Nozzle-Based, Vapor-Phase, Plume Delivery Structure for Use in Production of Thin-Film Deposition Layer

A physical vapor deposition effusion method comprising translating a strip material through a physical vapor deposition zone in a deposition chamber and providing first and second substantially closed vessels located serially along the processing path in the same deposition chamber, each vessel emitting different source materials to produce overlapping plumes and having an array of vapor delivery nozzles distributed uniformly across the vessel along the width of the zone, and configured to expel overlapping plumes to create a fog having a substantially uniform composition across the width and a varying composition across the length of the zone. Also, an elongate vapor deposition effusion vessel having an elongate lid including plural nozzles spaced from each other along its elongate axis, and a continuous heating element in the lid encircling the plural nozzles, the heating element having electrical contacts connected to an electrical source on the same side of the vessel.
