摘要： An optical scanner and a fabricating method thereof are provided. The optical scanner includes a base substrate, a frame, a H-shaped stage, supporters, and a stage driving structure. An interconnection layer having a predetermined pattern is formed on the base substrate. The frame has a rectangular frame shape which is formed on the base substrate. The H-shaped stage has a central area that performs a seesaw motion in the frame with respect to a uniaxial central axis and is positioned on the uniaxial central axis, and four extended areas that extend from two sides of the central area through which the uniaxial central axis passes, parallel the uniaxial central axis. The supporters have support beams that are positioned on the uniaxial central axis and connected to the frame and torsion bars that extend from the support beams and are connected to the central area of the stage. The stage driving structure has moving comb electrodes and fixed comb electrodes beneath the stage and on the base substrate facing the stage, respectively. A plurality of comb electrodes can be formed on the extended areas. Thus, a driving force can greatly be increased, which results in obtaining a similar driving speed using a considerably low voltage. Also, the weight of the stage should greatly be reduced for high-speed driving. For this, the stage is diced into a plurality of stages. Further, to increase the driving force, a plurality of comb electrodes are additionally formed on right and left sides of the stage.
