The next resonance mode is rotation around vertical axis. Design of the micro-mover provides about 15X separation between the main resonance and this mode. 2. DESIGN AND FABRICATION OF ACTUATED CANTILEVERS A two-dimensional array of cantilevers formed on CMOS wafer is located in close proximity to the side of the X–Y micro-scanner carrying the memory stack. Each cantilever carries a sharp tip used as a read–write head. The array of cantilevers (see Figure 10) is fabricated using a low-temperature post-CMOS process utilizing SiGe as a structural material .

The background polarization of a freshly as-grown PZT is poled naturally to an UP state (as characterized by piezoresponse force microscopy (PFM) ). 1. WRITE OPERATION Writing of ferroelectric domains of alternating polarity in a PZT media using a train of voltage pulses applied to a probe tip was used for characterization of write operation capabilities. The tip moves in contact with the media surface at the velocity synchronized with the pulse train frequency to write an array of alternating polarization domains (bits) of desired pattern wavelength.
