Abstract
A feed system and related process are configured to continuously feed measured doses of source material to a vapor deposition apparatus wherein the source material is sublimated and deposited as a thin film on a substrate. The system includes a bulk material hopper, and an upper dose cup disposed to receive source material from the hopper. A lower dose cup is disposed in a vacuum lock chamber to receive a measured dose of source material from the upper dose cup. A transfer mechanism is disposed below the vacuum lock chamber to receive the measured dose of source material from the lower dose cup and to transfer the source material to a downstream deposition head while isolating the deposition conditions and sublimated source material within the deposition head.
