A novel design and method of fabricating a semiconductor device. In a preferred embodiment, the present invention is a flip chip package including a BT substrate. On the side of the substrate facing the die, thin traces are formed of an enhanced conductive material. Conductive bumps such as eutectic solder balls are then mounted on the traces, and the die mounted to the bumps. The die then packaged and mounted to a printed circuit board using, for example, a ball grid array. |
