Patent ID: 8212366

Claim:
A semiconductor device formed by flip-chip bonding a semiconductor chip to a carrier used for external connection with the semiconductor chip, the semiconductor chip comprising: a plurality of input/output (I/O) cells each including a circuit element and an electrode pad formed on the circuit element so that at least a portion of the electrode pad overlaps the circuit element in plan view, the plurality of I/O cells including a first I/O group which is disposed adjacent a corner cell, wherein the first I/O group includes at least two first I/O cells each having an inner electrode pad as the electrode pad and at least two second I/O cells each having an outer electrode pad as the electrode pad, and a plurality of electrode pads of the at least two first and second I/O cells included in the first I/O group are configured in a zigzag pad arrangement so as to form inner and outer pad arrays, and wherein one of the inner electrode pads of the at least two first I/O cells is bump-bonded to an interconnect pattern formed on a surface of the carrier, and the other of the inner electrode pads of the at least two first I/O cells is not connected to an interconnect pattern formed on a surface of the carrier.
