Claim Text:
1. A semiconductor processing system comprising: a plurality of sensors that measure physical conditions of the semiconductor processing system; a buffer electrically coupled with at least a subset of the plurality of sensors to store sensor data at a first sampling rate; a long term storage device electrically coupled with the buffer to store data stored at the buffer and wherein the long term storage device has a second sampling rate that is less than the first sampling rate of the buffer; and a controller electrically coupled to the buffer and the long term storage device, wherein the controller is configured to cause the sensor data stored at the buffer to be stored into the long term storage device at or below the second sampling rate that is less than the first sampling rate, and the controller is configured to, in response to a fault event, automatically output data stored in the long term storage device to a user.
