  • Patent number: 11569104
    Abstract: A substrate processing apparatus includes a temperature detector and a controller. The temperature detector detects a temperature of processing liquid before the temperature of the processing liquid in pre-dispensing in progress reaches a target temperature. The controller sets discharge stop duration of the processing liquid in the pre-dispensing based on target temperature prediction duration. The target temperature prediction duration is prediction duration until the temperature of the processing liquid reaches the target temperature from a detection temperature. The detection temperature is the temperature of the processing liquid detected by the temperature detector before the temperature of the processing liquid reaches the target temperature. The target temperature prediction duration is determined based on a temperature profile.

  • Publication number: 20220367218
    Abstract: The substrate has a plurality of chip regions each being provided with a structure to be a power device, and is provided with a to-be-processed film. The thickness profile of the to-be-processed film in the radial direction is measured by scanning with the sensor in the radial direction while the substrate is rotated. The average thickness of the thickness profile is calculated. At least one radial position where the thickness profile has an average thickness is extracted as at least one candidate position. At least one of the at least one candidate position is determined to be at least one measurement position. Processing liquid is supplied from a nozzle onto the to-be-processed film of the substrate while the substrate is rotated. The sensor monitors the time-dependent change in the thickness of the to-be-processed film in at least one measurement position while the substrate is rotated.

  • Publication number: 20220063677
    Abstract: A travel controller performs driving control of a vehicle at an autonomous driving level that is a first autonomous driving level in which a driver of the vehicle is not obligated to watch or a second autonomous driving level in which the driver is obligated to watch; notifies, for a predetermined period, the driver of a request for driving the vehicle or taking a driving posture allowing for the driving, when the autonomous driving level of the driving control changes from the first autonomous driving level to the second autonomous driving level; and determines an attention level of the driver, based on an output of a sensor provided for the vehicle. The attention level is a level of attention to driving. The travel controller further modifies the predetermined period so as to be shorter when the determined attention level is high than when the attention level is low.
