Abstract:
1. A method for fabricating an optical interference display unit disposed on a transparent substrate, the method comprising: forming a first electrode on the transparent substrate; forming a support structure; forming a first material layer over the support structure; forming a second material layer over the first material layer; forming a patterned photoresist layer over the second material layer; using the patterned photoresist layer as a mask to etch the second material layer to expose the first material layer; stripping the patterned photoresist layer, using the first material layer to protect the support structure; and using the second material layer as a mask to etch the first material layer to expose the support structure, wherein the first material and the second material layers form a second electrode of the optical interference display unit, and the second electrode is a movable electrode, an edge of the second electrode supported by the support structure.
