Abstract:
A thin film actuated mirror array being actuated by a first signal and a second signal, said thin film actuated mirror array comprising:an active matrix having a substrate including a metal oxide semiconductor transistor installed therein for a switching operation and a first metal layer having a drain pad prolonged from a drain of the metal oxide semiconductor for transmitting the first signal;a supporting means having a supporting line formed above said active matrix, a supporting layer integrally formed with said supporting line and a plurality of anchors respectively formed between said active matrix and portions of said supporting layer adjacent to said supporting line;a first actuating part having a first bottom electrode for receiving the first signal, said first bottom electrode being formed at a first portion of said supporting layer formed perpendicular to said supporting line, a first top electrode corresponding to said first bottom electrode for receiving the second signal and generating a first electric field, and a first active layer formed between said first bottom electrode and said first top electrode and deformed by the first electric field;a second actuating part having a second bottom electrode for receiving the first signal, said second bottom electrode being formed at a second portion of said supporting layer formed perpendicular to said supporting line, a second top electrode corresponding to said second bottom electrode for receiving the second signal and generating a second electric field, and a second active layer formed between said second bottom electrode and said second top electrode and deformed by the second electric field;a reflecting means for reflecting a light, said reflecting means being formed above said first actuating part and said second actuating part; andflatness enhancing means for enhancing a flatness of said reflecting means, said flatness enhancing means being formed beneath said reflecting means, said flatness enhancing means being a stress balancing layer formed beneath said reflecting means.
