TSMC has obtained patents for power supply devices, semiconductor process systems, and power management methods, enabling the power supply device to enter emergency backup mode

On April 1, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Taiwan Integrated Circuit Manufacturing Co., Ltd. had obtained a patent entitled "Power Supply Device, Semiconductor Process System and Power Management Method", with the authorization announcement number of CN112751406B, and the application date of October 2019.

The patent abstract shows that a power supply device is provided, including a power supply unit, a power sensor, and a control unit. The power unit includes a first power supply and a second power supply in parallel configuration, which respectively provide the first output power and the second output power to the semiconductor process equipment. The power sensor senses whether the output parameters of the first output power supply and the second output power supply are less than the preset value. When one of the output parameters of the first output power supply and the second output power supply is less than the preset value, the power supply device enters an emergency backup mode. The control unit enables the other of the first power supply and the second power supply to provide a backup power supply to the semiconductor process equipment. The output parameter of the backup power supply is greater than that of the first output power supply and the second output power supply.
