  • Diffractive thin-film piezoelectric light modulator and method of fabricating the same
    Publication number: 20060113869
    Abstract: Disclosed herein is a diffractive thin-film piezoelectric light modulator, in which a lower protective layer is formed on a lower support to prevent the lower support from being over-etched when etching, thus increasing the surface smoothness of the lower support and of a micro-mirror. In addition, a method of fabricating the diffractive thin-film piezoelectric light modulator is also provided.
