Patent ID: 8759987

Claim:
A semiconductor device comprising: a first wire having one end bonded to an electrode and another end bonded to a second bonding point at a portion other than the electrode; and a second wire having one end bonded on the first wire over the electrode and another end bonded to a third portion which is a portion different than the electrode, a bonding portion at the one end of the second wire covering at least a part of the upper surface and a part of a side surface of the first wire that extends from the second bonding point to the electrode, wherein a direction along which the second wire extends from the third portion to the bonding portion intersects a direction along which the first wire extends from the second bonding point to the electrode, wherein the first wire has a folded-back portion in which the first wire is extended from the end bonded to the electrode in a direction opposite to the second bonding point and then folded back toward the second bonding point, and wherein the one end of the second wire is bonded on the folded-back portion to cover at least a part of the side surface of the folded-back portion opposite from the third portion.
