Assignee: HITACHI HIGH-TECH CORPORATION
Field: Control (Instruments)
Classification: CPC G  H | IPC G

Claim 1:
2. A diagnosis system that diagnoses a state of a device for measuring or inspecting a sample, the diagnosis system comprising:
a computer system configured to estimate a cause for an error occurring in the device,
wherein the computer system includes a learning device configured to learn, by machine learning, a correspondence between at least one of a recipe that defines an operation of the device, log data that describes the state of the device, or sample data that describes characteristics of the sample and a type of the error,
when the error occurs in the device after the learning device executes the machine learning, the computer system inputs at least one of the recipe used by the device when the error occurs, the log data when the error occurs, or the sample data when the error occurs to the learning device, so as to acquire an estimation result for at least one cause of the recipe, the state of the device, or the characteristics of the sample among the causes for the error as an output of the learning device and to output the estimation result,
wherein the learning device further learns a correspondence between at least one of an amount of variation in a recipe that defines an operation of the device, an amount of variation in log data that describes the state of the device, or an amount of variation in sample data that describes characteristics of the sample and an amount of variation in an inspection accuracy of the device, and
the computer system inputs at least one of a new recipe, new log data, or new sample data to the learning device, so as to acquire an estimation result for the amount of variation in the inspection accuracy of the device as an output of the learning device and to output the estimation result.
