Abstract
A microelectromechanical actuator structure including a microelectromechanical chip having a chip frame and a drive structure. The drive structure includes a first drive unit and a second drive unit. The first drive unit includes a first substrate and a first electrode structure. The first substrate has a first doping. The first electrode structure has a doping inverse to the first doping. The second drive unit includes a second substrate having a second doping and a second electrode structure having a doping inverse to the second doping. A pn junction is therefore formed between the substrates and the second electrode structures. The first electrode structure includes at least two first electrodes. The second electrode structure includes at least one second electrode. The first electrodes are arranged flat next to one another in a first electrode plane. The second electrode is arranged flat in a second electrode plane.
