Claim 9:
10. A device for forming a vaporized reactant, the device comprising:
a solid source vessel disposed in a first thermal zone at a first temperature;
a process control chamber downstream of and in fluid communication with the solid source vessel, the process control chamber disposed in a second thermal zone at a second temperature that is higher than the first temperature and configured to collect and transfer the vaporized reactant to a reactor downstream of the process control chamber;
a process control valve upstream of the process control chamber and disposed in the second thermal zone between the solid source vessel and the process control chamber; and
a control system configured to control operation of the process control valve based at least in part on feedback of measured pressure in the process control chamber.
