Patent ID: 8445976

Claim:
A micro movable device, comprising: a support substrate; a signal line formed on the support substrate; a ground line formed on the support substrate and arranged side by side with the signal line; an insulating layer formed so as to cover the signal line and the ground line; a first driving electrode formed on the insulating layer and above the signal line; a second driving electrode formed on the insulating layer and above the ground line, the second driving electrode being arranged side by side with the first driving electrode; a first auxiliary driving electrode arranged side by side with the first driving electrode; a second auxiliary driving electrode arranged side by side with the second driving electrode; and a movable electrode which is formed above the first driving electrode, the second driving electrode, the first auxiliary driving electrode and the second auxiliary driving electrode with a space provided between the movable electrode and the first driving electrode, the second driving electrode, the first auxiliary driving electrode, and the second auxiliary driving electrode, the movable electrode being supported on the support substrate.
