Chamber matching by equipment constant updates

A system, comprising memory and a processing device coupled to the memory, wherein the processing device is to:

• receive data indicative of performance of a plurality of process chambers;
• provide the data indicative of performance of a plurality of process chambers to a model;
• receive as output from the model a first recommended equipment constant update associated with a first process chamber of the plurality of process chambers and a second recommended equipment constant update associated with a second process chamber of the plurality of process chambers;
• and
• update a first equipment constant of the first process chamber and a second equipment constant of the second process chamber in view of the first recommended equipment constant update and the second recommended equipment constant update.

A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• receiving, by a processing device, data indicative of performance of a plurality of process chambers;
• providing the data indicative of performance of a plurality of process chambers to a model;
• receiving as output from the model a first recommended equipment constant update associated with a first process chamber of the plurality of process chambers and a second recommended equipment constant update associated with a second process chamber of the plurality of process chambers;
• and
• updating a first equipment constant of the first process chamber and a second equipment constant of the second process chamber in view of the first recommended equipment constant update and the second recommended equipment constant update.
