Abstract:
1. A movable micro-device comprising: a movable part including a movable main portion, a first capacitor comb-teeth electrode and a first driver comb-teeth electrode, the first capacitor comb-teeth electrode having a plurality of electrode teeth extending from the movable main portion, the first driver comb-teeth electrode having a plurality of electrode teeth extending from the movable main portion; a frame including a second capacitor comb-teeth electrode and a second driver comb-teeth electrode, the second capacitor comb-teeth electrode having a plurality of electrode teeth extending toward the first capacitor comb-teeth electrode, the second driver comb-teeth electrode having a plurality of electrode teeth extending toward the first driver comb-teeth electrode; and a connecting part connecting the movable part and the frame to each other; wherein the first and the second capacitor comb-teeth electrodes are made of a metal material and have electrode teeth overlap in an initial position, wherein the first and the second driver comb-teeth electrodes are made in a same material layer and arranged not to overlap each other in an initial position, wherein the first and the second capacitor comb-teeth electrodes are made in a layer different from said same material layer in which the first and the second driver comb-teeth electrodes are made, and wherein the movable part is rotatable for varying an extent of the electrode teeth overlap between the first and the second driver comb-teeth electrodes.
