In the present invention, discrete decoupling capacitors are mounted on the surface of an IC chip. Since a discrete capacitor can provide the capacitance of the magnitude μF, the attached capacitors can serve as the local power reservoir to decouple the external power ground noise caused by wirebonds, packages, and other system components.

An integrated circuit module has a common function known good integrated circuit die with selectable functions. The selectable functions arc selected during packaging of the known good integrated circuit die. The known good integrated circuit die is mounted to a second level substrate. The second level substrate has wiring connections to the input/output pads of the known good integrated circuit die that select desired input functions and output functions. Further, the wiring connections on the second level substrate provide signal paths to transfer signals to the desired input function and signals from the desired output function, and signals to and from the common functions. Also, the wiring connections form connections between the input/output pads and external circuitry. To select the desired input functions and the desired output functions, appropriate logic states are applied to input/output pads connected to a function selector to configure a functional operation of the integrated circuit module. The second level module substrate has connector pins to provide physical and electrical connections between the external circuitry and the wiring connections on the second level substrate.

A barrier layer is deposited over a layer of passivation including in an opening to a contact pad created in the layer of passivation. A column of three layers of metal is formed overlying the barrier layer and aligned with the contact pad and having a diameter that is about equal to the surface of the contact pad. The three metal layers of the column comprise, in succession when proceeding from the layer that is in contact with the barrier layer, a layer of pillar metal, a layer of under bump metal and a layer of solder metal. The layer of pillar metal is reduced in diameter, the barrier layer is selectively removed from the surface of the layer of passivation after which reflowing of the solder metal completes the solder bump of the invention.
