    • PURPOSE: A semiconductor device and a manufacturing method thereof are provided to minimize stress applied to a bonding pad by forming a copper filler at a position except the bonding pad of the semiconductor chip. CONSTITUTION: A semiconductor chip of a wafer state is provided. A seed metal layer(24) is extended from the bonding pad of the semiconductor chip. A copper filler is plated on the end of the seed metal layer. A rewiring plating line(38) is formed when the copper filler is plated. The rewiring conductive line is plated between the start part of the seed metal layer connected to the bonding pad and the copper filler. A buffer member(36) is attached to the surface of the seed metal layer and is inputted to the rewiring plating line and the copper filler.
