A micro XY-stage with a 5 5 mm 2 -area shuttle is fabricated for application in a nanometer-scale data storage device. A central shuttle of the device is designed as a large square on which a high-density recording medium is deposited. Perpendicularly combined comb-drive actuators allow the large shuttle free access in the x-y plane. No etching holes on the central shuttle are preferred in order to maximize the effective recording area. Therefore, a novel release process, Micro-Channel Assisted Release Process ( CARP) is proposed to release a large plate structure without any etching holes and to resist downward sticking. The static and dynamic strokes of the device were measured. Mechanical interferences between x-and y-directional drives were estimated by finite-element method (FEM) analysis and compared with the experimental results.[876]Index Terms-High-density storage, large area shuttle, micro XY-stage, scanning probe microscopy (SPM), micro-channel assisted release process ( CARP).
