Scanning etching manufacture is a nanofabrication method based on microplasma etching and parallel probe actuation.The piezoelectrical microcantilever is the key component of the system.The residual stress generated during the fabrication process will cause the microcantilever bending and affect the performance of system.A theoretical model of microcantilever considering residual stress is developed based on elastic plate theory and verified with FEM.Combined with taguchi method
the optimal design on the thickness of multi-layer is carried out.
