Abstract:
1. A micro-electromechanical device comprising: a first dielectric layer; a buried conductive trace disposed over the first dielectric layer, such that the buried conductor trace is electrically connected to a power source; a second dielectric layer disposed over the buried conductive trace, the second dielectric layer comprising one or more vias that extend up to the buried conductive trace, wherein the buried conductive trace is disposed between the first dielectric layer and the second dielectric layer; at least one conductive electrode disposed over the second dielectric layer and electrically connected to the buried conductive trace through the one or more vias; and at least one conductive membrane comprising membrane anchors disposed over the second dielectric layer, such that the at least one conductive membrane is electrically isolated from the at least one conductive electrode and the buried conductor trace and the at least one conductive electrode is within a sealed chamber, wherein the sealed chamber is disposed below the at least one conductive membrane, wherein the at least one conductive membrane is capable of being deflected by a voltage being applied to the at least one conductive electrode, and wherein the at least one conductive electrode is electrically connected to the power source through the buried conductive trace.
