Abstract:
1. A method of making an optical microelectromechanical system (MEMS) device, comprising: forming a first electrode of the optical microelectromechanical system device; providing a dielectric layer over the first electrode; providing a sacrificial layer over the dielectric layer; forming a second electrode over the sacrificial layer; removing the sacrificial layer after forming the second electrode; providing a plurality of pre-formed particles; and depositing the plurality of pre-formed particles on the sacrificial layer after providing the plurality of pre-formed particles, after providing the sacrificial layer and before forming the second electrode, wherein the plurality of pre-formed particles have a diameter between about 10 Å and about 500 Å, wherein forming the second electrode comprises transferring a texture from the pre-formed particles on the sacrificial layer into a surface of the second electrode deposited over the sacrificial layer.
