Abstract: An electronic system includes a memory and a processor. The memory stores first setting data of a manufacturing process condition of semiconductor manufacturing equipment. The processor judges whether a change has occurred in the semiconductor manufacturing equipment based on first equipment data from the semiconductor manufacturing equipment and second equipment data stored in the memory before the first equipment data is received. The processor transmits second setting data to the semiconductor manufacturing equipment when the change has occurred in the semiconductor manufacturing equipment and stores the first equipment data in the memory when no change has occurred in the semiconductor manufacturing equipment. The second setting data corresponds to updated first setting data.
