Abstract:
1. A MEMS device operable for modulating light having fluorosurfactant lubricated moving parts, comprising: a silicon substrate consisting of an array of CMOS memory circuits; a planarized thick oxide isolation layer deposited on top of said substrate; metal yoke address electrodes and landing pads fabricated over said planarized isolation layer; a rotating yoke assembly attached to thin metal torsion hinges, said hinges supported by hinge posts extending above said landing pad metal; mirror address electrodes attached to top of additional posts extending above said yoke address pads; and highly reflectively metal mirrors mounted to mirror posts attached to and extending above said rotating yoke assembly, wherein surfaces of said MEMS device are lubricated to prevent sticking by means of a fluorosurfactant nebulization, said fluorosurfactant containing a water-like hydrophillic chain attached to a hydrophobic fluorocarbon.
