Abstract:
An antenna effect discharge circuit is described for a device having patterned conductor layers, which may be exposed to charge inducing environments during a manufacturing process. The antenna effect discharge circuit has a terminal that is connected to a node on the device to be protected from charge accumulation and a gate, such as the gate of a field effect transistor in the circuit, and a terminal through which accumulated charge can be discharged to the substrate. A capacitor couples the gate in the antenna effect discharge circuit to the substrate. A voltage supply circuit is configured to provide voltage sufficient to bias the antenna effect discharge circuit in an off condition during operation of the device. A patterned conductor in the upper layer, and preferably the uppermost layer, of the device links the gate in the antenna effect discharge circuit to the voltage supply circuit.
