Abstract

La présente invention porte sur un dispositif à micromiroirs optiques et son dispositif matriciel et son procédé de fabrication. Grâce à l'introduction d'une couche de sous-revêtement et une couche de revêtement externe avec une couche de métal fortement réfléchissante, la couche réfléchissante des micromiroirs est protégée de l'environnement, d'une oxydation, d'une dégradation, des acides, des bases, et d'une corrosion galvanique des structures micromécaniques. De même la nouvelle structure d'enduction améliore les performances du dispositif matriciel à micromiroirs en réduisant la dégradation de la réflectivité de la couche de métal, en produisant un effet anti-reflet dans la zone non efficace optiquement, et en protégeant les structures micromécaniques.
