WEB SUBSTRATE DEPOSITION SYSTEM

A web substrate atomic layer deposition system includes at least one roller that transports a surface of a web substrate through a plurality of processing chambers. The plurality of processing chambers includes a first precursor reaction chamber that exposes the surface of the web substrate to a desired partial pressure of first precursor gas, thereby forming a first layer on the surface of the web substrate. A purging chamber purges the surface of the web substrate with a purge gas. A vacuum chamber removes gas from the surface of the substrate. A second precursor reaction chamber exposes the surface of the web substrate to a desired partial pressure of the second precursor gas, thereby forming a second layer on the surface of the web substrate.
