  • Patent number: 11742657
    Abstract: An electrostatic discharge (ESD) protection circuit includes a first transistor, a second transistor, a capacitor, a voltage dividing circuit, and a first diode. The first transistor is coupled between a first power rail and a second power rail. The second transistor is coupled between the first power rail and the second power rail. A bulk of the second transistor is coupled to a control terminal of the first transistor. The capacitor is coupled between the first power rail and a control terminal of the second transistor. The voltage dividing circuit is coupled between the control terminal of the second transistor and the second power rail, and has a divided voltage output terminal coupled to the bulk of the second transistor. The first diode is coupled between the divided voltage output terminal and the second power rail.

  • Publication number: 20230260934
    Abstract: Disclosed are a plasma damage protection device and a plasma damage protection method. The plasma damage protection device is disposed in an integrated circuit. The plasma damage protection device includes a switch component and a transmission structure. The switch component is coupled between a reference power rail and a pad. The switch component is turned on or cut off according to a charge on the pad. The pad is coupled to a protected component. The transmission structure is configured to transmit the charge on the pad to a control end of the switch component during a back-end-of-line process. The switch component is turned on according to the charge on the pad during the back-end-of-line process.

  • Publication number: 20230142717
    Abstract: An electrostatic discharge protection circuit, including a discharge switch, a first transistor, an inverter, and a feedback circuit, is provided. The discharge switch is coupled between a first power rail and a second power rail, and may be turned on or cut off according to a control voltage. The first transistor has a first end coupled to the first power rail. A control end of the first transistor receives the control voltage. The inverter is coupled between a second end of the first transistor and a control end of the discharge switch. The feedback circuit is coupled between an output end and an input end of the inverter and is configured to determine whether to provide a turn-on path between the input end of the inverter and the second power rail according to the control voltage.
