Patent ID: 8169678

Claim:
A method for producing a micro-mirror actuator, which has, in an inner area, at least one movable micro-mirror element and multiple finger-shaped or comb-shaped electrodes for activating the micro-mirror element, which are offset to one another in height, wherein a layered construction made of at least three main layers ( 101 , 103 , 107 ) is generated, which are at least sectionally electrically insulated from one another via intermediate layers ( 102 , 104 , 106 ), and the layers are designed and structured to form the micro-mirror element and the electrodes, the structuring of the layers being performed in such a way that a closed frame ( 310 ) is obtained from at least the uppermost layer ( 107 ), which encloses the inner area of the actuator and allows a hermetic encapsulation of the inner area by application of a cover plate on the frame ( 310 ), and, during the generation of the layered construction, a conductor level ( 105 ), which is electrically insulated from these main layers via the intermediate layers, is generated between at least two of the main layers and structured to form conductor paths, which allow electrical contact to one or more of the electrodes from outside the frame ( 310 ) after the formation of contact openings in one or more of the intermediate layers ( 102 , 104 , 106 ).
