Abstract
A deposition apparatus includes a coating chamber and a coating zone within the coating chamber for coating work pieces. A heating source heats the coating zone, and a thermal hood within the coating chamber is located adjacent to the coating zone for controlling a temperature of the coating zone.
Claims16
A deposition apparatus comprising:
- a coating chamber;
- a coating zone configured to receive work pieces within the coating chamber for coating the work pieces;
- a heating source for heating the coating zone;
- and
- a thermal hood within the coating chamber adjacent to the coating zone for controlling a temperature of the coating zone, the thermal hood comprising a semi-cylindrical wall that wraps partially around the coating zone such that the coating zone is partially within the volume of the semi-cylindrical wall.
