Patent ID: 7030503

Claim:
A semiconductor device formed by flip-chip bonding a semiconductor chip to a carrier used for external connection with the semiconductor chip, wherein: the semiconductor chip includes: a plurality of input/output cells including circuit elements formed so as to be peripherally arranged on a surface of the semiconductor chip, and a plurality of electrode pads formed on associated ones of the input/output cells; the electrode pads are configured in a zigzag pad arrangement so as to form inner and outer pad arrays; and a predetermined area near a corner on the semiconductor chip surface is designated as a pad-disposition restriction area, within which disposing and usage of one or ones of the electrode pads that are bump-bonded to an interconnect pattern formed on a surface of the carrier are restricted, wherein in the pad-disposition restriction area, the inner pad array is individually bump-bonded to the interconnect pattern on the carrier surface, and at least two of the electrode pads are short-circuited to each other inside the carrier.
