Patent ID: 10818526

Abstract:
The present invention relates to an apparatus of controlling a temperature of a wafer cleaning equipment capable of quickly and accurately determining a detection abnormality of a temperature sensor located inside a cleaning tank, and a method of controlling a temperature using the same.The apparatus of controlling a temperature of a wafer cleaning equipment and the method of controlling a temperature using the same according to the present invention may determine an abnormal operation of a first temperature sensor installed at an inner side of an inner tank by comparing a measurement value of the first temperature sensor installed at the inner side of the inner tank and a measurement value of a second temperature sensor installed at a transfer robot configured to transfer wafers to the inner side of the inner tank.Meanwhile, a method of controlling a temperature of a wafer cleaning equipment according to the present invention may determine an abnormal operation of temperature sensors by comparing measurement values of the temperature sensors installed at an inner side of each of inner tanks in a state of supplying deionized water of a set temperature to each of the inner tanks after discharging a cleaning solution accommodated in each of the inner tanks of a plurality of cleaning tanks.
