Patent ID: 8604627

Claim:
A semiconductor device, sealed with resin, in which a semiconductor chip is die-bonded to a surface of an island, a first end of a first wire is wire-bonded to an electrode formed on a surface of the semiconductor chip to form a first bonding section, and a second end of the first wire is wire-bonded directly to the island to form a second bonding section, wherein the island is made of an electrical conductor, the semiconductor chip and the island are sealed with the resin, a double bonding section formed by wire-bonding a second wire is provided on the second bonding section of the first wire wire-bonded onto the island, the second bonding section having an extended portion formed by the second end of the first wire pressed directly on the island, a first end of the second wire being connected onto the second bonding section, a second end of the second wire being connected to the surface of the island, the first end of the second wire being in direct contact with the first wire on the extended portion to form the double bonding section, further comprising a lead terminal electrically connected with the semiconductor chip, wherein the second end of the first wire and the second end of the second wire are directly attached to the island, the first end of the first wire and the first end of the second wire are indirectly attached to the island, and a difference in height between the first end of the first wire and the first end of the second wire is the same as a thickness of the semiconductor chip, wherein the lead terminal and the semiconductor chip are connected by a third wire, the lead terminal is provided separately from the island and the third wire is provided separately from the first wire.
