Abstract
A source vessel for use in a semiconductor processing system to supply precursor materials by providing enhanced control over vapor pressures. The source vessel includes a housing or vessel defining a chamber for holding a volume of precursor in a liquid state. The source vessel further includes a temperature sensor configured to detect a temperature of a surface of the liquid-state precursor that is presently contained within the chamber of the housing. The temperature sensor may take the form of a temperature measurement device such as a thermocouple on a float or a non-contact temperature measurement device such as an infrared (IR) temperature sensor with a line-of-sight to the liquid's surface.
