Structure of DMD
• Mirror fabricated of aluminum.
DMD Mechanical System
• Rotation of the mirror is accomplished through electrostatic attraction
produced by voltage differences developed between the mirror and the
underlying memory cell.
- Mechanical switching time : ~15 us, Optical switching
time : ~ 2us
* The mirror and yoke are connected to a bias/reset voltage. The address
electrodes are connected to the underlying CMOS memory through via contacts.
Movement of the mirror is accomplished by storing a 1 or a 0 in the memory cell
(one address electrode at ground and the other address electrode at VDD) and
applying a bias voltage to the mirror/yoke structure.
