Abstract
A method includes determining, based on sensor data, that one or more components of substrate processing equipment are within a pre-failure window that is after a normal operation window. Corresponding data points in the normal operation window are substantially stable along a first health index value. The corresponding data points in the pre-failure window increase from the first health index value to a peak at a second health index value. Responsive to the determining that the one or more components are within the pre-failure window, the method further includes causing performance of a corrective action associated with the one or more components of the substrate processing equipment.
Claims20
A method comprising:
- determining, based on sensor data, that one or more components of wafer or display manufacturing equipment are within a pre-failure window that is after a normal operation window, wherein corresponding data points in the normal operation window are substantially stable along a first health index value, wherein the corresponding data points in the pre-failure window increase from the first health index value to a peak at a second health index value;
- and
- responsive to the determining that the one or more components are within the pre-failure window, causing performance of a corrective action associated with the one or more components of the wafer or display manufacturing equipment.
A method comprising:
- identifying historical sensor data associated with wafer or display manufacturing equipment;
- and
- identifying historical windows associated with the historical sensor data, wherein:
- corresponding data points of the historical sensor data in a normal operation window of the historical windows are substantially stable along a first health index value;
- the corresponding data points of the historical sensor data in a pre-failure window of the historical windows increase from the first health index value to a peak at a second health index value;
- and
- the historical sensor data and the historical windows are to be used to determine, based on current sensor data, whether one or more components are within the pre-failure window to cause performance of a corrective action associated with the one or more components.
A system comprising:
- a memory;
- and
- a processing device coupled to the memory, the processing device to:
- determine, based on sensor data, that one or more components of wafer or display manufacturing equipment are within a pre-failure window that is after a normal operation window, wherein corresponding data points in the normal operation window are substantially stable along a first health index value, wherein the corresponding data points in the pre-failure window increase from the first health index value to a peak at a second health index value;
- and
- responsive to determining that the one or more components are within the pre-failure window, cause performance of a corrective action associated with the one or more components of the wafer or display manufacturing equipment.
