  • Patent number: 7575370
    Abstract: The present invention provides precise temperature estimation in a heat treatment apparatus that estimates temperatures of process objects by using a thermal model and performs a heat treatment while performing a temperature control based on the estimated temperatures. The heat treatment apparatus (1) includes a processing vessel (11) accommodating plural wafers W, plural heaters (31 to 33) and plural temperature sensors (S1 to S5), and stores the thermal model. The heat treatment apparatus 1 estimates temperatures of the wafers W based on outputs of the temperature sensors (S1 to S5) by using the thermal model and controls the heaters (31 to 33) based on the estimated temperatures, applying a heat treatment to the wafers W. The thermal model for an individual apparatus is made by calibrating a standard thermal model designed for a standard apparatus.

  • Patent number: 6847015
    Abstract: Temperature control is made without the risk of contaminating object-to-be-processed and with high accuracy. Temperatures are metered out of contact with the objects-to-be-processed, and based on a metered result, estimated temperatures of the objects-to-be-processed are computed. Furthermore, estimation errors of the estimated temperatures are computed to correct the estimated temperatures. Based on a temperature recipe stating relationships between set temperatures and times and the corrected estimated temperatures, a heater is controlled.
