Patent ID: 8247945

Claim:
A micro-electro-mechanical transducer having a movable mechanical part to transform energy, the transducer comprising an addressable device element having a device element periphery defining a device element area, wherein the addressable device element comprises: a substrate; a top plate layer disposed above the substrate; and a resilient structure between the substrate and the top plate layer, wherein: the resilient structure has a lower portion connecting to the substrate and an upper portion connecting to the top plate layer; the upper portion of the resilient structure has a plurality of connectors connecting to the top plate layer; the plurality of connectors are distributed over the device element area and have at least one connector located substantially away from the device element periphery toward an inner region of the device element area; the top plate layer is located over the connectors to define a transducing space below the top plate layer; the addressable device element has at least one transducing member to induce energy transformation; and the resilient structure enables a vertical displacement of the plurality of connectors to transport the top plate layer in a substantially vertical direction, thus changing the transducing space and activating the transducing member, wherein: the transducer comprises a plurality of the addressable device elements; and the plurality of addressable device elements are separated by a separation trench formed into at least part of the top plate layer.
