Patent ID: 6897669

Claim:
A semiconductor device comprising: a substrate; a bonding pad that is located on one side of the substrate; a passivation film that is provided on the bonding pad and that has a bonding pad opening through which a predetermined exposed region of the bonding pad is exposed; an external connection wire that is externally connected and that is bonded to a portion of the predetermined exposed region of the bonding pad, which is exposed through the bonding pad opening of the passivation film, wherein the bonding pad opening of the passivation film has one of: a polygonal shape that has a plurality of corners, wherein each of the plurality of corners has an obtuse angle or is chamfered; a generally circular shape; a generally ellipsoidal shape; and a probe pad that is located on the one side of the substrate and is electrically connected to the bonding pad through a conductive line covered with the passivation film, wherein: the probe pad is provided to be engaged with an inspection probe at time of testing the semiconductor device; 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; and the probe pad opening of the passivation film has one of: a polygonal shape that has a plurality of corners, wherein each of the plurality of corners has an obtuse angle or is chamfered; a generally circular shape; and a generally ellipsoidal shape.
