Abstract: In accordance with an embodiment of the present invention, a method of forming a semiconductor device includes forming a contact layer over a first major surface of a substrate. The substrate includes device regions separated by kerf regions. The contact layer is disposed in the kerf region and the device regions. A structured solder layer is formed over the device regions. The contact layer is exposed at the kerf region after forming the structured solder layer. The contact layer and the substrate in the kerf regions are diced.
