    Abstract: A method capable of accurately measuring a physical quantity of a measurement object in a substrate processing apparatus. In a temperature measurement apparatus for implementing the method, two interference positions are measured at different timings when a reference mirror is caused to move in the direction away from a collimator fiber, and a difference between the two interference positions is calculated. When the reference mirror remote from the collimator fiber is caused to move toward the collimator fiber, two interference positions are measured at different timings, and a difference between the two interference positions is calculated. An average value of the interference position differences is calculated, an optical path length difference is determined from the average value, and a wafer temperature is calculated from the optical path length difference.

    Abstract: Remote sensing of the temperature of a greybody or blackbody radiator is effected by passing its radiation (24) through a modulated infrared filter spectrometer. The infrared filter comprises, in sequence, a band pass filter (20), a first polariser (21) which polarises the radiation, an electro-optical element (22) which splits the polarised radiation into two orthogonally polarised components, and a second polariser (23). A lens (28) images the radiation leaving the second polariser onto a detector (27). The electrical signal from the detector (27) is input to a numerical analyser. The electro-optical element (22), typically comprising a birefringent crystal assembly (25) and a birefringent trim plate (26), is configured so that the net optical delay of the orthogonally polarised components passed through it is such that the recombined components are at or near a peak or trough in their interferogram. A sinusoidally varying voltage is applied to the electro-optical element to modulate the net delay of the components passed through the electro-optical element. The numerical analyser is programmed to compute the harmonic amplitude ratio (the ratio of signal amplitudes at the fundamental and second harmonic of the frequency of the modulating voltage) of the signal that it receives from the detector (27). The harmonic amplitude ratio is a function of the temperature of the radiator, which can be estimated by reference to a calibration look-up table.

    Abstract: The present invention teaches a unique laser radiometer capable of accurately measuring the radiation temperature of a radiant surface and independently measuring the surface's emissivity. A narrow-band radiometer is combined with a laser reflectometer to measure concurrently radiance and emissivity of a remote, hot surface. Together, radiance and emissivity yield the true surface temperature of the remote target. A narrow receiver bandwidth is attained by one of two methods; (a) heterodyne detection or (b) optical filtering. A direct measurement of emissivity is used to adjust the value obtained for the thermal radiation signal to substantially enhance the accuracy of the temperature measurement for a given subject surface. The technique provides substantially high detection sensitivity over a very narrow spectral bandwidth.

    Abstract: A cavity thermal detector assembly (10) is presented that allows both tunable narrowband and broadband operation. This allows for high light efficiency, low thermal time constant, and flexibility in designing the optical path. The thermal detector/filter layers are part of the top mirror or mirrors (12) of a Gires-Tournois-type optical cavity and provide absorption and reflection that can be adjusted to the desired width and position of the detected band. Tuning, if desired, can be achieved by applying micromechanical methods. Broadband operation may be achieved by bringing the sensor close to the bottom mirror. In this mode, the sensor or its supports may or may not touch over a small area.
