Patent ID: 7527995

Claim:
A method of forming an interferometric display element, comprising: providing a substrate; depositing a layer of support post material over the substrate; patterning the layer of support post material to form at least two support posts; depositing an electrode layer over the substrate, wherein the depositing of the electrode layer is performed after the forming of the at least two support posts, and wherein at least a first portion of the electrode layer is located between the at least two support posts; forming at least a first sacrificial layer over at least the first portion of the electrode layer; forming a mechanical layer over the sacrificial layer, wherein the mechanical layer covers a portion of each of the at least two support posts; and removing at least a portion of the first sacrificial layer after formation of the mechanical layer, wherein removal of at least a portion of the first sacrificial layer allows a portion of the mechanical layer extending between the at least two support posts to be displaced with respect to the first portion of the electrode layer.
