US Patent 11286562 Gas-phase chemical reactor and method of using same

A gas-phase chemical reactor, a system including the reactor, and methods of using the reactor and system are disclosed. An exemplary reactor includes a reaction chamber and is configured to provide a precursor within the reaction chamber for a soak period—e.g., a period wherein a supply of the precursor to the reaction chamber is ceased and before purging of the reaction chamber begins. This allows relatively high residence times, relatively high partial pressures of the precursor(s) and/or a relatively high absolute pressure to be obtained within the reaction chamber during substrate processing.
