Assignee: TOKYO ELECTRON LIMITED
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 1:
2. The measurement method according to claim 1, further comprising:
e) obtaining intensity of the signal of the resonance frequency of at least one sensor device of the plurality of sensor devices installed in the jig using the third measurement data calculated in c),
f) obtaining intensity of noise using the first measurement data acquired in a),
g) calculating a signal-to-noise (S/N) ratio that is a ratio of the intensity of the signal obtained in e) to the intensity of noise obtained in f);
h) determining whether the S/N ratio is greater than a predetermined threshold; and
i) estimating a temperature based on the signal of the resonance frequency of the at least one sensor device, in response to the S/N ratio being greater than the predetermined threshold.
