Patent ID: 6841081

Claim:
A method for manufacturing reflective spatial light modulator mirror devices, the method comprising: providing a substrate, wherein a first sacrificial layer and a mirror layer are formed in sequence to stack on the substrate; removing a portion of the mirror layer and a portion of the first sacrificial layer to form a plurality of openings in the mirror layer and the first sacrificial layer and to expose a portion of the substrate; forming a second sacrificial layer to cover the mirror layer, the first sacrificial layer, and the substrate; removing a portion of the second sacrificial layer to form a substrate contact opening in each of the openings and to at least form a mirror layer contact opening on the mirror layer; forming a support material layer to conformally cover the second sacrificial layer, the openings, the substrate contact opening, and the mirror layer contact opening; and performing an etching back step to remove a portion of the support material layer until exposing the second sacrificial layer.
