Claim Text:
1. A method of forming a substrate pair assembly, comprising: providing a first optically transparent substrate and a second optically transparent substrate; depositing a first layer of metal material on the first optically transparent substrate; forming a first layer of metal oxide material wherein the metal oxide is the oxidation product of the metal material and the first optically transparent substrate, and is formed during the depositing of the metal material; patterning the first layer of the metal material to create a metal feature; forming a second layer of metal oxide material, wherein the second layer of metal oxide is the oxidation product of the metal material and the second optically transparent substrate; and is disposed between the second optically transparent substrate and the metal feature, wherein the layer of metal material and the first and second layers of metal oxide form a first anodic bond between the first optically transparent substrate and the second optically transparent substrate and forming a first layer of a second bonding material on at least one of the first and the second optically transparent substrate, and patterning the first layer to form a first feature of the second bonding material; and bonding the first optically transparent substrate to the second optically transparent substrate with a second bond of the second bonding material.
