Abstract
A semiconductor device includes a semiconductor chip having a terminal thereon, a lead frame for connection to an external device, a bonding wire connecting the terminal of the semiconductor chip and the lead frame. A mold resin layer encloses the semiconductor chip and the bonding wire, such that a portion of the lead frame extends out of the mold resin layer. A molecular bonding layer has a portion on a surface of the bonding wire and includes a first molecular portion covalently bonded to a material of the bonding wire and a material of the mold resin layer.
