Abstract
The thin film AMA has a substrate, an actuator, a common line, and a reflecting member. The substrate has an electrical wiring and a connecting terminal and the actuator has a supporting layer, a bottom electrode, a top electrode, and an active layer. The common line is formed on a portion of actuator and is connected to top electrode. The electrical wiring and connecting terminal may not be damaged because actuator is formed on a portion of substrate adjacent to the portion where electrical wiring and connecting terminal are formed. The voltage drop of a second signal can be minimized because common line is formed thickly on a portion of actuator, so a sufficient second signal is applied to top electrode. The flatness of reflecting member may be enhanced because reflecting member is formed on a second sacrificial layer.
