Patent number: 11569104Abstract: 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.Type: GrantFiled: December 28, 2018Date of Patent: January 31, 2023Inventors: Takashi Ota, Masayuki Hayashi, Jiro Okuda, Akihiro Nakashima
