摘要:
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.

Thin films are produced by a method wherein a material is heated in a furnace placed inside a vacuum system. An inert gas is flown over/through the heated material. The vapors of the material are entrained in the carrier gas which is then directed onto a substrate heated to a temperature below that of the furnace temperature and placed in close proximity to the exit of the furnace.

A new, large-area, thin-film, flexible photovoltaic structure is disclosed, as well as a general fabrication procedure, including a preferably roll-to-roll-type, process-chamber-segregated, “continuous-motion”, method for producing such a structure. A special multi-material vapor-deposition environment is disclosed to implement an important co-evaporation, layer-deposition procedure performed in and as part of the fabrication procedure. A structural system adapted to create a vapor environment generally like that just referred to is disclosed, as is an organization of method steps involved in the generation of such a vapor environment. Also, a unique, vapor-creating, materials-distributing system, which includes specially designed heated crucibles with carefully arranged, spatially distributed, localized and generally point-like, heated-nozzle sources of different metallic vapors, and a special multi-fingered, comb-like, vapor-delivering manifold structure is shown.

A thermal evaporation source includes: a crucible configured to contain a volume of evaporant and a vapor space above the evaporant; a manifold body having within it a hollow expansion chamber that is flowably connected to the vapor space via one or more restriction orifices; one or more effusion nozzles flowably connected to the expansion chamber and exiting an outer surface of the thermal evaporation source, the nozzle(s) oriented to direct an evaporant vapor flow out of the source vertically downward, in one or more horizontal directions, or in one or more directions intermediate between horizontal and vertically downward; and a heater capable of heating some or all of the thermal evaporation source to a temperature sufficient to produce the one or more evaporant vapor flows when a vacuum is applied to the thermal evaporation source.
