  • Publication number: 20170011974
    Abstract: A substrate processing apparatus includes a substrate heating part, a power supply part and a control device. The control device measures a temperature of the substrate while controlling the substrate heating part such that the temperature of the substrate reaches a first control temperature higher than the target temperature using power supplied by the power supply part. The device measures the temperature of the substrate for a second control temperature lower than the target temperature, and selects the power ratio value providing the best temperature uniformity in the plane of the substrate and a temperature average value for the selected power ratio value from a result of the measurement. The device calculates a control temperature and the power ratio value for the target temperature based on the selected temperature average value and the power ratio value for each of the first and second control temperature.

  • Patent number: 9244447
    Abstract: To provide a substrate processing apparatus, including a control unit that performs control to transfer a prescribed substrate into each chamber, wherein when error is detected during transfer of the substrate, the control unit performs control to: specify a place where the error is generated; select a fallback operation table according to a processing status of the substrate, which is the table defining a processing content for each part of the substrate processing apparatus including the place where the error is generated; and transfer the substrate based on the selected fallback operation table.

  • Publication number: 20130253689
    Abstract: Provided is a substrate processing apparatus which may update an accumulated film thickness of each dummy substrate when a dummy substrate carrier is reloaded. The substrate processing apparatus includes: a process chamber where a plurality of substrates including a dummy substrate are processed; a substrate receiving unit whereon a dummy substrate carrier accommodating at least the dummy substrate is placed; a memory unit configured to store a film thickness of the dummy substrate in the dummy substrate carrier when the dummy substrate carrier is unloaded from the substrate receiving unit; and a management unit configured to update the film thickness of the dummy substrate in the dummy substrate carrier based on the film thickness stored in the memory unit when the dummy substrate carrier is reloaded onto the substrate receiving unit.
