Patent ID: 6952303

Claim:
A method of manufacturing an interferometric modulation pixel, comprising: forming a first electrode layer on a transparent substrate, wherein an uppermost layer of the first electrode layer is an insulating layer; forming a protection layer on the insulating layer forming a sacrificial layer on the protection layer; forming at least two first openings in the sacrificial layer, the protection layer and the first electrode layer to demarcate and define a first electrode, wherein the first electrode is made from the first electrode layer; coating a photosensitive material on the sacrificial layer and in the first openings; patterning the photosensitive material to form supports in the first openings; forming a second electrode layer on the sacrificial layer and the supports; forming at least two second openings in the second electrode layer to define a second electrode, wherein the second electrode is made from the second electrode layer and the orientation of the second openings is perpendicular to the two first openings; and removing the sacrificial layer.
