In comparison with miniature XY-stage in terms of driving methods: electrostatic, electromagnetic and piezoelectric actuators, the piezoelectric actuators have high area efficiency but no machinability by conventional microfabrication techniques. In this paper we have proposed the novel fabrication method of a double-layered piezo-stack actuator made from a monolithic PZT plate based on a planer fabrication method, and integrated the actuators into a XYZ-stage with six degrees of freedom, i.e., X, Y, X, θx, θy and θz directions. The stacked piezoactuators were formed on the both side of the PZT plate. The double stacked-piezoactuators, which are arranged around the stage, can stretch in plane or bend to Z-direction. The fabrication method includes dicing, electroplating, and laser machining. After making grooves by dicing, metal electroplating was performed and buried Ni into the grooves, which was done on both side of the PZT plate. After polishing the surface, metal electrodes were formed on an insulating photosensitive polyimide layer. Finally, the complete structure was defined by laser machining. The test results show that the X direction displacement of the actuation arms was about 2 μm when 40 V was applied to both of double-layered piezo-stacked actuators. The Z direction displacement of the actuation beam was about 2 μm when 40 V was only applied to one stacked actuator. These results show the possibility of the microstage with six degrees of freedom.
