Method and apparatus for an actuator system having buried interconnect lines

An actuator system, comprising:

• a microelectromechanical (MEMS) structure comprising;
• an actuator body connected with a suspension system;
• and
• the suspension system connected with a set of layers, the suspension system being configured to elevate the actuator body above the set of layers upon actuation in a motion substantially perpendicular to the set of layers, the suspension system comprising a set of one or more flexures and a set of one or more torsional elements, wherein each flexure connects the actuator body with the set of layers and each torsional element connects a corresponding flexure with the actuator body and provides strain relief between the corresponding flexure and the actuator body, wherein each torsional element has a length comprising the distance from the corresponding flexure to the actuator body, the length being greater than the width of the torsional element;
• and
• the set of layers comprising:
• an electrode layer comprising a set of one or more electrodes for actuating the MEMS structure when a voltage is applied to the set of electrodes, each electrode having a skewed asymmetrical non-diamond shape and being located underneath the center of the actuator body and extending to a location underneath the edge of the actuator body;
• and
• an interconnect layer comprising a set of one or more interconnects coupled to the set of electrodes, the set of interconnects being coupled to a control circuit for controlling voltages applied to the set of electrodes via the set of interconnects, the interconnect layer being beneath the electrode layer.
