Abstract
A MEMS micro-mirror device includes a middle substrate, a movable structure, at least one stopper coupled with the movable structure, at least one flexure, an upper cap, and a lower cap. The movable structure includes a micro-mirror plate having a reflective surface. The flexure connects the stopper and the middle substrate. The upper cap, bonded with the middle substrate, has a first opening for allowing the movable structure's movement and has at least one first recess facing a first side of the flexure and a first side of the stopper. The lower cap, bonded with the middle substrate, has a second opening for allowing space for the movement and has at least one second recess facing a second side of the flexure and a second side of the stopper.
