Method and apparatus for measuring substrate temperatures

A method of correcting a temperature probe reading in a thermal processing chamber for heating a substrate, including the steps of heating the substrate to a process temperature and using a first, a second and a third probe to measure the temperature of the substrate.

The feed injector (2) includes a feed injector tip (6) having an opening, the feed injector tip being in fluid communication with a feed inlet (8) and a flange connector (4), the flange connector being in optical alignment with the opening of the feed injector tip. A blind flange (10) should be sized to fit on the flange connector of the feed injector and thereby form a gas pressure resistant seal. A pressure sealing gland (12) is fitted in the blind flange such that a light conduit (22a or 22b) can pass through the blind flange and that the receiving end of the light conduit extends into the feed injector such that the light receiving end of the light conduit is in optical alignment with the opening of the feed injector tip. An optical coupler (26a or 26b) functions as an optical connection between the light transmitting end of the light conduit to a fiber optic cable (28a or 28b) and thus to an optical pyrometer.

The controller checks whether temperature difference exceeds a temperature ceiling range which is fixed or not and generates an emergency signal or a shut-off signal according to a checked result. A touch screen(130) indicates the temperature of the connection unit and the ambient temperature and outputs an alerting message. A robustness assessment unit(140) collects temperature data and analyzes data about the temperature of the connection unit and a deterioration progress. The robustness assessment unit utilizes an analyzed result and calculates a robustness assessment index.
