from each other by an intermediate separation, the first metal body being located above an anchor location, the second metal body being located above at least the first electrode, creating as the second electrode a beam-shaped body in a third metal layer located on the first metal body and at least a portion of the second metal body; creating at least one opening in the third metal layer to the second metal body in an area above the second metal body; and removing the second metal body through the at least one opening so as to create a cavity in the location of the second metal body.
