Patent ID: 8349084

Claim:
A vapor deposition apparatus, said apparatus comprising: a deposition head; a receptacle disposed in said deposition head, said receptacle configured for receipt of a granular source material; a distribution plate disposed between a supply of source vapor and a substrate conveyed through the apparatus, said distribution plate comprising a plurality of passages therethrough; a conveyor disposed below said deposition plate such that the substrates are supported below said distribution plate, wherein said conveyor is configured to convey the substrates at a constant linear speed through said apparatus between an entry slot and an exit slot such that leading and trailing sections of the substrates are exposed to generally the same vapor deposition conditions within said deposition head in a direction of conveyance of the substrates through said apparatus; and, a gas tank connected to an exit port via a gas source line, wherein the exit port is positioned to supply a gas through the distribution plate to a deposition surface of the substrate conveyed through said apparatus on said conveyor, wherein upon heating the granular source material, source material vapors are created to pass through the distribution plate to the substrate.
