Abstract:
Micromechanical motion facility with the following characteristics:a first semiconductor wafer (2), an oxide layer (14) on the first semiconductor wafer (2), where the first semiconductor wafer (2) is formed in such a way as to form arrays (5) of micromechanical, flexible, one-piece bandlike elements (6), which are arranged parallel to each other, one array (5) consists of at least one carrier and several elements (6), first bandlike electrodes are mounted on these elements (6) which simultaneously serve as reflection layer (10), these first bandlike electrodes are mounted on the oxide layer (14) on the opposing side of the first semiconductor wafer (2), and where at least one swivel bearing is integrated in the elements (6), a first electrical insulation layer (3) on the side of the oxide layer (14) across from the semiconductor wafer (2), where arranged on the first electrical insulation layer (3) corresponding to the edges of the elements (6) are at least one second electrode (11) as well as feeder lines (12) which serve as electrical connection between the second electrodes (11) and bondpads (4), the first electrical insulation layer (3) has windows (13, 20) for the bondpads (4) and for adjustment marks (22), which are located on the edge of the first semiconductor wafer (2), and where the windows (20) for the adjustment marks (22) have a layer of the second electrodes (11) and feeder lines (12), several support elements (9) created by purposeful undercutting of the elements (6) from the oxide layer (14) on the swivel bearings between the elements (6) and the first insulation layer (3), a second insulation layer (15) on the first insulation layer (3) and a second semiconductor wafer (17) with an oxide layer (16), where the oxide layer (16) of the second semiconductor wafer (17) is connected to the second insulation layer (15).
