Claims6
A vapor deposition system comprising:
- a vaporizer;
- a reaction chamber downstream from the vaporizer in the vapor deposition system;
- a first gas feed line connecting the vaporizer to the reaction chamber;
- a gas feed valve in-line with the first gas feed line between the reaction chamber and the vaporizer;
- and
- a second gas feed line connected to the first gas feed line between the gas feed valve and the reaction chamber, the second gas feed line being connected to a carrier gas source upstream from the reaction chamber;
- wherein the gas feed line further comprises a 4-way gas feed valve in-line with the first gas feed line between the reaction chamber and the vaporizer and in-line with the carrier gas source and an exhaust line connected to an exhaust pump.
