Abstract:
A semiconductor integrated circuit device having a multichip structure, comprising:first and second semiconductor chips, each comprising: a test pad to be touched with a probe during inspection; an external connection pad connected to the test pad by way of a conductor; first and second voltage application pads; a first mount-assist pad connected to the first voltage application pad and provided near the external connection pad; a second mount-assist pad connected to the second voltage application pad and provided near the external connection pad; a first protection diode having one end connected to the first voltage application pad and having another end connected to the test pad; and a second protection diode having one end connected to the second voltage application pad and having another end connected to the test pad; and a bump applied, with the first and second semiconductor chips placed so as to face each other, between the first and second semiconductor chips so as to bridge the external connection pads and the mount-assist pads of both of the first and second semiconductor chips so that the external connection pads and the mount-assist pads are short-circuited together and the first and second chips are bonded firmly together.
