Abstract
A method of sequential deposition of source materials onto a web substrate. A substrate transfer mechanism imparts continuous movement of a substrate past a plurality of deposition sources during vapor deposition of deposition source materials. Every portion of the substrate is exposed to deposition fluxes from the deposition sources in an alternating periodic manner. The number of source exposures is greater than the number of sources.
