ABSTRACT:
A semiconductor actuator includes a substrate base, a bending structure which is connected to the substrate base and can be deflected at least partially relative to the substrate base. The bending structure has semiconductor compounds on the basis of nitrides of main group III elements and at least two electrical supply contacts which impress an electrical current in or for applying an electrical voltage to the bending structure. At least two of the supply contacts are disposed at a spacing from each other respectively on the bending structure and/or integrated in the latter.
