Patent ID: 8749868

Claim:
An apparatus for fabricating an electrochromic device, comprising: (a) an integrated deposition system comprising: (i) a first deposition station containing a first target comprising a first material for depositing a layer of an electrochromic material on a substrate when the substrate is positioned in the first deposition station, and (ii) a second deposition station containing a second target comprising a second material for depositing a layer of a counter electrode material on the substrate when the substrate is positioned in the second deposition station; and (b) a controller containing program instructions provided on a non-transitory medium for passing the substrate through the first and second deposition stations in a manner that sequentially deposits a stack on the substrate, the stack comprising the layer of electrochromic material in direct contact with the layer of counter electrode material, without an ion conducting layer between the layer of electrochromic material and the layer of counter electrode material.
