ABSTRACT:
In a power supply disconnection cell, a power supply connection switch is added in parallel to a protection transistor having a fixed gate. The power supply connection switch electrically connects or disconnects a plurality of power supplies according to a control signal externally input through an external control terminal. In a WLBI process, a plurality of power supplies are connected by the power supply connection switch, and therefore, a voltage is applied to other power supply pads by voltage application to a specific input terminal. After the WLBI process, the power supplies are disconnected, and electric charges produced by an abnormal voltage, such as a surge, or the like, are released by the protection transistor provided between the power supplies, whereby breakdown of a semiconductor device is prevented.
