Semiconductor device having bonding pads and probe pads
An external connection wire is externally connected and is bonded to a portion of a predetermined exposed region of a bonding pad, which is exposed through a bonding pad opening of a passivation film. The bonding pad opening of the passivation film has a polygonal shape that has a plurality of corners, and each of the plurality of corners has an obtuse angle or is chamfered. A probe pad is electrically connected to the bonding pad through a conductive line covered with the passivation film. The passivation film is also located on the probe pad and further includes a probe pad opening, through which a predetermined exposed region of the probe pad is exposed. The probe pad opening has a polygonal shape that has a plurality of corners, and each of the plurality of corners has an obtuse angle or is chamfered.
