Abstract:
1. An apparatus for vapor deposition of a sublimated source material as a thin film on a substrate, said apparatus comprising: a receptacle configured to hold a source material; a distribution plate positioned above the receptacle, wherein the distribution plate defines a pattern of passages therethrough; a conveyor defining a pair of raised edges and a transfer surface such that the raised edges are raised with respect to the transfer surface, wherein the conveyor is configured to travel in a continuous loop such that the transfer surface passes above the distribution plate in a first direction to receive thereon sublimated source material passing through the passages of the distribution plate, and wherein the conveyor is configured to travel in a second direction while carrying a substrate on the raised edges; a heating system configured to heat the conveyor while it travels in the second direction; and a cooling system configured to cool the conveyor while it travels in the first direction, wherein the heating system and the cooling system are positioned within the continuous loop defined by the conveyor.
