1. A method of producing a semiconductor device including a semiconductor element and a conductive member to which the semiconductor element is bonded,wherein the conductive member is plated with a metal layer on the surface thereof, an interior portion of the conductive member has a lower electrical resistivity than the metal layer,the method comprising the steps of:

  • setting a Sn-(3-7)Cu solder having a Cu6Sn5 content between the semiconductor element and the metal layer plated conductive member; and

    depositing the Cu6SN5 grains on the metal layer plated conductive member by heating the Sn-(3-7)Cu solder, the Cu6SN5 grains being layered on the plated metal layer.
