Abstract
Continuous vapor deposition apparatus for coating objects with a coating material, e.g., parylene, are disclosed. The apparatus comprise an entrance chamber for loading the objects, a process chamber for coating the objects, and an exit chamber for removing the objects. Coating material is introduced into the process chamber under vacuum conditions in a vaporized state. The pressure in the process chamber can be controlled by modulating the rate of introduction of the coating material with a modulating valve in response to the pressure in the process chamber. A process for continuously coating objects by vapor deposition under vacuum conditions, suitable for use in the apparatus, is also disclosed.
