  • Patent number: 11874609
    Abstract: A temperature control device and a temperature control method are provided. The temperature control device is located at an interface between a photoresist coating and developing machine and a lithography machine and includes: a temperature detection device, a gas flow generator and a controller. The temperature detection device and the gas flow generator are respectively connected to the controller. The temperature detection device is configured to detect an actual temperature at the interface in real time. The gas flow generator is at least configured to generate a gas flow sealing knife around the interface. The controller is configured to control the gas flow generator to generate the gas flow sealing knife responsive to that the actual temperature detected by the temperature detection device is not equal to the target temperature, to control the actual temperature at the interface to reach the target temperature through the gas flow sealing knife.
