Abstract: An adapter for a deposition chamber includes an adapter body extending longitudinally about a central axis between an upper side and lower side opposite the upper side. The adapter body has a central opening about the central axis. The adapter body has a radially outer portion having a connection surface on the lower side and a radially inner portion having a coolant channel and a stepped surface on the lower side. At least a portion of the coolant channel is spaced radially inwardly from a radially inner end of the connection surface. At least the portion of the coolant channel is disposed longitudinally below the connection surface between the connection surface and the stepped surface.

Abstract: Aspects generally relate to methods, systems, and apparatus for conducting a calibration operation for a plurality of mass flow controllers (MFCs) of a substrate processing system. In one aspect, a corrected flow curve is created for a range of target flow rates across a plurality of setpoints. In one implementation, a method of conducting a calibration operation for a plurality of mass flow controllers (MFCs) of a substrate processing system includes prioritizing the plurality of MFCs for the calibration operation. The prioritizing includes determining an operation time for each MFC of the plurality of MFCs, and ranking the plurality of MFCs in a rank list according to the operation time for each MFC. The method includes conducting the calibration operation for the plurality of MFCs according to the rank list and during an idle time for the substrate processing system.

Abstract: Technologies directed to an eco-efficiency monitoring and exploration platform for semiconductor manufacturing. One method includes receiving, by a processing device, first data indicating an update to a substrate fabrication system having a first configuration of manufacturing equipment and operating to one or more process procedures. The method further includes determining, by the processing device, using the first data with a digital replica, environmental resource data. The digital replica includes a digital reproduction of the substrate fabrication system. The environmental resource usage data indicates an environment resource consumption that corresponds to performing the one or more process procedures by the substrate fabrication system incorporating the update. The method further includes providing, by the processing device, the environmental resource usage data for display on a graphical user interface (GUI).

Abstract: A method of analyzing completion of seasoning of semiconductor processing chambers may include training a model using seasoning cycle characteristics data obtained from existing semiconductor processing chambers. A supervised learning process may label the characteristics data based on expert determined identify seasoning completion and may optionally label the characteristics data based on chamber open event information or preventive maintenance information. The trained model may be used to characterize another chamber during seasoning to determine whether seasoning is completed and/or when or how long or how many seasoning cycles may be performed until seasoning is complete.
