Patent ID: 8653657

Claim:
A semiconductor chip to be bonded to a bonding object in a state of opposing a surface of the semiconductor chip to the bonding object, comprising: a first functional bump projected from the surface with a first projection amount, the first functional bump for establishing an electrical connection to electrically connect the semiconductor chip with the bonding object; a first connection confirmation bump projected from the surface with a second projection amount smaller than the first projection amount, the first connection confirmation bump used for confirming a state of the electrical connection established by the first functional bump; a semiconductor substrate; a surface protective film covering a surface of the semiconductor substrate; and an electrode pad interposed between the semiconductor substrate and the surface protective film and arranged to face a pad opening formed in the surface protective film, wherein the first functional bump is provided on the electrode pad so that the first projection amount projects from the surface protective film through the pad opening, and the first connection confirmation bump heaps up on a heap position which is closer to the semiconductor substrate than a position of the electrode pad, and the second projection amount projects from the surface protective film through a through-hole penetrating the surface protective film, and the bonding object includes a second functional bump projected from a surface of the bonding object with a third projection amount, the second functional bump for establishing an electrical connection to electrically connect the bonding object with the semiconductor chip, and a second connection confirmation bump projected from the surface of the bonding object with a fourth projection amount smaller than the third projection amount, the second connection confirmation bump used for confirming a state of the electrical connection established by the second functional bump.
