Patent ID: 8852345

Claim:
An apparatus for manufacturing an electronic device comprising: (a) a plurality of interconnected deposition vessels defining an elongated fabrication path; (b) means for advancing a substrate along the fabrication path; (c) at least one material deposition source positioned in each deposition vessel for depositing a material on the substrate when the substrate is positioned in the deposition vessel; (d) first and second cleaning vessels connected to each deposition vessel on respective first and second sides of the fabrication path, wherein each deposition vessel and the first and second cleaning vessels connected thereto define a cleaning path transverse to the fabrication path; and (e) means for translating first and second shadow masks from at least one deposition vessel and the second cleaning vessel connected to the at least one deposition vessel into the first cleaning vessel connected to the at least one deposition vessel and the at least one deposition vessel, respectively, and for translating the first and second shadow masks from the first cleaning vessel connected to the at least one deposition vessel and the at least one deposition vessel into the at least one deposition vessel and the second cleaning vessel connected to the at least one deposition vessel, respectively, wherein the first and second shadow masks have the same pattern of apertures.
