Abstract
The present invention includes a structure, apparatus, and method by which the reflectivity of a micro-machined reflector can be improved. The present invention increases the mirror's reflectivity at 650 nm, increases its reflectivity at 410 nm, and improves its long-term reliability. The reflectivity at other wavelengths may also be improved. Also, the present invention minimizes mirror plate distortion while providing a suitable fabrication approach.
