Patent ID: 6929969

Claim:
A method of fabricating micromirrors comprising: forming a first sacrificial layer overlying a substrate; depositing a mirror layer overlying said first sacrificial layer; patterning said mirror layer to form first openings in said mirror layer, at least one of said first openings surrounded by said mirror layer; forming a second sacrificial layer overlying said mirror layer and within said first openings; a patterning said second sacrificial layer to form hinge openings to said mirror layer and patterning said second and first sacrificial layers to form post openings within said first openings; forming support posts within said post openings and hinges within said hinge openings wherein each of said hinges is connected to said support posts; thereafter patterning said mirror layer to form a plurality of said micromirrors wherein each of said plurality of micromirrors is attached on one end to one of said hinges through said hinge openings; and removing said first and second sacrificial layers to complete fabrication of said micromirrors.
