Abstract
The present disclosure discloses an apparatus for protection against electrostatic discharge and a method of manufacturing the same. The apparatus comprises: a first input/output pad electrically connected to an input/output pin and comprising an input/output protection circuit provided between a power source line and a ground line, wherein the input/output protection circuit is configured to release an electrostatic discharge current generated at the input/output pin; and a second input/output pad which is an empty pad electrically connected to the input/output pin and an RF input/output terminal of an internal RF circuit and is configured to receive a signal from the input/output pin and transmit the signal to the internal RF circuit. With the above apparatus, parasitic capacitive load can be minimized while electrostatic protection is performed on the RF circuit.
