    Abstract: A semiconductor processing system includes a chamber arrangement, an exhaust arrangement connected to the chamber arrangement, an accretion sensor supported within the exhaust arrangement, and a processor. The processor is disposed in communication with the accretion sensor and is responsive to instructions recorded on a non-transitory machine-readable medium to receive an accretion signal from the accretion sensor, the accretion signal indicative of an accretion amount disposed within the exhaust arrangement, receive a predetermined accretion amount value, and compare the accretion amount to the predetermined accretion amount value. The instructions further cause the processor to execute an accretion countermeasure when the received accretion amount is greater than the predetermined accretion amount value. Methods of controlling accretion within exhaust arrangements for semiconductor processing systems and foreline assemblies for semiconductor processing systems are also described.
