US Patent 7538414 Semiconductor integrated circuit device

Disclosed is a semiconductor IC device capable of suppressing the interference of noise generated in one functional block with other functional blocks therein while protecting against electrostatic breakdown. A plurality of isolated pads are connected to a first terminal through respective wires, and further connected to a plurality of isolated pads each connected to a second terminal having the same function as that of the first terminal, so as to reduce noise interference based on the pad isolation and protect against electrostatic breakdown based on the inter-pad connection.
