An improved exhaust system for a gas-phase reactor and a reactor and system including the exhaust system are disclosed. The exhaust system includes a channel fluidly coupled to an exhaust plenum. The improved exhaust system allows operation of a gas-phase reactor with desired flow characteristics while taking up relatively little space within a reaction chamber.

Gas-phase reactor and system having exhaust plenum and components thereof

A system and method for providing intermediate reactive species to a reaction chamber are disclosed. The system includes an intermediate reactive species formation chamber fluidly coupled to the reaction chamber to provide intermediate reactive species to the reaction chamber. A pressure control device can be used to control an operating pressure of the intermediate reactive species formation chamber, and a heater can be used to heat the intermediate reactive species formation chamber to a desired temperature.
