Integrated circuit device

An integrated circuit device, comprising:

• a substrate, wherein a first circuit, a second circuit, at least one interconnect line and an electrostatic discharge protection circuit are embedded in the substrate;
• a first internal bonding pad, disposed on a surface of the substrate and exposed outside of the substrate, and the first internal bonding pad being electrically connected to the first circuit;
• a second internal bonding pad, disposed on the surface of the substrate and exposed outside of the substrate, and the second internal bonding pad being electrically connected to the second circuit;
• an external bonding pad, disposed on the surface of the substrate and exposed outside of the substrate;
• and
• a bonding wire, wherein the first internal bonding pad is electrically connected to the second internal bonding pad via the bonding wire, the first internal bonding pad is electrically connected to the electrostatic discharge protection circuit via the interconnect line, the electrostatic discharge protection circuit is electrically connected to the external bonding pad, and the external bonding pad is used for electrically connecting to an external package lead.
